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.

Aim and objectives
To assess the added value of hybrid FDG PET/CT in evaluation of extranodal lymphoma.Methodology
In this study, PET/CT was done for 50 patients with lymphoma; (36 NHL and 14 HD), to evaluate its value over CT alone in detecting extranodal extension.Results
The commonest extranodal sites affected by lymphomatous infiltration are in the following order: lung, bone, bone marrow, spleen, liver, GIT, head and neck, pleura, cutaneous tissue, peritoneum, brain, muscle and pancreas. Regarding the final outcome of the reviewed 77 extranodal lesions: depending on the criteria accepted as standard reference including histopathological results, clinical or radiological follow up, CT defined 66 (85.7%) studies as positive and 11 (14.3%) as negative. While PET/CT defined 71 (92.2%) studies as positive and 6 (7.8%) as negative. Most of the disagreement between both modalities (PET/CT and CT) could be detected among splenic, bone and bone marrow lesions. PET/CT was more sensitive and specific than CT alone in detecting extranodal lesions with sensitivity 97.22% and specificity 80%.Conclusion
PET/CT is superior over CT alone in detecting extranodal extension especially among splenic, bone and bone marrow lesions. 相似文献4.

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5.

Aim
Assessment of the clinical benefit of [18F]-FDG PET/CT examinations in restaging of patients with non Hodgkin lymphoma (NHL) in Egypt.Patients, methods
This study was performed on 45 patients with NHL. PET-CT and CECT were analyzed after end of chemotherapy regimen, using 12?months follow-up as standard of reference.Results
Follow-up of patients with NHL after 12?months of treatment revealed significant differences between staging by CT versus PET/CT (P?=?0.0001). Disease was upstaged by PET/CT in 36% (mostly in stages I and II) and downstaged in only 2% of patients. Agreement between PET-CT & CECT were usually in stage III and IV. Evaluation showed a sensitivity of 77% for CT alone, 95% for FDG-PET-CT.Conclusion
FDG PET-CT significantly improved sensitivity and specificity in restaging of NHL and therefore should be used routinely in follow up of patients with lymphoma. 相似文献6.

Background and aim of study
Spleen is the largest lymphoid organ on the human body, it has a very important immunological functions. Portal hypertension accompanied liver cirrhosis commonly leads to splenomegaly which may be complicated by hypersplenism. Also liver cirrhosis is frequently associated with decreased hematological indices with subsequent anemia, thrombocytopenia and leucopenia. Spontaneous bleeding can delay any surgical or endovascular intervention. Leucopenia with decreased immunity may interfere with treatment of cancer patients using chemotherapy. The objective of this prospective study is to achieve the maximum splenic tissue infarction with the least possible complications by performing partial splenic artery embolization in cases of hypersplenism through comparing two materials; gel foam in one group and microspheres in another group.Patients and methods
The study was conducted from October 2014 to September 2015. Thirty patients included in this study were presented by hypersplenism. They were 14 males and 16 females with mean age of 51?years. All patients were subjected to full history taking, clinical examination, laboratory investigations, pelvi-abdominal US and interventional procedure (transcatheter partial splenic artery embolization). The patients were divided into two groups, group (1): Fifteen patients were subjected to partial splenic embolization (PSE) using gel foam, group (2): Fifteen patients were subjected to partial splenic embolization (PSE) using microspheres.Results
Multiple complications appeared after the procedure some of them were of minor importance as post embolization syndrome (fever, pain and nausea) that continued for two days and disappeared in five patients. Haematemesis occurred in one patient of the first group. One case in the first group showed abscess formation after the procedure and this patient underwent the procedure using gel foam particles, four cases showed portal vein thrombosis, two in each group, Pleural effusion appeared in two patients of first group. Regarding the efficacy of the procedure, improvement in laboratory tests were nearly the same in both groups. However, regarding the occurrence of serious complications, the microsphere particles group show fewer complications than gel foam group.Conclusion
PSE using gel foam or microsphere showed nearly the same efficacy with no significant difference between the improvement in laboratory tests. However, using microsphere particles was associated with fewer occurrences of serious complications when compared with using gel foam. 相似文献8.

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13.

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

Aim
To evaluate the value of 18F-FDG (positron emission tomography) PET/CT in assessment patients with fever of unknown origin (FUO) and to compare the findings with the results of the other investigations.Patients and methods
This is perspective study in which 27 patients having FUO underwent 18F-FDG-PET/CT examination, using combined PET/CT with contrast enhanced CT. PET/CT findings were compared with the results of biopsies, immunology, or microbiology around the examination period & for the following 3 month duration, during which patients with negative PET/CT findings were followed also.Results
The cause of FUO was explained according to the PET/CT findings and the other investigations in 27 patients: 6 patients with infections, 2 patients with autoimmune inflammation, 3 patients with solid malignancies, 2 patients with sarcoidosis, 6 patients with vasculitis, 5 patients with lymphoproliferative disease & 3 patients with negative findings. PET/CT findings matched the clinical diagnosis in 23 patients, 4 patients showed negative PET/CT findings (2 patients as true negative & the other 2 patients as false negative that were fatherly diagnosed as lymphoma). The examination sensitivity 95%, specificity 67%.Conclusion
18F-FDG PET/CT can be a useful tool for scanning the whole body to suggest the FUO cause. 相似文献16.

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17.

Objective
This topic is concerned with the clarification of the radiological findings that should be reported as regard the anatomic variations of the neural structures related to the pterygoid process in patients listed for endoscopic sinus surgery.Materials and methods
This retrospective study included 164 patients who underwent multislice CT scan on paranasal sinuses in the Diagnostic Radiology Department in the period from February 2017 to December 2017. The pattern of pterygoid process pneumatization was evaluated. The anatomic variations of related neural structures were recorded.Results
The study included 164 patients with 328 pterygoid processes. The process was unpneumatized in 38.4% and pneumatized in 61.6%. Vidian canal type 1 was found in 7.3%, type 2 in 61.6% and type 3 in 31.1%. The incidence of foramen rotundum protrusion was higher with pneumatized processes, yet no statistically significant association was found.Conclusion
The neural structures related to the pterygoid process are the seat of many anatomic variations that need to be identified by preoperative CT. 相似文献18.

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.
