Case: Coronary and aortic CTA at a 7-week old boy: DLP5
 |
The scan was performed with bolustracking technique. The reason was that the i.v. cannula was placed on the forehead, allowing the use of a manual delay is not recommended. Read more

Radiation exposure and image quality in staged low-dose protocols for coronary dual-source CT angiography: a randomized comparison
 |
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
