Intra-Voxel Incoherent Motion (IVIM), PET imaging, and Amide Proton Transfer weighted imaging (APTw) are all effective tools for distinguishing the pathological types of solitary pulmonary lesions. The difference between their ability to distinguish the Ki-67 high expression (HE) and low expression (LE) group is still unclear. Our study shows IVIM and PET imaging are better methods than APTw for distinguishing Ki-67 HE and LE groups of non-small cell cancer.
