Prostate MRI Transitional Zone Volume Predicts BPH Enucleation Volume Better than Alternative Modalities.

Guidelines for benign prostate hyperplasia (BPH) interventions are volume based. The degree to which different imaging modalities actually correlate to treated volume is not known for BPH. The present study compares the accuracy of preoperative ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and MRI-transitional zone (TZ) to BPH enucleation weight.
