Varying diffusion curvature, intravoxel incoherent motion, and conventional monoexponential diffusion models for evaluating Ki-67 expression in rectal carcinoma
This study aimed to systematically evaluate and compare the diagnostic performance of three diffusion models — varying diffusion curvature (VDC), intravoxel incoherent motion (IVIM), and conventional monoexponential diffusion-weighted imaging (DWI) — in predicting Ki-67 expression status in rectal adenocarcinoma....
