Dr. James P. Earls, Director of Cardiovascular CT and Body and Cardiovascular MRI at FRC reviewed CT scans from over 4,000 consecutive CT examinations in 2009. Approximately 20% of these patients had a prior CT scan performed on an older generation scanner. The results of this study were presented at the Annual Meeting of the Radiological Society of North America in November 2009.

Following is a before and after comparison of average dose for typical CT scans:

* measurements are in millisieverts (mSv)

** results may vary due to patient size and scanning protocol

the latest low-dose scanning technology benefits all patients, but is particularly advantageous to children who are highly sensetive to radiation, as well as pateints who require CT scans to monitor a disease or condition.

FRC will provide any needed consultation regarding CT scanning and radiation dose. For more information, call 1-888-4-LOW-DOSE (1-888-456-9367) to speak directly to a knowledgeable, professional technologist who can answer questions and address any concerns relative to CT scanning.

By contacting us at this number before arriving for a scheduled CT exam, we can estimate anticipated radiation exposure prior to the procedure. You can also call after a CT has been performed to learn the actual dosage received from the exam
