Fig. 4.
MR images of an implanted breast cancer (MDA-MB-231) xenograft model. (a) T2W image, (b) DWI, (c, d) sADC maps with short diffusion time (9.6 ms) and long diffusion time (27.6 ms), and (e) sADC change map. Arrow on T2W image indicates the tumor (13.4 mm in diameter). The tumor shows relatively high (yellow-green) sADC at the short diffusion time and low (blue) sADC at the long diffusion time. In contrast, muscle shows high (red-yellow) sADC at both diffusion times. The sADC change in the tumor is striking, while there is very little sADC change in the muscle.
