Role of 320 detector row CT perfusion in assessment of myocardial perfusion

Aim of the work: this study aimed to evaluate the coronary artery morphology and myocardial perfusion by single reproducible non-invasive contrast enhanced CT acquisition by using DECT scanners with high sensitivity and specificity as well as high diagnostic accuracy without the need to increase the contrast material or radiation dose

Patients and methods: this study was done during the period from October 2016 to December ,2017; age was ranged between 42 to 73 years old, were 35 patients with CAD diagnosed by cCTA underwent DECT for assessment of myocardial perfusion. The study included 35 patients referred for DECT myocardial perfusion examination in the Police Authority Hospitals, Radiodiagnosis Department in Cairo after diagnosing by cCTA. Each patient included in the study was subjected to full history taking, reviewing medical sheet, cCTA and CT myocardial perfusion examination. Technique was performed by using Aquilion one dynamic volume 320 detector rows CT, Toshiba Medical System, Tochigi-ken, Japan

Results: our study showed a significant correlation and good agreement between the findings of DECT myocardial perfusion defects and the findings of stenosis and its degree on cCTA on a segmental basis with 83% sensitivity, 87% specificity, 86% accuracy, 74% positive predictive value and 92% negative predictive value

Conclusion: DECT myocardial perfusion has high diagnostic as compared to cCTA as the gold reference standard

Role of ADC map MR imaging in prediction of local aggressiveness of prostate cancer

Objective: of this study is to evaluate the relationship between ADC map values of MR imaging and local aggressiveness of the prostate Cancer via comparing the ADC values and Gleason score in prostate Cancer

Methodology: this study carried out in Radiology Department of Ain Shams University Hospitals. 21 patients with pathologically proven prostate cancer underwent pelvic MRI examination including diffusion weighted imaging [DWI] and apparent diffusion coefficient [ADC]

Result: The mean ADC value is inversely related to Gleason Score

Accuracy of lung ultrasonography in diagnosis of community acquired pneumonia as compared to chest x-ray in pediatric age group

Objective: It was aimed at investigating the role of lung ultrasonography in assessment of pneumonia as compared to chest x-ray in pediateric age group

Purpose: to evaluate the ultrasound efficiency in the assessment of pneumonia in pediatric age group as compared to chest x-ray

Methodology: This study was carried out at the general pediatric wards and PICUs of El-Demrdash hospital, Ain Shams University.40 patients were clinically diagnosed with pneumonia. For every child included in the study, a chest x-ray and a chest US were performed

Result: the detection rate of consolidative patches was higher in ultrasound compared to the x-ray technique

Conclusion: Lung ultrasound is safe and accurate for the diagnosis suspected cases of community acquired pneumonia and it is more sensitive than chest X-ray and allows a radiation free technique for detection of consolidations in children, thus reducing radiation exposure in this population
