Figure 4. Clinical stage T1c prostate cancer, Gleason grade 3+3. (a) Axial T2 weighted MR image shows foci of low-signal-intensity areas in the right and left sides of the peripheral zone. The tumour is organ-confined. In the region of cancer, MR spectra (b) show that citrate, although decreased, is still present, while choline is moderately elevated, indicating low-grade tumour. (c) Step-section pathology shows scattered organ-confined disease and confirms Gleason grade 3+3, pT2b.
