@jeffmarc according to AI......"you don't need a discrete lesion to have a Pi-Rads category. A prostate MRI with no focal suspicious findings can still be reported as a Pi-Rads 1 (normal) or Pi-Rads 2 (benign appearing changes).

@ezupcic here was the impression from the radiologist
IMPRESSION:
1. Persistent relatively diffuse signal abnormality throughout the
peripheral gland of the prostate typically representative of
prostatitis without discrete suspicious underlying lesion identified,
with the highest PI-RADS category: 2. Diffuse
neoplastic involvement remains of consideration but felt
significantly less likely given appearance.
2. Prostatomegaly as described.
3. Sequela of chronic bladder outlet obstruction physiology, left
sided ureterocele, colonic diverticulosis, and bilateral
fat-containing inguinal hernias.

@ezupcic
What you say is true, a lesion is not necessarily there, but there is a specific area abnormality found to get a PIRADS 2 score, So that could be targeted in a biopsy just like a lesion.

AI says the following

Yes, a PI-RADS 2 score indicates a low probability of clinically significant cancer, but it's assigned to specific suspicious lesions or areas (like linear/wedge-shaped abnormalities in the peripheral zone, often from prostatitis) that have certain characteristics, not just a completely normal prostate, though a score of 1 is very low likelihood, and PI-RADS 1 or 2 often means deferring biopsy. You need to have a focal finding (a "lesion") that meets PI-RADS 2 criteria for that specific score to be given, rather than just a "normal" scan, which would be a PI-RADS 1.
