  • Fig. 3 MIP reconstruction showing the presence of the coronaries

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

posted by Michael M. Lell, M.D. | Jan 3, 2012
Michael M. Lell, M.D.

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
