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3.

Objectives
To create a systematic approach using computed tomography (CT) and magnetic resonance imaging (MRI) findings to facilitate identifying the etiology of hearing loss, evaluating the anatomy for surgery, and predicting complications.Methods
Twenty nine pediatric patients with congenital or acquired sensory-neural hearing loss (SNHL) requiring cochlear implant (CI) were included. They underwent combined CT, 3D DRIVE MRI axial plane and axial T2WIs for the whole brain. The inner ear, cochlear nerve development, temporal bone anatomy, operative window, normal variants and causes of central hearing loss were assessed.Results
CT showed that 100% of the patients are suitable for CI while MRI showed that 96.5% of studied patients are suitable. The examined ears were categorized into 4 groups according the candidacy for operation; 86.2% were suitable for CI, 5.1% were suitable for CI but with expected poor response, 1.7% of examined ears were suitable for CI with modification of surgical procedure and 6.8% were not suitable for CI.Conclusion
In Suez Canal area, the combined CT/MRI approach categorized the majority of patients with SNHL (96.6%) as good candidates for CI. 相似文献9.

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10.

Objective
To evaluate the use of diffusion tensor imaging (DTI) and fractional anisotropy (FA) as prognostic tools in anticipating the recovery of stroke patients.Patients and methods
40 patients were included in our study after exclusion of 23 patients. All patients admitted in Neurology Department with stroke. The patients subjected to National Institute of Health Stroke Scale (NIHSS) followed by MRI with DTI and FA calculation. Follow up after three months was done based on the Modified Rankin Score (MRS). The results were compared and statistically analyzed.Results
There was a statistical significant between the NIHSS and DTI pattern at the time of admission (p value?<?0.05) reflecting the severity of the stroke with 22 patients showed disrupted fibers (55%), of which 16 patients were categorized as moderate NIHSS and 19 patients showed poor outcome. Relative FA equal 0.8 was found to be the cut off value in predicting the poor or good prognosis using MRS as a reference with 94.4% sensitivity, 90.9% specificity and 0.833 area under curve.Conclusion
DTI is a prognostic tool in anticipating the recovery of the stroke patients. Moreover, the relative FA score works as more additive value in evaluation of the patient improvement. 相似文献11.

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12.

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13.

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14.

Objective
The aim of this study was to assess the ability of CT to predict the pathological nature of pancreatic cystic lesions if it is benign, malignant or premalignant.Methods
This is a retrospective study from the database of our hospital EMR (electronic medical records) for pancreatic lesions from patients who proven to be of pathological cystic nature. The diagnosis and characterization of pancreatic cysts were done by multislice 32 CT examination. We reviewed the data from the radiology, surgery and pathology departments from the period of November 2012 until January 2015. We compared between operative and pathological data and findings of MDCT using chi square test.Results
We reviewed the data from the radiology, surgery and pathology departments from the period of November 2012 until January 2015. The study was done on 66 patients. Our results showed that CT features for benign cystic lesions are lobulated shape and a thin wall (≤1?mm) while the round or oval shape or a complex cystic shape with tubular cyst and a thick wall (>1?mm) are more frequently seen in pancreatic premalignant and malignant macrocytic lesions.Conclusion
CT with thin section images allows adequate morphological characterization of macrocytic pancreatic masses that could predict its pathological nature if benign or malignant. 相似文献15.

Objective
The objective of the present study was to analyze the efficacy of 256-slice CT in differentiation between the perforated and non-perforated appendicitis.Subjects and methods
The study included 85 patients with acute appendicitis. Appendicectomy and pathological confirmation were done for 79 patients and classified into 44 patients with non-perforated appendix and other 35 patients with perforated appendix. The statistical analysis was performed using six CT findings (abscess formation, phlegmon, extraluminal air, extraluminal appendicolith, focal defect in the appendicular wall and inflammatory changes of the retroperitoneal space) individually and when combined together in five groups.Results
The sensitivity, specificity and accuracy of each CT finding were ranged between 20%–51%, 86–100% and 65–76% respectively. The PPV and NPV of these findings ranged between 75–100% and 61–70% respectively. Detection of any of these findings in combination of different groups resulted in raising of the sensitivity reaching between 71 and 97%.Conclusion
Multislice CT is considered the modality of choice for imaging of acute appendicitis, not only to confirm the diagnosis but also it plays an important role in assessment of appendicular complication, particularly in detection of perforated appendix. 相似文献16.

Objective
To assess whether the diaphragmatic and lung ultrasound (US) can be used as additive new parameters for the weaning process in intensive care units (ICU) patients in comparison to the traditional weaning parameters.Patients and methods
68 patients were included in our study. All patients admitted inside different ICU units-Ain Shams University for different causes mainly post major surgeries. All patients met the traditional criteria for weaning, had diaphragmatic and lung ultrasound after extubation. We measured the diaphragmatic excursion (E), diaphragmatic thickening fraction (DTF) as well as the degree of lung aeration. All US results were collected and compared with some of usual weaning parameters namely the arterial blood gases as well as respiratory mechanics. The results were statistically analyzed.Results
50 patients showed successful weaning process. Diaphragmatic E and TF showed high sensitivity and specificity in correlation with the other parameters. The cut off value was 10 mm for the E and 28% for the DTF and 12 for the lung US. A score was put to predict the outcome of weaning process.Conclusion
For the patients undergoing weaning process, diaphragmatic and lung ultrasound can be used as additive new parameters for prediction of weaning process outcome. 相似文献17.

Background
Currarino recognized a triad of congenital malformations of the hindgut and the sacrococcygeal spine as a distinct syndrome. A characteristic radiological sign described as scimitar sacrum is pathognomonic of the syndrome. A radiograph of the pelvis requested for some other reason may detect the typical scimitar detect in the lower sacrum and the coccyx.Case
We report a case of a ten year old girl with recurrent pre-sacral abscess in whom the diagnosis of Currarino syndrome was suspected on plain radiography and confirmed on CT/MRI. To the best of our knowledge this is the second case of Currarino Syndrome being diagnosed in a patient following presentation as a presacral abscess.Conclusion
The clinical features, unique radiologic appearance, and importance of a correct diagnosis of the Currarino triad are discussed which often requires inter-departmental cooperation for correct diagnosis and management. 相似文献18.
