Background and objective
Laparoscopic sleeve gastrectomy become widely employed and accepted operation in between Arab population as a permanent solution for morbid obesity. There are many acute complications associated with LSG such postoperative leaks or bleeding, abscess formation, splenic infarction and portal vein thrombosis. The purpose of the study is to present how multidetector CT is beneficial as a screening investigation to detect these complications.Methods
We retrospectively review CT images done in the first week post operative for280 patients subjected to LSG the center in the period between July 2017-December 2017 (average age 39.5?years old).Results
the leak was suspected in 3 patients documented by a direct leak of contrast in one of them, 2 patients active bleeding was clinically suspected, but the exact site of bleeding could not be identified by CT, 15 patients had serous fluid collection, splenic infarction was noticed in 18 patients, 3 patients developed postoperative hematoma one of them become infected, anterior abdominal wall hematoma seen in 5 patients, one patient developed portal vein thrombosis.Conclusion
CT is an important imaging tool to diagnose post LSG complications. 相似文献2.

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6.

Purpose
To analyze the diagnostic value of multi-detector CT enterography (MDCTE) in identifying small bowel causes of acute non traumatic abdominal pain and in determining the extent of bowel lesion.Patients and methods
A total of 73 patients (42 males and 31 females aged from 12 to 85?years) who presented with acute non traumatic abdominal pain and were evaluated with computed tomography enterography (MDCTE) between August 2014 and July 2017 were enrolled in the study. The diagnostic value of MDCTE was analyzed by using the results of other imaging modalities, endoscopy, surgery, pathology and clinical follow-up as the reference standards.Results
MDCTE correctly made the diagnosis in 66 of 73 patients (true positive), 7 cases were missed by CTE findings (false negative cases) and one case of ileus was falsely diagnosed as small bowel obstruction with an overall sensitivity of 90%, specificity?=?93%, PPV?=?98%, NPV?=?71%. The diagnostic accuracy of each CT sign was calculated independently for each underlying etiology.Conclusion
The use of MDCTE may be of significant value in identifying the cause of acute abdominal pain of small bowel etiology, in determining disease activity in inflammatory causes and identifying the level and cause of obstruction in SBO. 相似文献7.

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8.

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10.

Objective
To evaluate the outcome and the cost value of surgical clips use as guidance for breast cancer localization in patients prepared for neoadjuvant chemotherapy (NAC).Methods
A prospective study of 43 patients confirmed histopathologically to have breast cancer and prepared to receive pre-operative NAC. Surgical clips were inserted via US guidance. The patients were followed up by mammography and US before surgery to evaluate the treatment response meanwhile, assessment of clips location, migration and complications. The overall cost of clips was also calculated.Results
Only 32 patients completed the study; the mean time interval was 32?weeks?±?2?weeks between the clip insertion date and the surgery. The number of the inserted clips was 34 surgical clips. Only two cases showed positive migration yet with no evidence of other complications occurred in our study patients. The average cost of the surgical clips was 145?±?20 Egyptian pounds (average 8–9 US$).Conclusion
Surgical clips can be used safely to replace the usual commercial markers in the localization of breast cancer before NAC. They showed effective results with no complications, don't interfere with the patients' imaging and of the significant low cost compared to the commercial ones. 相似文献12.

Background
Multiple sclerosis (MS) is a chronic disease with a wide range of pathologic changes that modify the apparent diffusion coefficient (ADC) value.Patients & methods
A prospective study included Forty two MS patients, underwent conventional and diffusion weighted MR imaging with ADC measurement in plaques and normally appearing white matter (NAWM), compared with normal white matter (NWM) of a control group (n?=?21). They were followed-up six months later.Results
Significantly higher ADC values were found in acute and secondary progressive cases than relapsing remitting (RR) cases and all values were higher than in normal white matter. A higher ADC values was found in NAWM than control cases and in the newly developed plaques relative to old plaques in all types. A cut off ADC value 1.02?±?0.20?×?10?3?mm2/sec was detected for MS diagnosis, a value 1.41?±?0.10?×?10?3?mm2/sec to separate between acute and chronic RR cases and 1.2?±?0.10?×?10?3?mm2/sec to differentiate chronic sub-types.Conclusion
ADC value has the validity in diagnosis and follow-up of MS patients with different clinical sub-types. 相似文献15.

Purpose
To evaluate the role of 3-dimensional (3DUS) and 4-dimensional ultrasound (4DUS) in detection of fetal causes of oligohydraminos.Patients and methods
250 pregnant females (Age range from 19 to 45?years, mean age 33?years) were referred from the Obstetrics and Gynecology Department with oligohydraminos for fetal anomaly scan and Doppler study.Results
111 of the 250 patients were primi- gravida and 139 were multigravida. Consanguinity was positive in 106 females. In 100 patients, the examined fetuses were abnormal, TORCH infection was +ve in 25 patients. In 150 cases no fetal cause was detected for oligohydraminos. Autosomal recessive polycystic kidney disease (ARPKD, Potter type I) was the commonest fetal cause in our group detected in 24 of 100 patients followed by bilateral multicystic dysplastic kidney (Potter type II) in 19 patients, unilateral renal aplasia was the least cause in our study.Conclusion
3-dimensional and 4-imensional ultrasound and anomaly scan are effective in detecting fetal causes of oligohydraminos and early determination of lethal causes. 相似文献16.

Background
Assessment of treatment response in patients with a brain tumor is paramount, as true tumor recurrence and radiation necrosis are similar looking on conventional MRI.Purpose
To evaluate the role of dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging in the differentiation between recurrent brain tumors and radiation necrosis.Material and Methods
Twenty patients with a history of operated primary brain tumors and postoperative radiotherapy with or without chemotherapy were enrolled in this prospective study having conventional MRI findings of enhancing lesion suspicious of being recurrence or radiation necrosis. All patients were examined by DSC-perfusion MRI. Definitive diagnosis was reached through either subsequent surgical biopsy or follow up over 6-12 months.Results
Fifteen patients (75%) were diagnosed as tumor recurrence and 5 patients as radiation necrosis (25%). The relative cerebral blood volume (rCBV) and relative peak height (rPH) were significantly higher (P?<?0.05) in recurrent tumors than in radiation necrosis lesions. The rCBV and rPH thresholds in differentiating between them were 1.8 and 1.22 respectively with 87%, 93% sensitivity and 100% specificity for each respectively.Conclusions
DSC-perfusion MRI is a valuable non-invasive tool besides conventional MRI whenever available to differentiate between radiation injury changes and tumor recurrence. 相似文献20.
