MedSun: Newsletter #42, November 2009

FDA MedWatch Safety Alert

FDA has become aware of radiation overexposures during perfusion CT imaging to aid in the diagnosis and treatment of stroke. Over an 18-month period, 206 patients at a particular facility received radiation doses that were approximately eight times the expected level. In some cases, this excessive dose resulted in hair loss and erythema. FDA encourages every facility performing CT imaging to review its CT protocols and be aware of the dose indices normally displayed on the control panel.
