Purpose: The purpose of this study is to evaluate Ga-68 MAA distribution on PET/MRI after
injection into the prostatic arteries in patients without prostate cancer who are being
treated with prostate artery embolization for benign prostatic hyperplasia.
Participants: Study subjects will be 5 men scheduled to undergo the PAE procedure at UNC
Hospital for benign prostatic hyperplasia.
Procedures (methods): Study subjects will undergo PAE using the standard technique. Prior to
embolization of the prostatic artery with the bland embolic agent, Ga-68 MAA will be
injected. Standard departmental radiation protection procedures will be followed. After the
PAE procedure is complete, the patient will be transported to the UNC Biomedical Research
Imaging Center to undergo PET/MRI.
