The utilization of dual source computed tomography (DSCT) might improve the visualization of the coronary arteries by imaging at a temporal resolution of 83 milliseconds, independent of heart rate. Read more

Iterative image reconstruction techniques incrementally improve the assessment of coronary artery stents by reducing image noise and beam-hardening artifacts. Read more

To evaluate the quality of stent lumen delineation using DSCT in the standard-pitch mode (SP) as compared to the high-pitch mode (HP) in a phantom study. Read more

The HPS mode of 128-slice dual-source CT yields fewer artefacts inside the stent lumen compared with SPIR and SEQ, but image noise is higher. Read more

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

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.
