Background: Diabetic nephropathy is one of the cause of the end stage of renal disease (ESRD). Hyperglicemia activate intrarenal Renin-Angiotensin system and highly AngiotensinII is produced locally in glomeruli. In this research AT1(Angiotensin type 1) receptors blocked by Losartan and effects of this drug in inhibition of renal structural lesions were assessed quantitatively. Materials & me...

OBJECTIVES This study sought to determine the accuracy of 3-dimensional, quantitative measurements of coronary plaque by computed tomography angiography (CTA) against intravascular ultrasound with radiofrequency backscatter analysis (IVUS/VH). BACKGROUND Quantitative, 3-dimensional coronary CTA plaque measurements have not been validated against IVUS/VH. METHODS Sixty patients in a prospect...

PURPOSE To examine a new way of body diffusion weighted imaging (DWI) using the short TI inversion recovery-echo planar imaging (STIR-EPI) sequence and free breathing scanning (diffusion weighted whole body imaging with background body signal suppression; DWIBS) to obtain three-dimensional displays. MATERIALS AND METHODS 1) Apparent contrast-to-noise ratios (AppCNR) between lymph nodes and su...

In functional magnetic resonance imaging (fMRI) head motion can corrupt the signal changes induced by brain activation. This paper describes a novel technique called Prospective Acquisition CorrEction (PACE) for reducing motion-induced effects on magnetization history. Full three-dimensional rigid body estimation of head movement is obtained by image-based motion detection to a high level of ac...

Hepatectomies are resections in which segments of the liver are extracted. While medical images are fundamental in the surgery planning procedure, the process of analysis of such images slice-by-slice is still tedious and inefficient. In this work we propose a strategy to efficiently and semi-automatically segment and classify patient-specific liver models in 3D through a mobile display device....

Direct volume rendering (DVR) is a very useful visualisation technique. However, the difficulty in specifying a suitable transfer function often discourages its application to visualisation problems. This work presents a technique for providing meaningful and fast visual feedback that greatly facilitates the transfer function specification process. The feedback is based on a slice-based preview...

Abstract Laparoscopic sleeve gastrectomy (LSG) is considerably utilized as a bariatric method for treating morbid obesity through the reduction of stomach volume. The present study attempted to assess volumetric changes gastric reservoir 1 year after LSG using multi-slice spiral computed tomography (MSCT) well verify their association with weight loss. current prospective 40 consecutive obese p...
