My MRI report is below. Not sure if I should do another PSA test soon or wait 6 months for another MRI. Any thoughts appreciated.

HISTORY: Prostate specific antigen above reference range R97.20: Elevated prostate specific antigen (PSA)

COMPARISON: None.

TECHNIQUE: Multiplanar multisequence MR imaging of the pelvis performed without and with intravenous contrast using the prostate protocol. Multiple B-value diffusion-weighted imaging in the axial plane was also performed through the prostate gland with
ADC mapping.

IV Gadavist 10 mL.

FINDINGS:

PROSTATE VOLUME: 6.8 x 4.29 x 6.1 cm with a prostate volume 95 mL.

PERIPHERAL ZONE: Diffuse abnormality of the peripheral zone noted characterized by low T2-weighted signal and mildly elevated diffusion-weighted signal and mildly decreased ADC signal without focal lesions. The capsule is well defined.

TRANSITION/CENTRAL ZONE: Diffuse nodular transition zone noted

OTHER PELVIS: No pelvic adenopathy identified. The seminal vesicles appear symmetric. The bladder appears normal.
Impression
IMPRESSION:

Diffuse abnormality the peripheral zone. This is a nonspecific finding and can be seen in both acute and chronic prostatitis or other inflammatory process and rarely in diffuse malignancy. Malignancy being considered less likely in the presence of
a well-defined capsule. Consider follow-up MRI in 6 months.

FINAL PI-RADS: 3, intermediate. The presence of clinically significant cancer is equivocal.
