New Image Wisely Radiation Safety Case Covers Balancing Image Quality and Radiation Dose in Cardiac CT Angiography

Balancing Image Quality and Radiation Dose in Cardiac CT Angiography, a newImage Wisely® radiation safety case— is now available to help radiologists, imaging technologists and medical physicists to assess their understanding of important radiation safety concepts, including dose monitoring and optimization. This is the newest in a series of free, online and mobile-compatible Image Wisely educational offerings, developed with the assistance of theAmerican College of Radiology (ACR).
This case explains how cardiac CT angiography scan parameters affect radiation dose exposure and image quality.“Cardiac CT angiography (CTA) is a valuable imaging tool currently utilized in a wide variety of inpatient, outpatient and emergency settings,” said Nandini (Nina) Meyersohn, MD, of Massachusetts General Hospital/Harvard Medical School in Boston, who was lead author of the case along with co-authors Brian B. Ghoshhajra, MD, MBA. and Udo Hoffmann, MD, MPH, also of Massachusetts General Hospital/Harvard Medical School.“When using CT, we know that we must make tradeoffs in image quality to reduce radiation dose; however, diagnostic quality images are always theprimary goal. Knowledge of the scan parameters that affect both radiation dose and image quality, techniques to modify scan acquisition, and image post-processing to improve this balance is essential for physician imagers and technologists.”
Several radiation safety cases are presented throughout the y...
