Noninvasive Coronary Angiography Using Dual-Source Computed Tomography in Patients With Atrial Fibrillation
 |
The purpose of this study was to assess the image quality of coronary CT angiograms with coronary angiography, using a dual-source CT scanner (DSCT), comparing systolic and diastolic reconstruction techniques. Additionally, we sought to evaluate the diagnostic accuracy of DSCT with coronary angiography as the standard of reference. Read more

Effect of dual-source cardiac computed tomography on patient radiation dose in a clinical setting: comparison to single-source imaging
 |
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

Coronary CT angiography: automatic cardiac-phase selection for image reconstruction
 |
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
