Introduction: Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract associated withhigh rates malignant transformation. Most GISTs present asymptomatically. They best identified by computedtomography (CT) scan and most stain positive for CD 117 (C-Kit), CD34, and/ or DOG-1. There have been many riskstratification classifications systems which calculated based ...

conclusions our case is the first report of ivus imaging of subclavian stenosis resulting from takayasu’s arteritis and provides insight into the pathology behind such lesions. introduction takayasu’s arteritis (ta) is a chronic, idiopathic, inflammatory disease that affects large elastic arteries, including the aorta and its main branches. no consensus exists currently on the superiority of su...

conclusion adc, fa, and t2* values may quantitatively reflect the microstructural characteristics of np, therefore they could be used to detect the minimal changes of early ldd. results the adc, fa, and t2* values were different (p < 0.05) among different rois within the same disc or among corresponding rois in different level discs. while the average values of adc increased regularly with the ...

background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...

abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

Computed tomography technology is one of the important technology techniques, which shows the inside part of the human body through scanning the specific area. FDT Technique aims to augment the precision of the CT image thresholding by implementing an advanced thresholding approach from four different directions. Based on the FDT technique, the foreground and back ground pixel values of the adj...
