Figure 1. Patient with prostate cancer: malignant peripheral zone (PZ, black arrows) identified as a low signal-intensity region on conventional T2 weighted image (a) with the low signal-intensity central gland (CG; arrowhead) and high signal-intensity non-malignant PZ (white arrow) clearly identified. Regions of interest outlining the malignant nodule, CG and non-malignant PZ are shown in (b). The malignant nodule is seen as focal area of restricted diffusion (arrow) on (c) the apparent diffusion coefficient (ADC) map.
