TLDR
The increase in spatial and temporal resolution with 64-slice CTA is associated with an increased radiation dose for coronary CTA and dose-saving algorithms are very effective in reducing radiation exposure.Abstract:
Background— Multislice computed tomography angiography (CTA) is a promising technology for imaging patients with suspected coronary artery disease Compared with 16-slice CTA, the improved spatial read more

Estimating Risk of Cancer Associated With Radiation Exposure From 64-Slice Computed Tomography Coronary Angiography
TL;DR: Estimates derived from simulation models suggest that use of 64-slice CTCA is associated with a nonnegligible LAR of cancer, which varies markedly and is considerably greater for women, younger patients, and for combined cardiac and aortic scans.

TL;DR: In this article, a cross-sectional, international, multicenter, observational study was conducted to estimate the radiation dose of CCTA in routine clinical practice as well as the association of currently available strategies with dose reduction.

Estimated Radiation Dose Associated With Cardiac CT Angiography. Commentary
Jörg Hausleiter,Tanja Meyer,Franziska Hermann,Martin Hadamitzky,Markus Krebs,Thomas C. Gerber,Cynthia H. McCollough,Stefan Martinoff,Adnan Kastrati,Albert Schömig,Stephan Achenbach,Andrew J. Einstein +11 more
TL;DR: The comparable diagnostic image quality of CCTA may support an increased use of dose-saving strategies in adequately selected patients and effective strategies to reduce radiation dose are available but some strategies are not frequently used.

Radiation Dose to Patients From Cardiac Diagnostic Imaging
Andrew J. Einstein,Kevin W. Moser,Randall C. Thompson,Manuel D. Cerqueira,Milena J. Henzlova +4 more
TL;DR: Physicians ordering and performing cardiac imaging should be very familiar with the dosage of radiation from cardiac diagnostic tests and ways in which dose can be minimized, including nuclear scintigraphy, CT for calcium scoring and coronary angiography (CTCA), and conventional coronary angIography (CCA).

Strategies for reducing radiation dose in CT.
Cynthia H. McCollough,Andrew N. Primak,Natalie N. Braun,James M. Kofler,Lifeng Yu,Jodie A. Christner +5 more
TL;DR: The dose reduction strategies described in this article must be well understood and properly used to satisfy the ALARA principle and the use of CT must also be justified for the specific diagnostic task.
