The utilization of dual source computed tomography (DSCT) might improve the visualization of the coronary arteries by imaging at a temporal resolution of 83 milliseconds, independent of heart rate. Read more

Recent developments in CT technology primarily by reducing the cardiac motion and the radiation dose usage in congenital heart disease evaluation have helped expand the indications for CT usage. Read more

The advantge of DSCT in cardiac imaging is the good temporal resolution. The temporal resolution of the Definition is 83 ms and in the Flash it is even 75 ms, providing good image quality at high heart rates (see paper). Read more

This first article of our new Dual Energy series introduces you to Dual Energy. Dual Source CT had initially been developed to increase the temporal resolution of CT for cardiac imaging. By now, Dual Energy CT is ready for routine clinical use. Read more

Functional analysis using MDCT has been limited by insufficient temporal resolution. The aim of this study was to assess the performance of a dual-source CT system with improved temporal resolution in the determination of both volume- or time-dependent functional parameters and regional wall motion in comparison with cine MRI.

Purpose To determine regional and global left ventricular (LV) functional parameters and to perform segmental wall thickness (SWT) and motion (WM) analysis of dual-source CT (DSCT) with optimized temporal resolution versus MRI. Materials and methods 30 patients with known or suspected CAD, non-obstructive HCM, DCM, ARVCM, Fallot Tetralogy, cardiac sarcoidosis and … Read more
