PURPOSE To assess unenhanced and delayed phase computed tomographic (CT) images combined with arterial phase images for detecting endoleaks after endovascular treatment for abdominal aortic aneurysm (AAA). MATERIALS AND METHODS CT scans were retrospectively evaluated for the presence of endoleaks after endovascular treatment of AAAs in 33 patients with(More)
PURPOSE To retrospectively assess endoleak shapes and locations within aneurysms to differentiate type II from type I and type III endoleaks. MATERIALS AND METHODS The institutional review board granted an exemption for this HIPAA-compliant study; patient informed consent was not required. A retrospective review of arterial phase helical computed(More)
The aim of our study was to compare the accuracy of non-contrast spiral CT with ultrasound (US) for the diagnosis of ureteral calculi in the evaluation of patients with acute flank pain. 62 consecutive patients with flank pain were examined with both CT and US over a period of 9 months. All patients were prospectively defined as either positive or negative(More)
Multiple nontraumatic splenic emergencies are encountered during the imaging of patients in emergency room. Occasionally, patients are investigated for symptoms of suspected splenic pathology, such as abscess, infarct, symptomatic splenic artery aneurysm and pseudoaneurysm, splenic torsion, or rupture. More often, however, splenic emergencies, such as(More)
The purpose of this study was to catalogue spleen and liver features by US in a cohort of 103 pediatric patients with Gaucher disease, and to document response to enzyme replacement therapy by serial US examination. There were 42 boys and 61 girls, 2 were splenectomized. Forty-eight patients received enzyme replacement therapy (ERT). At presentation all(More)
Gaucher disease, the most prevalent lysosomal storage disorder, is characterized by hepatosplenomegaly, hypersplenism, and rarely, neurological involvement. The most variable symptoms relate to skeletal disease, and both onset and progression are difficult to predict on the basis of genotype. This review describes findings from a large referral clinic (>(More)
As a result of the rising epidemic of obesity, understanding body fat distribution and its clinical implications is critical to timely treatment. Visceral adipose tissue is a hormonally active component of total body fat, which possesses unique biochemical characteristics that influence several normal and pathological processes in the human body. Abnormally(More)
With the advent of enzyme replacement therapy for Gaucher disease, there was a need to assess response to treatment repeatedly over relatively short periods of time; hence abdominal ultrasound was used in our referral clinic because it was convenient, safe and inexpensive. In 100 treated patients monitored for 2-7 years, nearly all had reduction in(More)
Multiple nontraumatic peritoneal and mesenteric emergencies are encountered at imaging of patients in the emergency department. Peritoneal and mesenteric emergencies are usually detected in patients in the emergency department during evaluation of nonspecific abdominal pain. A high index of suspicion is required for the establishment of early diagnosis and(More)
