USFDA Safety Investigation of CT Brain Perfusion Scans

The Food and Drug Administration (FDA) recently issued an initial notification of a safety investigation regarding CT brain perfusion scans. FDA has become aware of radiation overexposure during perfusion CT imaging which aids in the diagnosis and treatment of a stroke. This incident included 206 patients at one particular facility involving this one kind of study. While neither the facility nor the state is named in the report, we are concerned this may reflect more widespread problems with CT quality assurance programs.

We are bringing this notice to your attention so that you can help ensure that this important information is received by the appropriate members of your radiology staff to ensure the safety and efficacy of CT imaging at your facility.
