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2.

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.

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10.

Objective
The aim of this study was to clarify the association between epicardial fat volume and coronary atherosclerosis.Materials and methods
A total of 90 patients with clinically suspected coronary artery disease underwent MDCT coronary angiography. The images were interpreted for Calcium score, quantification of epicardial adipose tissue (EAT) volume, and coronary artery disease (CAD) which was classified according to the number of affected vessels, location, extension, component of the lesion and degree of obstruction. EAT was correlated to CAD and Calcium score using 125?cm3 as a cutoff value for acceptable EAT volume.Results
The patients were classified into 3 groups: patients with 1-normal CCTA, 2-non-significant CAD and 3-significant CAD. A high statistical significant difference was found among the 3 groups regarding mean coronary calcium score (P value?=?0.00) and mean EAT volume; Group 1 (125.14?±?56.88?cm3), in group 2 (217.38?±?56.88?cm3) and the largest EAT volume was seen in group 3 (327.94?±?90.17?cm3), (P value: 0.00).Conclusion
The estimation of EAT volume could be considered as a screening test for any patients suspicious for CAD. 相似文献16.

Purpose
Is to compare the role of 128 MDCT in quantitative evaluation of left ventricle function in patients with coronary artery disease compared to 2D echocardiography.Patients and methods
Fifty patients with suspected coronary artery disease underwent contrast enhanced MDCT using retrospective gating without dose modulation. Ten phases of cardiac cycle were processed to assess end-systolic and end-diastolic phase at LV short-axis view. 2DSE was performed in the same day. LVSV, LVDV, LFEF, LVSV were calculated using the Simpson's method in MDCT and modified Simpson's method in echocardiography.Results
LVSV, LVDV, LVSV, LFEF were 74.30?±?24.92, 185.46?±?56.25, 84.15?±?33.16, 48.88?±?13.32 respectively on MSCT and 71.43?±?21.93, 182.31?±?56.49, 81.74?±?32.88, 47.82?±?13.64 respectively on echocardiography with excellent correlation between the modalities (P?<?0.001) using linear regression analysis. A Bland-Altman analysis showed that MDCT had slightly higher LVSV, LVDV, and LVSV, LFEF values with mean value of differences of 2.9, 3, 2.4 and 1% respectively.Conclusion
MDCT is an accurate method for quantitative evaluation of global left ventricular function compared to 2D echocardiography. 相似文献18.

Objectives
To evaluate the reliability of diffusion-weighted imaging (DWI) in evaluating kidney changes after extracorporeal shock wave lithotripsy (ESWL) treatment for kidney stones.Patients and methods
This prospective study included 28 patients who subjected to ESWL treatment for renal stones. Color Doppler ultrasonography (CDUS) and DWI were achieved before and within one day after ESWL. Follow up DWI also performed 2?weeks after ESWL. DWI was performed with b factors of 0, 500 and 1000?s/mm2 at 1.5?T MRI. For each patient, the Resistive index (RI) and ADC values were calculated for both the affected and contralateral kidneys.Results
The ADC values of the treated kidneys were lower in all three poles of the kidney compared with ADC values done before ESWL and in comparison with the contra lateral un-treated kidney. The RI showed no significant difference in the three poles of treated and untreated kidneys before and after with ESWL (p?>?0.05).Conclusion
DWI is a reliable method in detecting renal changes after ESWL treatment that can give prediction about kidney changes produced by shock waves. 相似文献20.
