The following information was provided by the
Florida Bureau of Radiation Control (
BRC) via email:
BRC was notified on 7/28/25 that on Friday, 7/25/25, a patient at Advent Health, Daytona was receiving Y-90 TheraSphere treatment for the liver. The patient received a dose which differed by more than 20 percent from the prescribed dose. Treatment was provided in 2 segments, denoted in 2 scripts. One segment received the full prescribed treatment, while the other segment received 51 percent of the intended treatment. Due to the treatment being provided as 2 scripts, treatment two differed by more than 20 percent.
The [licensee's] radiation safety officer states that the dosimeter on the vial showed a dose of 0, but when all administration materials were removed, the residual within the equipment was much higher than expected. The primary care provider has been informed. It is unknown if the patient has been informed.
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
