DECT iodine maps show superior performance for the detection of fixed and mixed perfusion deficits compared with SCT spectra. Read more

We sought to describe the performance of DE-CTA of the supraaortic vessels with a novel dual source CT system with special emphasis on image quality and post-processing related artifacts. Read more

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
