Diffusion magnetic resonance imaging: A molecular imaging tool caught between hope, hype and the real world of “personalized oncology”

Figure 6 A 62-year-old male presented with bleeding per rectum. (A) Axial post contrast T1W fat suppressed image showed eccentric rectal wall thickening (arrow) which showed restricted diffusion (B) on diffusion weighted images (ROI 1) with reduced ADC values (C) as compared to the adjacent normal rectal wall (ROI 2). Histopathological evaluation revealed adenocarcinoma of rectum.
