The following was received from the
Utah Department of Environmental Quality (the Division) via email:
At approximately 1030 MDT, the [Radiation Safety Officer] for the licensee notified the Division that a patient had been administered an isotope to perform a PET scan. The technician double checked with the ordering physician and found that the order was supposed to have been for a CT scan, not a PET scan. The order received showed it was a PET scan. An investigation is being conducted to see how the order was changed.
The patient was administered about 10.6 mCi of FDG when a CT scan was to be performed. Therefore, the dose was greater than 20 percent of the prescribed dose. The order received by the radiology department showed that a PET scan had been ordered. The TEDE to the patient was less than 5 rem and the highest organ dose (to the bladder wall), was less than 50 rem. The patient was administered the FDG at about 1300 EDT on May 4, 2022. The FDG was allowed to decay and the patient was later given a CT exam.
At this time, this is all the information that the Division has, an investigation will be conducted, and an update will be provided at a later date.
