ABSTRACT
Objective To explore the utility of cone-beam CT in the evaluation of prostatic arterial embolization (PAE). Methods In a retrospective study, images of DSA and cone-beam CT for PAE in 81 patients with moderate to severe grade benign prostatic hyperplasia were evaluated. In 162 cases of internal iliac arteries (ⅡAs) in 81 patients, images of 6 ⅡAs were excluded due to the technical problems. Therefore, images of 156ⅡAs were included for evaluation. We aim to evaluate the utility of cone-beam CT versus DSA in differentiating PAs and their origins, and demonstrating anastomoses with adjacent arteries. Statistical analyses were performed with Chi-square test to compare the rate of demonstrating vessels between cone-beam CT and DSA. Results One hundred and sixty-one PAs were demonstrated in 156ⅡAs by selective DSA and Cone-beam CT. Cone-beam CT and DSA images demonstrated 158 (98.1%, 158/161) and 130 (80.8%, 130/161) PAs, respectively. The statistical difference was significant (χ2=25.78, P cone-beam CT and DSA images. The percentage of PA anastomoses demonstrated by cone-beam CT was 42.3%(66/156), which was higher than DSA (31.4%, 49/156). The statistical difference was significant (χ2=3.98, P<0.05). Conclusions Cone-beam CT is useful in demonstrating PAs and their origins fromⅡAs, as well as anastomoses with adjacent arteries.
