DSCT imaging of myocardial infarction
|
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

Dual-source CT: effect of heart rate, heart rate variability, and calcification on image quality and diagnostic accuracy.
|
To prospectively evaluate the effect of heart rate, heart rate variability, and calcification on dual-source computed tomography (CT) image quality and to prospectively assess diagnostic accuracy of dual-source CT for coronary artery stenosis, by using invasive coronary angiography as the reference standard.

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

Prospectively ECG-triggered high-pitch spiral acquisition for coronary CT angiography using dual source CT: technique and initial experience
|
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

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