CT angiography with volume rendering: advantages and applications in splanchnic vascular imaging.
The authors compared volume rendering with maximum intensity projection (MIP) and shaded surface display as a technique for generating three-dimensional (3D) images of the vasculature from spiral computed tomography (CT) data sets. In four patients with pathologic splanchnic vasculature, the advantages of volume-rendered display are illustrated for depiction of 3D vascular anatomy, vascular and...
متن کاملEfficient CPU - based Direct Volume Rendering For CT - Angiography
This work reports the development of a CPU-based Direct Volume Rendering (DVR) software, which was implemented for medical visualisation in the field of CT-Angiography. An interactive DVR-plugin was finally added to the so called AngioVis-Toolbox, a software for post-processing and visualisation of CTA datasets. This work was focusing on finding adequate solutions to provide an interactive beha...
متن کاملCardiac neoplasms and pseudotumors: imaging findings on multidetector CT angiography.
A wide spectrum of masses can affect the heart, ranging from non-malignant entities, such as thrombi, to aggressive primary cardiac tumors, such as angiosarcomas. Echocardiography and magnetic resonance imaging have traditionally formed the mainstay techniques for assessing these lesions. Recent technological advances have seen ECG-gated multi-detector computed tomography (M...
متن کاملCT angiography with volume rendering for quantifying vascular stenoses: in vitro validation of accuracy.
OBJECTIVE The purpose of this study was to evaluate the accuracy of CT angiography with volume rendering for quantifying vascular stenoses in vitro. MATERIALS AND METHODS Vascular models with three degrees of stenosis (33%, 67%, and 83%) were imaged at three orientations to the axial plane (parallel, perpendicular, or 45 degrees ) using helical CT with 2-mm collimation and two pitches (1 or 2...
متن کاملArteriogenesis: noninvasive quantification with multi-detector row CT angiography and three-dimensional volume rendering in rodents.
PURPOSE To evaluate two-dimensional (2D) multi-detector row computed tomographic (CT) angiography and three-dimensional (3D) volume rendering for depiction of patterns of arterial growth and quantification of blood vessel density and volume. MATERIALS AND METHODS The institutional animal care and use committee approved this study. The right femoral artery and its branches were ligated and exc...
