The licensee prepared and delivered a therapeutic dose of TheraSpheres to a patient's liver on August 14, 2014. The written directive was for 120 Gy to the liver with 27 mCi of Y-90 TheraSpheres.

Although the licensee prepared the vial in accordance with the manufacturer's instructions, 20% of the TheraSpheres remained in the bottom of the vial and did not go into suspension.
The patient and referring physician have been notified.
The Bureau [Ohio Bureau of Radiation Protection] will be conducting a follow-up investigation regarding this event.
