A 67-year old female with symptoms related to angina and an Agatston score of 632, a BMI of 24.3 kg/m2, and a heart rate during scanning of 67 beats per minute. (a) An example of a volume rendered multiplanar reconstruction of the right coronary artery (RCA) from a coronary computed tomography angiography performed at 192-slice dual-source computed tomography using a tube voltage of only 70 kV. (b) The same RCA in curved multiplanar reconstruction. Both demonstrate superior diagnostic image quality despite the low kV settings.
