MKI67 and neoplasm: We found no correlation between overall tumor consistency and presence of general tumor heterogeneity on T2, DWI signal, tumor capsule, tumor surface, invasion of bone or dural sinus, vascularity, PTE volume, WHO grade, or Simpson resection grade.Tumor grade correlated moderately with Ki-67 count (r = 0.4, p = 0.007), but was not correlated to tumor consistency (r = 0.08, p = 0.5).
