Association between magnetic resonance imaging-based prostatic tissue morphology and changes in International Prostate Symptom Score and maximum urinary flow rate after prostatic artery embolization

Baseline MRI-defined prostate morphology, assessed primarily on T2WIs, was significantly associated with clinical outcomes after PAE; glandular-dominant morphology was linked to larger and more sustained improvements in both the Qmax and IPSS. Therefore, MRI-based phenotypes offer a practical imaging biomarker for patient stratification, warranting prospective validation.
