Magnetic resonance (MR) perfusion techniques and MR spectroscopy (MRS) provide specific physiological information that may allow distinction between recurrent glioma and progression from stable disease. ⋯ MR perfusion techniques and MRS are useful tools that enable improved differentiation between recurrent glioma and stable disease. Among the single parameters, DSC showed the best diagnostic performance. Multiparametric assessment substantially improved the ability to differentiate the two entities.

To investigate the relationship between apparent diffusion coefficient (ADC) values and the Ki-67 staining index (Ki-67 SI), a tumor proliferation marker, in prostate cancer (PCa). ⋯ The ADC values of PCa could reflect the tumor proliferative activity and the differentiated degree of PCa.
