Answer to Question #11493 Submitted to "Ask the Experts"
The following question was answered by an expert in the appropriate field:
I had two computed tomography (CT) scans performed, one of the chest and one of the brain. Is the radiology department required to show effective radiation dose in millisieverts if asked by the patient? This center was accredited by the American College of Radiology. They told me that the dose was based on patient weight.
Regulations vary by state, so I cannot answer whether a radiology department is required to provide effective dose upon request. Dose is indeed based on patient size, but it is also based on machine parameters. The diagnostic medical physicist or medical health physicist at the radiology department should be able to provide an estimate of your effective dose from these CT scans.
