BACKGROUND Magnetic anchored surgical instruments (MASI), relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT) deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall characteristics in MASI applied environment to ...
BACKGROUND The composition of atherosclerotic plaque affects the likelihood of an atherothrombotic event, but prospective studies relating risk factors to carotid wall and plaque characteristics measured by MRI are lacking. We hypothesized that traditional risk factors are predictors of carotid wall and plaque characteristics measured 2 decades later. METHODS AND RESULTS A high-resolution con...
Computational Fluid Dynamics is intensively used to deepen the understanding of aneurysm growth and rupture in order to support physicians during therapy planning. However, numerous studies considering only the hemodynamics within the vessel lumen found no satisfactory criteria for rupture risk assessment. To improve available simulation models, the rigid vessel wall assumption has been discard...
PURPOSE To evaluate the effect of subclinical Helicobacter pylori infection on the gastric wall thickness with multislice computed tomography (MSCT). MATERIALS AND METHODS In 99 subjects without gastric disease, CT scans of the abdomen were obtained after water ingestion and intravenous contrast administration. CT images were evaluated for degree of luminal distention and the thickness of the...
OBJECTIVE To evaluate the normal antral wall thickness on MDCT and to determine the optimal cut-off value for differentiating normal and benign from malignant gastric wall thickening. MATERIAL AND METHOD MDCT scans of 154 patients, 22 malignancies, 66 benign conditions, and 66 normal findings, whose underwent both gastroscopy and MDCT within 30 days were retrospectively reviewed. The degree o...
