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

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

The aim of the study was to estimate radiation exposure of coronary calcium scoring and angiography using ECG-gated and ECG-triggered DSCT. Read more

This publication evaluates the diagnostic accuracy of dual-energy CT (DECT) in renal mass characterization using a single-phase acquisition. Read more

New generation DSCT scanners offer different x-ray spectra for Dual Energy imaging. Yet, an objective, manufacturer independent verification of the dose required for the different spectral combinations is lacking. Read more

The following question has been sent by Patrick, CT Tech: Our facilty is currently operating a siemens Definition Scanner. I was hoping you could recommend some reading material on Dual Source CT. Also some info on how to reduce radiation exposure. Ralf Bauer, MD, Clinic of the Goethe University, Frankfurt, Germany: Dear … Read more
