Four-Dimensional Cardiac Image by Helical Computed Tomography

Four-dimensional cardiac image by helical computed tomography.

Ultrasound and MRI are useful in assessing wall motion and systolic thickening with 2D images. Volumetric data of the helical CT provide frozen 3D images. We sought to determine whether helical CT could assess left ventricular wall motion with 3D animation. We have developed a new cardiac application, ventriculography by 4D enhanced helical CT (4D-CT-VG), which can assess wall motion with 3D an...

Left ventricular hypertrophy demonstrated by four-dimensional myocardiography by helical computed tomography.

We present 4D images of hypertrophied myocardium in patients with essential hypertension, hypertrophic cardiomyopathy with asymmetrical septal hypertrophy, and apical hypertrophic cardiomyopathy using helical computed tomography (CT) ( Figures 1 through 4). Previously, we reported on 4D CT-ventriculography, which can assess right and left ventricular morphology and motion.1 In 4D ventriculograp...

Quantitative assessment of four‐dimensional computed tomography image acquisition quality

The purpose of the present work was to describe the development and validation of a series of tests to assess the quality of four-dimensional (4D) computed-tomography (CT) imaging as it is applied to radiation treatment planning. Using a commercial respiratory motion phantom and a programmable moving platform with a CT phantom, we acquired 4D CT datasets on two commercial multislice helical CT ...
