Replacing vascular corrosion casting by in-vivo micro-CT imaging for building 3D cardiovascular models in mice [PDF]

, 2011
The purpose of this study was to investigate if in vivo micro-computed tomography (CT) is a reliable alternative to micro-CT scanning of a vascular corrosion cast. This would allow one to study the early development of cardiovascular diseases.

RefineCatDiff: Toward High‐Quality Medical Image Segmentation via a Categorical Diffusion Refinement Framework

Advanced Intelligent Systems, EarlyView.
This study proposes RefineCatDiff, a refinement framework for high‐quality medical image segmentation. By developing a categorical distribution‐based discrete diffusion process for refinement, the framework aligns well with the characteristics of image segmentation tasks. Experimental results on multiple datasets across different modalities demonstrate

Treatment of abdominal aorta aneurysms [PDF]

BMC Geriatrics, 2010
Background The best treatment of abdominal aorta aneurysms of the segments below the emergency of the renal arteries are still under discussion. In literature there are several studies that compare the retroperitoneal (R.P.) approach with the transperitoneal (T.P.) one or that suggest their possible variations. The R.P. approach offers the possibility

A Soft‐Tip Hydraulically Steerable Catheter for Enhanced Flexibility and Safety in Vascular Interventions

Advanced Intelligent Systems, EarlyView.
This study introduces a hydraulically steerable catheter with a soft tip in vascular procedures. The steering soft tip achieves a minimal diameter of 2.6 mm and supports a 180° bend. Real‐time shape and position tracking, facilitated by segmentation and endpoint detection techniques, improves navigation.

Ocular Findings as the Most Striking Manifestation of a SMAD3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Loeys‐Dietz syndrome (LDS) is a heritable connective tissue disorder with variable expressivity. It is a multisystemic condition mainly characterized by a propensity for arterial aneurysms and dissections, skeletal manifestations, hypertelorism, bifid uvula, craniosynostosis, and cutaneous features.
