Discouraging MRI Report
Not the MRI I was hoping for……and words of advice. I’ve gone from a pirads 2 with no lesions to this in one year. PSA currently 8.8. Feeling a little devastated after all my efforts seem to have failed.
Impression
IMPRESSION: 1. At least 4 regions of concern on a background of relatively diffuse signal abnormality of the peripheral gland of the prostate, with the highest PI-RADS category: 5. 2. No pelvic lymphadenopathy by size criteria. 3. Additional chronic findings as described. PI-RADS v2.1 is designed to predict the probability of a cancer which is deemed clinically significant as defined by: pathology/histology Gleason score greater than or equal to 7 (including 3+4 with prominent but not predominant Gleason 4 component), and/or volume greater than 0.5cc, and/or extraprostatic extension (EPE). PI-RADS v2.1 Assessment Categories: PI-RADS 1: Very low (clinically significant cancer is highly unlikely to be present) PI-RADS 2: Low (clinically significant cancer is unlikely to present) PI-RADS 3: Indeterminate (the presence of clinically significant cancer is equivocal) PI-RADS 4: High (clinically significant cancers likely to be present) PI-RADS 5: Very high (clinically significant is highly likely to be present) http://www.acr.org/Quality-Safety/Resources/PIRADS/ Dictated by: Will G Larison, M.D. on 9/22/2026 9:08 AM PDT Electronically signed by: Will G Larison, M.D. on 9/22/2026 9:33 AM PDT
Narrative
MRI PROSTATE W WO CONTRAST CLINICAL INFORMATION: Elevated PSA. COMPARISON: 10/6/2025 TECHNIQUE: Multiplanar multisequence 3T MR imaging of the pelvis performed without and with intravenous contrast utilizing the prostate protocol. Dynamic contrast enhanced series as well as multiple B-value diffusion-weighted series with ADC mapping were acquired. CONTRAST: 9 mL of intravenous Gadavist (Gadobutrol). FINDINGS: LIMITATIONS: None. PROSTATE Size: 4.1 x 6.2 x 6.3 cm. Volume: 83 mL based on ellipsoid calculation. Central Gland BPH Changes: Moderate with large median lobe. Pre-Contrast T1 Changes (Blood): Absent. LESIONS: Persistent signal abnormality throughout the bulk of the peripheral gland now with suspected regions of superimposed concern as described below. LESION # 1. Best seen on series 7 image # 23. Location: Peripheral zone within the mid gland at the 5 o'clock position. Size: 1.1 cm. T2 Characteristics & Score: The lesion demonstrates a T2 score of Peripheral Zone 4: Circumscribed, homogeneous moderately hypointense focus confined to prostate and less than 1.5 cm in greatest dimension. DWI Characteristics & Score: The lesion demonstrates a DWI score of 3: Focal hypointensity on ADC and/or focal hyperintensity on high b-value DWI. Dynamic contrast enhancement: (+ ): Focal, and earlier than enhancement of adjacent normal prostatic tissues, corresponding to suspicious finding on T2W/DWI. LESION PI-RADS CATEGORY: PI-RADS 4 - High (clinically significant cancer is likely to be present) LESION # 2. Best seen on series 7 image # 23. Location: Peripheral zone within the mid gland at the 7-8 o'clock position. Size: 1.4 cm. T2 Characteristics & Score: The lesion demonstrates a T2 score of Peripheral Zone 4: Circumscribed, homogeneous moderately hypointense focus confined to prostate and less than 1.5 cm in greatest dimension. DWI Characteristics & Score: The lesion demonstrates a DWI score of 4: Focal marked hypointensity on ADC and marked hyperintensity on high b-value DWI; measuring less than 1.5 cm in greatest dimension. Dynamic contrast enhancement: (+ ): Focal, and earlier than enhancement of adjacent normal prostatic tissues, corresponding to suspicious finding on T2W/DWI. LESION PI-RADS CATEGORY: PI-RADS 4 - High (clinically significant cancer is likely to be present) LESION # 3. Best seen on series 7 image # 16. Location: Peripheral zone within the base at the 7 o'clock position. Size: 2.1 cm. T2 Characteristics & Score: The lesion demonstrates a T2 score of Peripheral Zone 3: Heterogeneous signal intensity or non-circumscribed, rounded, moderate hypointensity; Includes others that do not qualify as 2, 4, or 5. DWI Characteristics & Score: The lesion demonstrates a DWI score of 5: Focal marked hypointensity on ADC and marked hyperintensity on high b-value DWI; measuring at least 1.5 cm in greatest dimension or demonstrating definite extraprostatic extension. Dynamic contrast enhancement: (+ ): Focal, and earlier than enhancement of adjacent normal prostatic tissues, corresponding to suspicious finding on T2W/DWI. LESION PI-RADS CATEGORY: PI-RADS 5 - Very High (clinically significant cancer is highly likely to be present) LESION # 4. Best seen on series 7 image # 22. Location: Peripheral zone within the apex at the 3 o'clock position. Size: 1.7 cm. T2 Characteristics & Score: The lesion demonstrates a T2 score of Peripheral Zone 3: Heterogeneous signal intensity or non-circumscribed, rounded, moderate hypointensity; Includes others that do not qualify as 2, 4, or 5. DWI Characteristics & Score: The lesion demonstrates a DWI score of 5: Focal marked hypointensity on ADC and marked hyperintensity on high b-value DWI; measuring at least 1.5 cm in greatest dimension or demonstrating definite extraprostatic extension. Dynamic contrast enhancement: (+ ): Focal, and earlier than enhancement of adjacent normal prostatic tissues, corresponding to suspicious finding on T2W/DWI. LESION PI-RADS CATEGORY: PI-RADS 5 - Very High (clinically significant cancer is highly likely to be present) Prostate margin: EPE: Threatened. Local invasion: No local invasion identified. Pelvic Lymph Nodes: No lymphadenopathy by size criteria. Bowel: Colonic diverticulosis. The imaged small bowel and colon is otherwise normal. Bladder: Thickening and trabeculation of the urinary bladder, often seen in the setting of chronic bladder outlet obstruction physiology. Left ureterocele again demonstrated. Abdominal Wall & Pelvic Girdle soft tissues: Bilateral fat-containing inguinal hernias. Bones: No acute or suspicious lesion. Other: No ascites.

1 ReactionInteresting. I just did this with my MRI report. Gives you more information and a better understand of what is going on.

Just want to chime in here to say that although it seems like many people here extol transperineal over transrectal biopsies, I had mine done the latter way about a year ago at a local center of excellence, and it really wasn't bad at all, and I was able to just drive myself home as there was no general involved. If you feel like you'd like to take care of this, just go ahead with that approach. Also, yes, you're best to not assume the worst, and wait until you have all the information available before arriving at conclusions.
Best of luck!

4 Reactions@sorensend58 So here’s the weird thing: your PSA places you in the aggressive category, yet Artera says no need for ADT…who’s correct??
Can you have an aggressive cancer with a low chance for metastasis?🤔
All these different standards and categories can make you nuts!

3 Reactions@sandguy In my case with 4 lesions in different places all Pirads 5 and 4 and threatening EPE a MRI fusion is needed to get most accurate cancer grade and gleason score. Hopefully that justifies the additional wait for one.

1 Reaction@heavyphil All the standards, all the acronyms, all the numbers. There are even more things to look at when you start down this rabbit hole. You look at the PSA doubling rate, Sloan Kettering has a nomogram where you plug in your dates and PSA. If I looked at mine 2024 was 8, 3 tests this year, april 11, June 19, 3 days ago 23, if you plug in just april and june, doubling rate of 2 months, you plug in june to september doubling rate of 54 months, plug in all of them doubling of 20 months. Then throw in that an increase may or may not indicate cells outside the prostate. So now you can go to another nomogram Briganti which you plug in a bunch of numbers and it gives you a percentage chance that there is something that is outside the prostate that wasn't picked up on the Pet scan and it shows a 3.3% chance. You can drive yourself nuts, but at this point where I'm at right now is to see how much weight the Radiologist puts in any of these "clues" because that's what they are, they are nothing more than here are averages or studies that indicate if you do X then Y happens. The one sure thing that I know is that everyone is different and I'm glad I'm going to the Mayo Clinic, I need to see what the "real experts" have to say in my specific case.

1 Reaction@sorensend58 I would agree. You can drive yourself nuts crunching all the numbers and data and forget to live your life. That’s where I’m at.
@ezupcic
The PSA may not matter at all, or it may be really important. If the PSA is above 20 That is considered more aggressive. Of course Mayo Clinic says they’ve had PSA’s up to 20,000 so 20 doesn’t seem too high. I’ve been to meetings where people had PSA’ s in the thousands, but treatment got them back down.
If you have four lesions that are rated that high, you really need a biopsy. Until you get that biopsy, you won’t really know for sure How aggressive your case is.
Some people don’t produce any PSA at all so 8.8 is significant enough to want to do a biopsy when you have all those PIRADS 4 and 5.

2 Reactions@jeffmarc I agree. My next challenge is to decide whether to do a standard transrectal 12 core office biopsy in one month or a MRI fusion transpareneally with a delay of 8-10 weeks. I’m definitely worried about the “threatening EPE” observation in my MRI.

The advantage of the Transperineal Is that there’s a slightly lower chance of infection and they can get to more of the prostate.
I might want to find out more about what’s going on sooner. That is a very long wait, though prostate cancer does usually grow very slowly. If you must wait that long, you could ask about having ADT, Not the most fun, but can stop the cancer from growing and spreading.
Just bringing these up as possibilities not something you really have to do.
