History
- 63 y/o, PSA 8.8 → 13.2 over 5 years
- All systematic biopsies negative
- Hypointense left anterior lesion with restricted diffusion is moderately suspicious, not in biopsy zone
Imaging
LEFT: Axial T2-weighted image: asymmetric anterior low signal
RIGHT: Apparent diffusion coefficient (ADC) map: focal restricted diffusion
LEFT: Oblique Axial T2-weighted image from in-bore MR-guided targeting
RIGHT: Corresponding sagittal T2-weighted image from in-bore MR-guided targeting
Results
- Gleason grade 3+3=6/10
- All biopsies over 5 mm and over 50% of core
Advantage: UCLA Prostate MRI
Suspicious findings on diagnostic multiparametric prostate MRI can be targeted for direct in-bore MRI-guided biopsy or MRI-ultrasound fusion targeted biopsy
