High-speed CTA is a promising technique for significantly reducing CTA-related radiation dose in non-obese patients. Read more

To evaluate staged low-dose approaches for coronary CT angiography (CTA) in which a standard sequence was added if the low-dose sequence did not allow reliable rule-out of coronary stenosis. Read more

We evaluated the feasibility and image quality of a new scan mode for coronary computed tomography angiography (CTA) with an effective dose of less than 1 mSv. Read more

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

To compare in vivo DNA lesions induced during helical and sequential coronary CTA and to evaluate the effect of CT parameters on double-strand break (DSB) levels. Read more

To evaluate the feasibility and performance of dual energy CT during arterial phase in coronary CT angiography for the detection of chronic infarction compared with late enhancement MRI (LE-MRI) and histopathology in a porcine model of reperfused myocardial infarction. Read more

We evaluated a new, subsecond high-pitch scan mode (HPM), which obviates the need of sedation and to hold the breath. Read more
