Objectives
To evaluate accuracy of computed tomography angiography (CTA) in evaluation of post traumatic renal vascular injury.Patients and methods
38 patients were presented with post traumatic intermittent or persistent hematuria. Renal CTA and digital subtraction angiography (DSA) were done for all patients.Results
CTA demonstrated pseudoaneurysm (PA) in 30 patients (78.9%) and no vascular lesions in 8 patient (21.1%). CTA had 86.11% sensitivity and 50% specificity in detection of post traumatic renal pseudoaneurysms, CTA missed diagnosis of renal arteriovenous fistula (RAVF) in 10 patients which discovered later by DSA.Conclusion
CTA with MIP as non invasive technique widely replaced renal DSA in detection of posttraumatic renal pseudoaneurysm. Renal DSA is still best modality in detection of RAVF and also has the upper hand in planning of selective renal artery embolization for the management of persistent or delayed hemorrhage from renal vessels. 相似文献2.

Purpose
to evaluate the role of three dimentional power doppler ultrasonography (3D PDUS) of the uteroplacental circulation in early pregnancy as a screening tool for prediction of preeclampsia.Patients and methods
50 pregnant women who came to do routine ultrasound scan between 11 and 13.6?weeks of pregnancy during the period from February 2016 to April 2016. Placental volume and vascularization indices were obtained, and vascular index (VI), flow index (FI), blood vessels and blood flow index (VFI) were calculated by three-dimensional Doppler histogram.Results
Of the included 50 pregnant women, 22% developed preeclampsia and 78% did not develop preeclampsia. The placental blood flow perfusion in patients with pre-eclampsia had a lower VI, FI and VFI compared to non preeclamptic women with highly significant statistical difference (P?<?0.001)Conclusion
3D PDUS can be used as an effective screening tool to predict preeclampsia in early pregnancy. 相似文献5.

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7.

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8.

Aim
To evaluate the role of MRI in detecting possible causes of incontinence in patients with anorectal malformations after the initial corrective surgery.Materials and methods
The study included 17 patients; age ranged from 1 to 18?years. T1 and T2 weighted images were obtained in axial, coronal and sagittal planes, sequences were obtained without fat saturation to easily identify low signal muscles against high signal fat.Results
MRI accurately assessed the grade of development of sphincter muscles; muscles graded as good in 4 patients, fair in 2 patients, poor in 5 patients and 3 cases had asymmetrical muscles. The position of pulled through bowel was laterally mislocated to the left side of the sphincter muscles in 2 cases and was anteriorly mislocated in 5 cases. Inadvertently placed mesenteric fat around the pulled through bowel was depicted in 10 out of 17 patients. Associated anomalies of the vertebral column, spinal cord and urogenital system was depicted in 11 patients. One case had classical caudal regression syndrome.Conclusion
MRI is very useful in the postoperative assessment in patients with anorectal malformations. It plays an important role in diagnosis of possible causes of incontinence, postoperative complications and detecting associated anomalies in one study. 相似文献10.

Objective
The goal of this study was to highlight the role of follow up CT angiography examination in detection and classification of endoleaks and therefore deciding management plans after endovascular abdominal aortic aneurysm repair (EVAR).Patients and Methods
During one year duration 37 patients who have been operated were examined 1 and 6 months after EVAR as routine follow up. The images obtained were interpreted and reconstructed using dedicated software and work stations.Results
Out of 37 cases, 14 cases (37.8%) had positive endoleaks and 23 cases (62.2%) were free. Type I endoleak was diagnosed in 4 cases (10.8%) and type II endoleaks was diagnosed in 10 cases (27%) as 7 cases (18.9%) showed leak through lumbar arteries and 3 cases (8.1%) showed leak through the inferior mesenteric arteries.Conclusion
CT angiography can accurately detect and classify endoleaks and thus determine line of treatment. Endoleaks are often asymptomatic and may become evident intra operatively or many years after the operation, therefore lifelong imaging supervision is necessary. 相似文献13.

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14.

Objective
To compare the accuracy of 2D and 3D CT measurements of femoral anteversion angle, in pediatric patients with developmental hip dysplasia.Materials and methods
Twenty patients (20 hips) with unilateral non syndromic DDH were studies. CT scans were performed using a 16 slice CT scanner to measure the femoral anteversion angle (FAVA) using 2D & 3D techniques. Findings were correlated with the intra operative measurements.Results
There was a significant difference between 2D & 3D methods. Results of clinical assessment were comparable to results of 3D CT assessment which range from 30 to 50° with a mean of 37.5°. Mean percent difference between 3D and intra operative measurement of FAVA was significantly lower than the corresponding value between 2D and intraoperative measurement of FAVA.Conclusion
3D is more accurate than 2D in measuring the degree of FAVA in DDH patients. It is easily applied and rapid and doesn't require sophisticated software. 相似文献15.

Objective
The aim of this study was to assess the role of multislice computed tomography (MSCT) using 2D and 3D images in evaluation of different types of Le Fort fractures.Subjects and methods
30 cases referred from the Emergency unit in Zagazig University Hospital were included in this study, based on clinical evidence of facial trauma, they underwent multislice computed tomography (MSCT) examination and were shown to be positive for pterygoid fractures.All patients subjected to non contrast MSCT in axial cuts. Multiplanar reformatted (MPR) images were acquired using the machine software in sagittal and coronal planes. Finally images were transferred to a workstation for reconstruction of 3D images.Results
Sensitivity of multislice computed tomography (MSCT) in detecting compound Le Fort fractures for radiologists A, B and C was 94.4%, 66.7% and 100% respectively. Sensitivity of MSCT in detecting isolated Le Fort fractures for radiologists A, B and C was 100%. The difference between radiologists A, B and C in detecting Le Fort fractures types was insignificant. Good agreement between radiologists A, B, C and intraoperative findings.Conclusion
Both 2D-CT and 3D-CT are the best methods in imaging of Le Fort fractures. 相似文献16.

Objective
Vaginal or uterine outlet obstruction leads to hematocolpos or hematometra. Detection of the etiology of this entity is important to guide adequate surgical management and thereby avoid complications and to preserve fertility. The aim of this study was to evaluate obstructing vaginal malformations in adolescent girls presenting with hematocolpos or hematometra with MR imaging.Materials and methods
A hospital based prospective study was conducted in a tertiary care centre from September 2015 to October 2016. The study included 17 adolescent females who were evaluated with MRI.Result
Of 17 adolescent female with vaginal or uterine outflow obstructive anomalies with hematocolpos or hematometra, where 6 patients (35.3%) had HWWS, 6 patients (35.3%) had imperforate hymen, 2 patients (11.8%) had transverse vaginal septum, 1 patient each (5.9%) had cervico-vaginal atresia, unicornuate uterus and communicating rudimentary Uterine horn. MRI revealed hematocolpos in 15 patients (88.2%), hematometra in 13 patients (76.5%), endometriotic ovarian cysts in 6 patients (35.3%) and hematosalpnix in 3 patients (17.6%).Conclusion
Early radiological diagnosis of the cause of vaginal or uterine outflow obstruction is important to guide adequate surgical management which if undertaken promptly helps to avoid complications due to reflux from vaginal or uterine outflow obstruction. 相似文献17.

Objective
to establish the role of transthoracic ultrasound as a bed-side, available, and affordable technique for imaging chest trauma patients and compared its sensitivity, specificity and accuracy for detecting chest trauma sequelae and complications to those of CT.Patients and methods
This study included 107 cases. All patients had chest trauma or polytrauma with chest involvement. Transthoracic ultrasound and MSCT of the chest were evaluated. The results were assessed and compared by statistical analysis.Results
Of the injuries, 13.1% were penetrating, and 86.9% were blunt trauma. With CT as the standard, the most common injury US detected injury was pleural in 60.7% of patients, with diagnostic accuracy of 93.4%. Parenchymal lesions were found in 39.3% of patients with a 64.4% US diagnostic accuracy. Chest wall lesions were found in 15.9% of patients with an 89.7% accuracy, and mediastinal lesions were detected in 9.3% with a 94.3% accuracy.Conclusion
Chest ultrasonography has significant value for diagnosing complications of blunt and penetrating chest trauma with acceptable sensitivity and high specificity, particularly for pleural lesions and rib fractures. Ultrasound overcomes the difficulties involved in radiological examinations of small children and uncooperative patients. 相似文献18.

Objective
A comparative study of manual and automated post processing software tools to measure CT parameters before Transcatheter Aortic Valve Implantation (TAVI).Patients and methods
51 patients were included; all admitted to the Cardiology Department with clinically established severe aortic stenosis, in whom TAVI was the treatment of choice. All patients underwent CT angiography (CTA) pre-TAVI. The CT images were post processed and the needed CT parameters were calculated using both manual and automated methods. The results were compared for statistical analysis.Results
Only 43 patients completed the study, with mean age 65?years old. The automated software provided accurate almost similar results as the manual method, especially for aortic annulus area and aortic circumference measurements (p-value?=?1 and 0.548) and was accepted for left and right coronary artery ostium height (p-value?=?0.191 and 0.635).However, there was a statistically significant difference for the minor diameter axis and mean annular diameter (p-value?=?0.001 and 0.021).Conclusion
The automated software introduced rapid, accurate and reliable measurements for the aortic annulus in cases prepared for TAVI and can be used as a standard method. Also, it can be performed by junior staff with avoidable human errors. 相似文献19.
