Wen JB, et al. - This work was planned to ascertain the diagnostic performance of diffusion-weighted imaging, the relative minimum apparent diffusion coefficient (rADCmin) in differentiating primary central nervous system lymphomas (PCNSLs) from glioblastomas (GBMs) and inflammatory demyelinating pseudotumors (IDPs). Researchers recognized the relative ADCmin value as effective in differentiating PCNSL from GBM and IDP. Thus, it seems that ADC values could provide a useful supplement to the information obtained from conventional contrast-enhanced magnetic resonance imaging and assist in future treatment planning.
