Preoperatively Grading Rectal Cancer with the Combination of Intravoxel Incoherent Motions Imaging and Diffusion Kurtosis Imaging

Figure 1

MR images of patients with surgically proven rectal cancer of WHO G1 (a–f) and WHO G3 (g–l). A patient of WHO G1 rectal cancer: (a) T2-weighted image, (b) D_app image, (c) K_app image, (d) D image, (e) f image, and (f) D image. A patient of WHO G3 rectal cancer: (g) T2-weighted image, (h) D_app image, (i) K_app image, (j) D image, (k) f image, and (l) D image. Note. The unit of D D and D_app: ×10⁻⁹ m²/s; K_app and f are unitless.
