CCTA radiation dose
A fresh look by Aunt Minnie on how to reduce the radiation dose in Coronary CT angiography performed on MSCT scanners. Good control of heart rate and use of ALARA (as low as reasonably achievable) radiation parameters is the key.

Radiation reference levels
A new article on dose reduction for routine CT scanning is a multicenter study that proposes reference levels of radiation dose and methods of dose reduction, albeit maintaining diagnostic confidence. See it before print in Radiology at http://radiology.rsnajnls.org/cgi/content/abstract/2403050993v1?papetoc
