On the morning of 4/6, the Resident Physician reviewed the prescribing Physician's order for administration of a brain scan diagnostic test to image a tumor and instructed the technician to perform a "standard" brain scan which images blood flow. The Technician administered 30 mCi Tc-99m as instructed rather than the 3 mCi
Thallium prescribed. The
RSO noted that the test performed would result in a total dose of 3.22 mGy and a urinary bladder wall dose of 81 mGy (information from package insert). The
RSO does not believe there will be any adverse consequences to the patient in that this was a diagnostic test. The error was identified by the Director of Nuclear Medicine during review. The patient had not been informed as of the time of this report. The patient will be rescheduled for the appropriate diagnostic test after elimination and decay of the Tc-99m.
