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

Figure 5

Diagnostic performance evaluation. (a) Diagnosis of high-grade rectal cancer with single DWI-derived biological insight-based parameters including cellularity (D and D_app) and vascularity f together with microstructural complexity (K_app). (b) Diagnosis of high-grade rectal cancer with the combinations of different DWI inspirations including cellularity and vascularity (D and f, cellularity and microstructural complexity (D and K_app), vascularity and microstructural complexity (f and K_app), and cellularity and vascularity and microstructural complexity (D and f and K_app).
