Automatic three-dimensional detection of prostatic arteries using cone-beam CT during prostatic arterial embolization

J Vasc Interv Radiol. 2015 Mar;26(3):413-7. doi: 10.1016/j.jvir.2014.11.009.

Abstract

The purpose of this study was to evaluate the automatic three-dimensional detection of prostatic arteries (PAs) with the use of dual-phase cone-beam computed tomography (CT) imaging and vessel-tracking software during prostatic artery (PA) embolization (PAE). In six patients, six right PAs and five left PAs were detected by using the software (sensitivity, 92%). The false-positive arteries (right side, 14%; left side, 25%) were deleted after cone-beam CT review. Automatic software detection of PAs from cone-beam CT may permit identification of the PA during PAE.
