The following is a summary of information provided by the licensee via phone:
A patient received a Y-90 Therasphere injection to the liver. The procedure was successfully completed with no abnormalities noted. After the procedure, an imaging study was conducted on the patient's liver, and it was determined that the Theraspheres had concentrated in a single segment of the liver (segment 4) when they had been expected to distribute throughout the entire liver. The calculated dose to the single segment would have exceeded the prescribed dose (633 Gy vice 91 Gy) due to the higher concentration of Y-90. The physician and patient were notified. No adverse effect is expected to the patient or the target organ.

After further review, the correct target was irradiated, the correct activity was injected and all procedures were followed. The average dose to the target matched the written directive. Thus, the event was not reportable, and the licensee is retracting the event.
