DSCT imaging of myocardial infarction

posted by Balazs Ruzsics, M.D., PhD | Dec 28, 2009
Balazs Ruzsics, M.D., PhD

Electro-cardiogram (ECG)-gated dual energy computed tomography (DECT) of the heart may enable spectral analysis of the myocardium for areas of decreased blood supply in addition to morphological assessment for coronary artery stenosis. We used DECT for evaluating a 49-year-old woman with known coronary artery disease and new onset chest pain. She … Read more

In this article we describe current multislice CT techniques for coronary artery imaging and illustrate coronary artery anomalies and clinically important coronary artery anatomy from the point of view of congenital heart disease. Read more

Dual-source CT with improved temporal resolution in assessment of left ventricular function: a pilot study.

posted by Anja Reimann, MD | Nov 3, 2009
Anja Reimann, MD

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.

Stephan Achenbach, M.D.

Objective We evaluated radiation exposure and image quality of a new coronary CT angiography protocol, high-pitch spiral acquisition, using dual source CT (DSCT). Materials and methods Coronary CTA was performed in 25 consecutive patients with a stable heart rate of 60 bpm or less after premedication, using 2 x 128 0.6-mm sections, 38.4-mm … Read more

The purpose of this article is to describe the current role of ECG-synchronized CT in the evaluation of patients with acute chest pain (triple rule-out) in the emergency department. Read more

DSCT: Effect on Regional and Global Left Ventricular Function Assessment Compared to Magnetic Resonance Imaging

posted by Kai U. Juergens, M.D. | Sep 29, 2009
Kai U. Juergens, M.D.

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
