This study examines the effect of prostatic arterial embolisation (PAE) on various prostate gland anatomical zones. The authors concluded that PAE can significantly decrease prostate volumes, and poor clinical outcomes are associated with smaller volume reductions.

Key Points:

• The MRI segmentation method provides detailed comparisons of prostate volume change.

• Prostatic arterial embolisation (PAE) decreased central gland and peripheral zone volumes.

• Prostates with infarction after PAE showed larger decreases in volume.

• A larger decrease in prostate volume is associated with clinical success.
