CT imaging diagnostic reference levels
12 February 2020

The radiation dose from a CT scan, while low, is nonetheless assumed to contribute a small additional risk to a patient’s lifetime risk of cancer. ARPANSA's new reference levels show patients in Australia are receiving much lower doses than 5-10 years ago.

The MDCT survey collects de-identified data on patient dose for six adult (15+ years) anatomical protocols and three child (5-14 years) and infant (0-4 years) anatomical protocols. The data is used to establish and update National Diagnostic Reference Levels for common CT imaging procedures. The six adult protocols are: Head, Neck, Chest, Abdomen-Pelvis, Chest-Abdomen-Pelvis, and Lumbar Spine. The three child and infant protocols are: Head, Chest, and Abdomen-Pelvis.
