Purpose
To investigate the value and highlight the role of multi slice computed tomography (MSCT) angiography in evaluation of extra-cardiac intra thoracic vascular anomalies in children.Patients and methods
This study included 24 patients (13 males and 11 females) with an age range of 1 month–13 years. All of these patients were clinically diagnosed to have congenital heart disease with suspected extracardiac vascular anomalies. All underwent prospective ECG-gated MSCT angiography after trans-thoracic echocardiography (TTE). Iterative reconstruction techniques were applied to reduce the radiation dose in MSCT angiography with the mean radiation dose of (4 mSv). The diagnostic accuracy and sensitivity of MSCT angiography and TTE were compared in comparison with surgical outcome.Results
The most common congenital extra cardiac vascular anomalies are PDA (45.8%) and aortic coarctation (37.5%). The major CT angiographic findings missed by TTE were coronary artery anomalies, absence of a pulmonary artery and pulmonary artery stenosis. The overall sensitivity of the MSCT angiography in diagnosis of the extra-cardiac vascular anomalies was 98.1% which was higher than that of TTE 80%.Conclusion
CG gated MSCT angiography is an accurate modality for demonstrating extra cardiac structures in complex CHD. It provides important complementary information to TTE with regard to extra cardiac vascular structures and coronary artery anatomy. This modality may reduce the need for high radiation dose invasive diagnostic cardiac catheterization. 相似文献2.

Objective
The aim of this study was to monitor the incidence of complicated inferior vena cava (IVC) anomalies and evaluate the role of Multidetector Computed Tomographic Venography (MDCTV) in diagnosis and assessment of associated venous collaterals, lower limb deep venous thrombosis (DVT) or varicose veins (VV).Patients and methods
During two years duration 100 patients with clinical history and complains suggesting of DVT or VV were prospectively evaluated after performance of MDCTV examination. The images obtained were interpreted and reconstructed using dedicated software and work stations. Results were correlated with Color Doppler Ultrasound (CDUS) findings.Results
Out of 100 cases, 9 cases (9%) were diagnosed to have complicated IVC anomalies while 91 cases (91%) had either well developed IVC or common anatomical variations. 6 cases (66.7%) had complicated IVC anomalies and 3 cases (33.3%) had associated complicated common iliac veins (CIV) anomalies. 8 cases (88.9%) had associated DVT and all cases (100%) had bilateral VV. 2 cases (22.2%) had associated varicocele and 1 case (11.1%) had associated KILT syndrome.Conclusion
MDCT venography examination has a major role in diagnosis of complicated IVC anomalies and detection of associated venous collaterals, lower limb DVT or VV. 相似文献3.

Purpose
Evaluate role of MRI and TRICKS-MR angiography in diagnosis of facial vascular anomalies.Material and methods
This study included 22 patients (mean age 9?years) with proved facial vascular anomalies on basis of interventional/surgical procedures (n?=?19) or clinical follow up (n?=?3). They underwent MRI examination with TRICKS-MRA. Images were evaluated for lesion location, size, feeding arteries and draining veins.Results
AVM was diagnosed in 15 patients (68.2%), hemangioma (5) patients (27.7%) and low flow venous malformation (2) patients (9.1%). TRICKS-MRA was accurate in diagnosis of 25 feeding arteries out of total 27 included in the study with 92.6% positive predictive value, 100% negative predictive value and 93.1% accuracy. AVMs were treated with sclerotherapy (26.7%), embolization (40%) and combined embolization and surgery (33.3%). Surgery was done in 2 hemangiomas (40%) while the other three patients (60%) underwent clinical follow up for 2?years with stationary course. The 2 patients with venous malformation underwent successful sclerotherapy.Conclusion
MRI & TRICKS-MRA provide excellent diagnostic data for assessment of facial vascular anomalies. TRICKS -MRA adds precise delineation of the vascular mapping, regarding feeding arteries and draining veins which helps in planning of therapeutic approach and reduces needing for invasive DSA. 相似文献5.

Objective
We evaluated multidetector computed tomography (MDCT) accuracy for the prediction of the optimal prosthetic aortic valve deployment angle in trans-catheter aortic valve implantation (TAVI) with the different variables.Methods
Sixty-six patients underwent contrast-enhanced MDCT before TAVI. From the three-dimensional aortic root reconstructions, we get the appropriate perpendicular aortic valve projection at which the bases of the aortic valve cusps were on a straight line. The predicted angles by MDCT were compared to the perpendicular fluoroscopic angles of the prosthetic valve. The degree of MDCT accuracy was defined as accurate, suitable or inaccurate according to the difference between the predicted angles and the perpendicular prosthetic valve projections. The degree of aortic cusp calcification, annular ellipticity, the type of aortic valve (to be tricuspid or bicuspid), were compared in patients with accurate, suitable and inaccurate prediction. The radiation exposure and volume of the used contrast agent were also considered in the comparison.Results
MDCT prediction was accurate in 84.8% of cases, suitable in 9.1% and inaccurate in 6.1% of cases. There was a significant association between MDCT accuracy and the valve type with higher rates of accurate prediction with tricuspid aortic valves than bicuspid valves (93.1% versus 25%, respectively). The mean number of aortograms and the volume of contrast agent used for TAVI procedure were significantly less in patients with accurate CT prediction (p < 0.001).Conclusion
MDCT allows accurate prediction of the proper deployment angle for TAVI. Bicuspid aortic valve is significantly associated with fewer rates of accurate prediction. 相似文献8.

Purpose
To evaluate the role of non-contrast multidetector CT (MDCT) reliability in localizing CSF leaks and skull base defects in correlation to operative findings.Materials and methods
Twenty patients clinically diagnosed to have CSF rhinorrhea; 8 spontaneous and 12 post-traumatic patients were evaluated using 64-rows MDCT with slice section 0.6 mm. CT is considered accurate if correctly determine the site and size of bony defect as matched with operative findings.Results
MDCT accurately detected the site of presumed CSF leak in 19 out of 20 cases with sensitivity 95%. Cribriform plate defect is the most common site of defect in 40% of cases with 75% of cases categorized as Keros type II. The consensus image with fair agreement (K = 0.38) shows that coronal reformat has the highest diagnostic performance in 75% of cases while the least diagnostic value is encountered with the axial plane in 15% of cases (p = 0.095). There is almost a perfect agreement (K = 0.810) between the MDCT measurements and operative size of bony defect with minimal difference in 10% of patients (P < 0.001).Conclusion
Non-contrast MDCT is an accurate reliable non-invasive imaging modality for preoperative evaluation of CSF rhinorrhea. 相似文献9.

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10.

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11.

Background
Urinary tract injuries occur in 3–10% of abdominal trauma. Early recognition and diagnosis of ruptured bladder is essential to lower this mortality rate. CT is the method of choice for the evaluation of patients with blunt or penetrating abdominal and/or pelvic trauma. Imaging in patients with suspected bladder injury with CT cystography may be performed using either an intravenous or retrograde technique.Aim of work
The aim was to evaluate the role of CT in diagnosing traumatic urinary bladder injuries.Materials and methods
The study was carried out on 32 patients with suspected traumatic urinary bladder injury. All patients were subjected to contrast-enhanced CT study and classified according to Sandler et al. classification of urinary bladder injuries.Results
All patients were classified according to the type of the encountered urinary bladder trauma. Type I injury was diagnosed in 3.1% of patients, type II in 18.8%, type III in 3.1%, type IVa in 12.5%, type IVb in 43.7% and type V in 18.8%. 21.8% of patients were managed conservatively, while 78.2% of patients underwent surgical repair.Conclusion
CECT well demonstrated traumatic urinary bladder injuries. 相似文献12.

Background
Ninety percent of hepatic cancers are hepatocellular carcinomas (HCC) which have an unfavorable prognosis. HCC is a hypervascular tumor supplied mainly by the hepatic artery. It has a higher blood supply than the surrounding hepatic tissue due to neovascularization. Computed tomography with perfusion imaging (CTP) is a non invasive tool which quantifies the blood flow parameters of HCC and compares it to the surrounding tissue.Purpose
To prove that CTP is a valuable diagnostic tool in diagnosis of HCC and posttherapeutic assessment.Patients and methods
One hundred and twenty-six HCC patients with 150 focal lesions are enrolled this study. Perfusion parameters are quantified and results are compared to those of triphasic CT.Results
CTP detected 141 lesions with 94% sensitivity and 40% specificity with elevated arterial perfusion (AP) and perfusion index (PI) with low portal flow (PF). It missed 5 lesions because of their hypovascularity and 4 lesions following radiofrequency ablation (RFA) and trans arterial chemo embolization (TACE).Conclusion
CTP is a safe and specific imaging tool for diagnosis and assessment of therapeutic interventional procedures in HCC. 相似文献15.

Aim of the study
Our study is a prospective study aiming to assess congenital bicuspid aortic valve using cardiac MRI and to detect a relationship between the leaflet fusion pattern and other functional parameters including valvular regurge, stenosis and pressure gradient.Patients and methods
This prospective study included 114 cases 104 of them had bicuspid aortic valve, diagnosed by echocardiography while the rest (10 cases) were normal control cases. All functional and morphological cardiovascular abnormalities were recorded as well as any associated congenital diseases. Two different radiologists read the MRI blindly to each other.Results
Patients age ranged from 40?days up to 20?years with 62 patients being in the pediatric age group (<12?years). They were 78males and 26 females.We found 54 cases (53.8%) of 1-RL morphology, 34 cases (32.7%) of 1-RN morphology, 8 cases (7.7%) of 0-AP and 6 cases (5.8%) of 0-Lateral. Aortic stenosis and regurgitation were found in 80.75% of cases. Aortic stenosis was the most common valvular lesion being more evident in the 1-RN valve type. Aortic regurge was more predominant in the pediatric age group with no predilection for a specific valve phenotype. Left ventricular function was normal in most of our cases with only 10 cases showing impairment due to long standing valvular lesion.Thirty-eight cases (36.5%) had associated aortic dilatation. Twenty-six patients (25%) showed associated aortic coarctation. Intra cardiac shunts (24 patients 23%) were the second most common associated anomaly after coarctation. Most of the associated congenital anomalies were found with the 1-RL valve morphology type. Other associated congenital anomalies were detected in 44 patients (42.3%).Conclusion
Cardiac Magnetic resonance should be performed for patients with bicuspid aortic valve to determine the valve phenotype, function and aortopathy for risk stratification and surgical management. Patients with RL type should be properly imaged to detect associated congenital anomalies. 相似文献17.

Objective
To assess the diagnostic accuracy of diffusion weighted imaging (DWI-MRI) being a non-contrast based MR sequence versus dynamic contrast enhanced MRI (DCE-MRI) in the preoperative loco-regional staging of the cervical carcinoma.Methodology
Fifty cases of proved cancer cervix prior staging subjected to dynamic post contrast technique: one pre-and six post contrast phases (40?s each). DWI was scanned using different b values and ADC values were measured.Results
DWI was the most accurate in staging operable cases (93.3%).Parametrial infiltration was overestimated in 3 cases versus 4 cases in DCE-MR. DWI showed 100% sensitivity, positive predictive value and accuracy in the assessment of locally advanced carcinomas. In metastatic lymph nodes, DCE-MR showed the least accuracy of 86%.Conclusion
DWI is helpful in discriminating local from locally advanced cervical carcinomas. DCE-MR can delineate cervical carcinomas confined to the uterus and exclude bladder/rectal invasion. 相似文献19.
