Multi detector computed tomography (MDCT)

Diagnostic reference levels (DRLs) have been developed for adult and paediatric multi detector computed tomography (MDCT) procedures. Medical imaging providers are required under the ARPANSA Code of Practice (RPS C-5 Section 3.2.15, previously RPS 14 Section 3.1.8) to regularly compare typical patient doses to the national DRLs to optimise the doses delivered to patients.

MDCT survey

Login to, register for, or get more information about the MDCT survey. The survey is a tool for MDCT providers to compare the doses they deliver with the national DRLs and thereby meet their regulatory obligations – all while helping shape the future DRLs.

MDCT statistics

See how the Australian DRLs were derived and how MDCT doses have changed since the MDCT survey started.
