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

To assess HU-based color mapping for characterization of coronary plaque, using intravascular ultrasound virtual histology (IVUS-VH) as a standard of reference. Dual-source computed tomography and IVUS-VH were prospectively performed in 13 patients. In five lesions, HU thresholds of the color-coding software were calibrated to IVUS-VH. In a 15-lesion verification cohort, … Read more

In conclusion, our initial experience suggests that DECT, as a single examination, might be promising for the integrative analysis of the coronary artery morphology and the myocardial blood supply and is in good agreement with ICA and SPECT. 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

Editorial Journal of Cardiovascular Computed Tomography (2008) 2 The number of diagnostic cardiac imaging tests involving x-rays has increased in the past decades. For example, the volume of diagnostic catheter angiography procedures performed in the United States increased from 2.45 million in 1993 to 3.85 million in 2002. (1) Similarly, the … Read more

Abstract We evaluated an algorithm for automatic selection of the cardiac phase with the least motion for image reconstruction at coronary computed tomography (CT) angiography (CCTA). We analyzed data of 100 patients (49 female, mean age 59 years) who had undergone retrospectively ECG-gated CCTA. Two experienced observers visually identified the … Read more

A41-year-old woman was admitted to the Medical University of South Carolina cardiology service with new-onset atrial fibrillation, with chest tightness, shortness of breath, and a nonproductive cough. As a child, she had a congenital bicuspid aortic valve with severe aortic stenosis that initially required commissurotomy, a bioprosthetic valve replacement at … Read more
