pECG(dual-step)128-slice DSCT is feasible for the evaluation of coronary arteries and cardiac function without heart rate control in patients in stable sinus rhythm at a low radiation dose. Read more

The aim of the study was to evaluate radiation exposure of a chest pain protocol with ECG-gated dual-source computed tomography (DSCT). Read more

The objective was to prospectively investigate the diagnostic accuracy of high-pitch (HP) dual-source computed tomography coronary angiography (CTCA) compared with catheter coronary angiography (CCA) for the diagnosis of significant coronary stenoses. Read more

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 following question has been sent by Daniel Newman: I am asked frequently about the difference between dual energy and dual source.  It seems that for most people the terms are interchangeble.  However, not all CT systems utilize 2 tubes.  Can you explain to me the pros and cons of each … Read more

According to the information of Investigative Radiology, there is a special issue on ‘Advances in CT technology’ scheduled for publication during the summer of 2010. The focus of this special issue will be on recent technical developments of CT, including specifically dual source/ dual energy CT and multidetector CT with 128 … Read more

Background Dual-source computed tomography (DSCT) was introduced with significant hardware and software changes compared with single-source CT (SSCT), resulting in improved temporal resolution (83 ms) and the potential for improved image quality. The effect of these changes on radiation dose requirements for coronary CT angiography in clinical practice has not been … Read more
