MKI67 and neoplasm: On the other hand, poor and statistically insignificant correlations were observed between SUVmax values and tumor volume determined with PET/MRI (r = 0.309, p = 0.172), tumor volume determined with CT (r = 0.289, p = 0.203), Ki67 index (r = 0.04, p = 0.862), CRP concentration (r = 0.069, p = 0.764) and glucose levels (r = 0.308, p = 0.173).
