abstractbackground: although electronic portal imaging devices (epids) have originally developed for positioning verification, they can also be used for dosimetric purposes. in the current work, the dose response of minimum detectable thickness of a scanning liquid filled ion chamber epid, slic-epid, and the variation of transmitted dose with the shift of inhomogeneity inside of phantom was als...

The Echinococcus granulosus tapeworm causes hepatic echinococcosis. It is endemic in the Mediterranean region, Middle East, and South America. Human infection is secondary to accidental consumption of ova in feces. Absorption through the bowel wall and entrance into the portal circulation leads to liver infection. This case involves a 34 y/o Moroccan male with an echinococcal liver cyst. His ch...

we report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. he presented with bleeding esophageal varices and was initially treated by sclerotherapy. at laparotomy, portal pressure was 40 cmh20 but fell to 20 cm h20 after the fistula was treated with splenectomy. all symptoms disappeared shortly after operation and t...

objective(s): in this study, we aimed to describe the characteristics of portal vein tumor thrombosis (pvtt), complicating hepatocellular carcinoma (hcc) in contrast-enhanced fdg pet/ct scan. methods: in this retrospective study, 9 hcc patients with fdg-avid pvtt were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (fdg pet/ct), which is a comb...

To study effect air flow electric (ERS) locomotive crew using SolidWorks program, Flow Simulation module. Methods: Investigation principle formation en...

Computer-aided analysis of venous vasculatures including hepatic veins and portal veins is important in liver surgery planning. The analysis normally consists of two important pre-processing tasks: segmenting both vasculatures and separating them from each other by assigning different labels. During the acquisition of multi-phase CT images, both of the venous vessels are enhanced by injected co...

case presentation we report a case of idiopathic colonic varices, diagnosed at a routine colonoscopy performed for nespecific abdominal disturbances in a female patient without liver disease or pancreatic conditions responsible for portal hypertension development. conclusions the development of colonic varices in the absence of a certain trigger represents a major issue for practitioners due to...
