| event text = An Authorized User physician from the University of Michigan Department of Radiation Oncology planned two liver infusion treatments for a patient with unresectable hepatocellular carcinoma using Y-90 Theraspheres. As part of treatment preparation, an MRI was performed on the patient to determine the patient's liver segment volumes. Liver segment volumes are used in calculating the Y-90 activity needed to deliver the prescribed radiation dose to particular segments of the liver. The first treatment was to the right lobe and medial segment of the patient's liver and was performed on 12/15/2010. It proceeded without incident and in accordance with the written directive. | | event text = An Authorized User physician from the University of Michigan Department of Radiation Oncology planned two liver infusion treatments for a patient with unresectable hepatocellular carcinoma using Y-90 Theraspheres.

The Authorized User physician scheduled a second separate treatment to the patient's left lobe to be performed on 3/9/2011. The Authorized User ordered a 74.4 Gy dose to the left lobe of the liver. The medical physicist calculated a corresponding dosage of 60.5 mCi of Y-90 to be infused into the left lobe of the liver. | The Authorized User physician scheduled a second separate treatment to the patient's left lobe to be performed on 3/9/2011.
