Abstract
Purpose: To prospectively analyze the radiation exposure of patients and interventional radiologists during prostatic artery embolization (PAE).
Materials and Methods: Twenty-five consecutive PAE procedures performed with an Artis zee system in a single center by an interventional radiologist were prospectively monitored. The mean age, weight, and prostate volume of the patients were 65.7 year (range, 43-85 y), 71.4 kg (range, 54-88 kg), and 79 cm(3) (range, 36-157 cm3), respectively. In addition to Digital Imaging and Communications in Medicine radiation data, direct measures were also obtained. Radiochromic film was used to evaluate peak skin dose (PSD). The radiologist wore a protective apron and a thyroid collar, and a ceiling-suspended screen and a table curtain were used. To estimate the absorbed doses, nine pairs of dosimeters were attached to the operator's body.
Results: The average fluoroscopy time was 30.9 minutes (range, 15.5-48.3 min). The mean total dose area product (DAP) was 450.7 Gy . cm(2) (range, 248.3-791.73 Gy . cm(2)) per procedure. Digital subtraction angiography was responsible for 71.5% of the total DAP, followed by fluoroscopy and cone-beam computed tomography. The mean PSD was 2,420.3 mGy (range, 1,3903,616 mGy). The average effective dose for the interventional radiologist was 17 mu Sv (range, 4-47 mu Sv); values for the eyes, hands, and feet were obtained, and were all greater on the left side.
Conclusions: PAE may lead to high x-ray exposures to patients and interventional radiologists.
