Objective
Data regarding the diagnostic accuracy of Magnetic Resonance Imaging (MRI) are contradictory. The aim of this study was to find the accuracy of MRI knee against arthroscopy, in cases of meniscus and Anterior Cruciate Ligament (ACL) injuries. To the best of our knowledge, this is the largest Indian study comparing MRI knee with arthroscopy comprehensively.Subjects and methods
210 patients with knee injury who underwent both MRI knee and arthroscopy and either investigation showing ACL or meniscal tear were studied. MRI findings were correlated with arthroscopic findings, considering arthroscopy as the gold standard.Results
The sensitivity, specificity and accuracy of MRI in reference to arthroscopy for ACL tear was 97.46%, 90.38% and 95.71%, respectively; for Medial Meniscus (MM) tear was 95.69%, 94.87% and 95.23%, respectively; and for Lateral Meniscus (LM) tear was 86.04%, 97.01%, 88.09%, 96.42% and 94.76%, respectively. In ACL tear, mid substance tear was the most common site (66.03%) and discontinuity of ACL fibres was the most common pattern (42.8%). In meniscal tears, posterior horn was the most common site and vertical tears was the most common pattern.Conclusion
MRI is an excellent noninvasive imaging modality which can accurately detect and characterize various ligament tears of the knee joint. 相似文献3.

Purpose
To highlight the relationship between coraco-humeral distance and subscapularis tendon tear.Material and methods
Sixty-two shoulder MRI studies were examined. Twenty-two patients had partial or complete tear of subscapularis tendon and forty shoulder as a control group. Axial and oblique sagittal MR images were examined to measure the coraco-humeral distance followed by statistical analysis to correlate the distance with tendon tear.Results
A cut-off value of 8.25?mm for the coraco-humeral distance gave a sensitivity of 77.5% and specificity of 72.7% for subscapularis tendon tear.Conclusion
There is a well-known relationship between the coraco-humeral distance and the subscapularis tendon tear and its meticulous assessment in subjects with pain in the anterior shoulder region increases the diagnosis of subcoracoid impingement. 相似文献4.

Purpose
To assess the ability of MDCT to predict ligamentous and meniscal injuries in acute tibial plateau fractures compared to MR images.Patients and methods
Forty patients with acute tibial plateau fracture and 15 control subjects were subjected to MDCT and MR images. Lateral plateau depression (LPD) and lateral plateau widening (LPW) were measured in coronal MDCT images. Meniscal, cruciate, and collateral ligaments injuries were evaluated in MR images.Results
Soft tissue injuries incidence was not related to Schatzker type (P?>?0.05). LBD and LBW were different significantly between patients and control subjects ((P value?<?0.0011). LPD was correlated to meniscal, cruciate, and collateral ligaments injuries (P?<?0.05). LPW was correlated to cruciate and collateral ligaments tears (P?<?0.05) but not meniscal lesions (P?>?0.05). LPD?>?6?mm or LPW?>?7?mm increased possibility of Soft tissue injuries. Multiple soft tissue injuries were not related to Schatzker types (P?>?0.05). LPD and LPW were correlated with number of soft tissue injuries.Conclusion
MDCT measurements of LPD and LPW are correlated with incidence and number of ligamentous and meniscal injuries. MDCT can predict ligamentous and meniscal injuries without waiting for MRI in acute tibial plateau fractures. 相似文献5.

Background
Characterization of tendo-ligamentous pathologies of wrist remains problematic, despite advances in imaging. By using clinical history and imaging appearance, one can determine the diagnosis. USG is used as first imaging modality whereas MRI aids in making a specific diagnosis of few of the lesions.Aims
To investigate the etiological spectrum of tendo-ligamentous pathologies of wrist on USG & MRI with statistical correlation.Patients and methods
80 patients (male/female = 46/34) with complaint of swelling or pain in wrist were included and underwent USG and MRI of both the wrists.Results
The spectrum included ganglion cysts, vascular malformations, tenosynovitis, tendinopathy, ligament tears and fibrosis. The analysis was done using kappa coefficient and spearman's rho correlation coefficient. The strength of agreement between USG and MRI for the diagnosis of ganglion cysts, vascular malformations, tenosynovitis and tendinopathy was found to be very good.Conclusion
USG provides detailed depiction of superficial structures, is less expensive, and allows dynamic examinations of the wrist. It should be the first choice of investigation for majority of the cystic, tendinous, vascular, and fibrotic pathologies of the wrist. However, less promising results were observed for ligamentous pathologies on USG in our study. 相似文献7.

Introduction
Data assimilated for coronary arteries angiography by MDCT with retrospective (ECG) gating could be used for LV function without the need to repeat examination.Aim of the work
Is to study left ventricular segmental motility and global function using MDCT compared to MRI.Patients and methods
Fifty patients had cardiac MDCT and MRI studies within the same hour. LVEDV and LVESV volumes were measured. Consequently, the (EF) was calculated, for wall motion analysis, cine loops evaluated by two radiologists.Results
Excellent correlation between MDCT and MRI for the measurement of EDV (r2?=?0.962; p?<?0.001), and ESV (r2?=?0.988; p?<?0.001). Evaluation of EF revealed a good correlation between MDCT and MRI (r2?=?0.984; p?<?0.001) all by linear regression analysis. All the cardiac segments that shows dyskinesia or akinesia showed agreement between MDCT and MRI in cine images, the only disagreement in cases of mild hypokinesia detected only by MRI.Conclusions
High agreement between MDCT and MRI in the study of left ventricular segmental motility and global function. 相似文献8.

Aim
This study aimed to assess the role of multidetector computed tomography (MDCT) in detection and evaluation of severity of glenoid and humeral head bone loss in cases of recurrent anterior shoulder joint dislocation.Patients and methods
Twenty four patients were included in the study. MDCT with 3D VR examination was performed to both shoulders of all patients. The area of the missing glenoid was calculated as well as glenoid track and Hill-Sachs interval in cases of humeral head bone loss. The findings were compared with the intra operative arthroscopic results.Results
MDCT could detect minimal glenoid bone loss in 19 patients (79.2%), moderate glenoid bone loss in 4 patients (16.7%) and severe glenoid bone loss in 1 patient (4.2%), while arthroscope detected minimal loss in 16 patients (66.7%), moderate glenoid bone loss in 7 patients (29.2%) and significant glenoid bone loss in 1 patient (4.2%). Off-track Hill-Sachs lesions were detected by MDCT in 40% of patients and reduced to 35% of patients by arthroscopy.Conclusion
MDCT is an optimal imaging modality in preoperative evaluation of glenoid and humeral head bone loss. It is the most accurate radiologic method in evaluating the new concepts of on-track and off- track Hill-Sachs lesions. 相似文献9.

Back ground
In some patients suffering from chest pain, we must start by non-invasive coronary CT angiography (CCTA) to protect these patients from unnecessary invasive coronary catheter angiography (CCA).Objective
Value of CCTA as the first diagnostic imaging modality in patient suffering from chest pain.Patients and methods
A total number of 100 patients were included in this study with mean age of 53.51?±?11.6 years. Our patients were divided into two groups, group (A) included 60 patients underwent both CCTA and CCA and group (B) included 40 patients underwent CCTA only. Then Framingham Risk Score was applied for 68 cases (68%) after exclusion of cases with previous coronary artery intervention as CABG or stent (32 cases).Results
We were calculated a cutoff point of Framingham Risk Score at which p value <0.001, sensitivity 85.7%, specificity 51.5%, PPV 65.2%, NPV 77.3% and accuracy 69.1%, it was 7.5%. The diagnostic statistics of MDCT for CABG with sensitivity (100%) and specificity (100%).Conclusion
It is reasonable to start with CCTA in patients with Ferminghaim Risk Score less than 7.5%, filtering the patients to avoid unnecessary CCA. CCTA should be the first imaging modality in patients with CABG suffering from chest pain. 相似文献10.

Background
The ankle is frequently injured in trauma, overuse syndrome and inflammatory processes. Different imaging modalities assess the ankle, including plain radiography, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US).Purpose
Our objective is to assess the role of high resolution US as a valuable tool in the depiction of causes of ankle joint pain.Patients and methods
The study included 28 patients presented with ankle pain ranging in age from 17 to 60 years. They were examined by US and findings were correlated with MRI.Results
US was capable to detect various lesions (synovitis, arthritis, plantar fasciitis, tendon and ligamentous lesions). It had a sensitivity of 95.4%, a specificity of 83.3% and an overall accuracy of 92.8%. US had a limited value in detection of avascular necrosis (AVN), bone marrow oedema and fractures.Conclusion
US can be used as a first step diagnostic tool in cases of ankle pain. MRI should be spared to cases with negative or equivocal US findings. 相似文献11.

Purpose
To compare the role of ultrasonography and MRI in the diagnosis of synovitis involving wrist and hand joints in Rheumatoid arthritis patients.Materials and methods
Fifty patients with rheumatoid arthritis involving the wrist were subjected to hand and wrist ultrasonography Doppler and MRI and the results are compared and correlated during the period from December 2015 to January 2017.Results
Ultrasound detected synovial hypertrophy (pannus) in 42 wrist joints while MRI detected it in 46. Power Doppler detected increased vascularity within 30 wrist joints (60%), MRI detected synovial enhancement within 38 (76%). Power Doppler detected synovial activity (vascularity) in MCP joints of 13 patients and MRI detected synovial activity (enhancement) in MCP joints of 9 patients. Ultrasound detected erosions in 35 wrist and 27 MCP joints and MRI detected erosions in 37 wrist and 25 MCP joints. Ultrasound detected tendinitis in 9 extensor tendons and MRI detected tendinitis in 8 tendons.Conclusion
We found a significant correlation between power Doppler ultrasonography and MRI in the detection of signs of inflammation and bone destruction in the wrist and hand joints in rheumatoid arthritis, which raise the potential importance of power Doppler study in the assessment and monitoring of disease activity as a reliable non-invasive method. 相似文献12.

Introduction
Radiographic findings of the shoulder joint have been reported in patients with rotator cuff tear, greater tuberosity changes are among the most reported.The aim of this work is to assess the greater tuberosity sclerosis as a radiographic sign of rotator cuff tear and its relation to the tear size.Patients and methods
This study was conducted from July 2009 until May 2013 in a retrospective fashion and included 425 patients, 250 females (58.8%) and 175 males (41.2%).Results
Sclerosis was detected in 398 cases out of 425 patients (93.6%). Of those, 360 (90%) were found to have a tear of the rotator cuff documented on M.R.I. Also greater tuberosity sclerosis being more prominent with large-sized tears. One hundred (23.5%) patients had been operated arthroscopically and a tear documented intraoperatively (Table 2).Conclusion
Greater tuberosity sclerosis has both high sensitivity and positive predictive value for rotator cuff tear. Also greater tuberosity sclerosis is found more with large-sized rotator cuff tears. 相似文献13.

Purpose
Evaluate MDCT findings in patients with blunt chest trauma with a demographic evaluation of number and percentage of each pattern over 6?months at University Hospital.Patients and methods
This study involved 125 patients, including 90 males and 35 females with a mean age of 51.4?years. They were exposed to blunt chest trauma and were referred to the emergency radiology department. All patients were subjected to clinical examinations with medical history interview, plain chest X-ray, and MDCT of the chest with 3D reconstruction.Results
Road traffic accidents were the most common mechanism of trauma, accounting for 56.8% of the 125 cases. Chest pain was the most common clinical presentation, observed in 76%. Both sides of the body were affected in 41.6%; the right side was affected in 29.6%; and the left side was affected in 28.8%. Radiological findings among the patients in the order of frequency were pleural injuries in 72% of the patients, parenchymal lung injuries in 56.8%, chest wall injuries in 40.8%, mediastinal injuries in 11.2%, diaphragmatic injuries in 4.8% and tracheo-bronchial injuries in 1.6% of the patients.Conclusion
Chest trauma may cause significant morbidity, and MDCT could lead to critical changes in a patient's management. 相似文献14.

Background
The systematic use of MDCT angiography in patients with haemoptysis is especially helpful to identify ectopic bronchial arteries, non-bronchial systemic arteries and pulmonary artery pseudoaneurysms.Aim of this study
Aim of this study is to assess the role of MDCT angiography in the evaluation of abnormal bronchopulmonary vasculature in patients with haemoptysis.Results
The study was performed on 36 patients presented with haemoptysis and showing vascular abnormalities on CT angiography. Tuberculosis was the most common underlying disease. Dilated bronchial arteries (BAs) were detected in 86% of patients; they originate between D4 and D6 vertebral levels. About 95% of right BAs have their ostia between 9 and 10o’clock positions, while 75% of left BAs originated between 11 and 1o’clock positions. This study included 8 non bronchial systemic arteries with the inferior phrenic arteries were the most common. Significant pleural thickening (>3?mm) may predict non-bronchial arterial supply. Pulmonary arteries had a role in haemoptysis in only 2 patients.Conclusion
This study has shown that MDCT angiography is a valuable non invasive diagnostic tool in the evaluation of haemoptysis. It provides a roadmap of the vascular abnormalities and aids in the diagnosis of the underlying disease. 相似文献15.

Purpose
Is to compare the role of 128 MDCT in quantitative evaluation of left ventricle function in patients with coronary artery disease compared to 2D echocardiography.Patients and methods
Fifty patients with suspected coronary artery disease underwent contrast enhanced MDCT using retrospective gating without dose modulation. Ten phases of cardiac cycle were processed to assess end-systolic and end-diastolic phase at LV short-axis view. 2DSE was performed in the same day. LVSV, LVDV, LFEF, LVSV were calculated using the Simpson's method in MDCT and modified Simpson's method in echocardiography.Results
LVSV, LVDV, LVSV, LFEF were 74.30?±?24.92, 185.46?±?56.25, 84.15?±?33.16, 48.88?±?13.32 respectively on MSCT and 71.43?±?21.93, 182.31?±?56.49, 81.74?±?32.88, 47.82?±?13.64 respectively on echocardiography with excellent correlation between the modalities (P?<?0.001) using linear regression analysis. A Bland-Altman analysis showed that MDCT had slightly higher LVSV, LVDV, and LVSV, LFEF values with mean value of differences of 2.9, 3, 2.4 and 1% respectively.Conclusion
MDCT is an accurate method for quantitative evaluation of global left ventricular function compared to 2D echocardiography. 相似文献16.

Background
Conventional radiographs of the left wrist have been used for assessment of the skeletal age. However, radiation exposure, for this purpose has been considered invasive in the sporting environment.Aim
To study the reliability of MR imaging of the wrist for estimating bone age in Egyptian young male football players.Materials and methods
Sixty-one football players between 13 and 18-year-old were recruited. All of them had well known certified chronological age. Coronal Spin-echo T1-weighted images in 3?mm slices were obtained. Three independent raters assessed the degree of fusion of the left radius using a recently developed grading system, composed of six grades.Results
Moderate correlation between the MR skeletal age with the chronological age in Egyptian young male football players is noticed. Strong interobserver agreement about rating of grade of fusion by MRI has been shown. Moreover, we could build up a regression model for estimation of the players age from grade of fusion by MRI.Conclusion
Age determination by MR of the left wrist as a radiation - risk free tool provides moderate correlation with the chronological age. A reliable predictive rule for estimation of a player's age from grade of fusion by MRI could be achieved. 相似文献17.

Objective
The aim of this work is to highlight the diagnostic value of multidetector CT in assessment of gastric malignancy compared to surgical and pathological results.Method
A Multicenter study was conducted from (October 2011–March 2014). Thirty-five patients were included, eight females and twenty-seven males with mean age 50?years (34–81). All patients were subjected to; Full history taking and physical examination, Multidetector Computed Tomography (MDCT), and Upper Gastro intestinal endoscopy. Triphasic CT was used using oral and IV contrast where scanning at arterial phase cuts were taken after 15?s followed by portovenous 20–25?s after the arterial phase.Results
74% of Lesions detected at the study were mural thickening, with adenocarcinoma pathology. MDCT T staging compared to pathological staging was highly significant. Only 33 cases had pathological reports suitable for comparison with the MDCT staging. True positive cases were 30, false positive cases were 2 cases and false negative was only one case, Thus giving sensitivity 96.7% and accuracy 91%.Conclusion
Multidetector CT can play an important role in diagnosis and preoperative staging of gastric cancer. 相似文献18.

Objectives
Multi-detector computed tomography (MDCT) and cone beam computed tomography (CBCT) were compared regarding their ability to detect vertical root fractures.Methods
Sixty four extracted posterior teeth were included in this study. Using a diamond disc, thirty six teeth were cut vertically to simulate a VRF. Twenty eight teeth were used as control. Fractured and non-fractured teeth were randomly positioned in 4 skulls and mandibles. Scanning was performed first on a 16 slice Siemens MDCT, then by i-CAT Next Generation CBCT. Two observers assessed the multiplanar images for vertical root fractures using a 3-point scale. The first observer repeated the assessment after 1?week. Later, the 2 observers re-assessed the images together to reach a consensus score.Results
CBCT showed higher sensitivity, accuracy as well as negative predictive value compared to MDCT. The mean area under the curve was 0.917 for MDCT and 0.972 for CBCT. The difference in diagnostic accuracy between the 2 modalities was statistically significant P?=?.036. Inter-observer agreement was 0.971 for MDCT and 0.994 for CBCT, whereas intra-observer agreement was 0.981 for MDCT and 0.985 for CBCT.Conclusion
Using the specified scanners at the specified exposure parameters, the diagnostic accuracy of CBCT in detecting vertical root fractures was significantly higher than MDCT. 相似文献19.

Aim of work
To assess the role of color Doppler ultrasonography and multidetector computed tomography angiography (MDCTA) in diagnosis of uterine arteriovenous malformations (AVMs).Methodology
Twenty patients were referred to the radiodiagnosis and imaging department, faculty of medicine, Tanta University from obstetric and gynecology department. All patients were suspected clinically to have uterine arteriovenous malformations. All were subjected to history taking regarding clinical state, laboratory investigation and color Doppler ultrasonography and multidetector computed tomography angiography of the pelvis.Results
Color Doppler ultrasound sensitivity was 100% in detecting a uterine hypervascular lesion and highly suggesting the diagnosis of uterine AVM and the sensitivity of MDCT angiography was 100% in diagnosing and evaluating uterine AVM.Conclusion
Doppler US can strongly suggest the presence of AVM but patient should undergo CT angiography for definitive diagnosis and possible embolization, as CTA helps in providing valuable cross sectional anatomical details about the lesion, its extent and its surroundings. 相似文献20.
