PDFAbstract
Objective To explore the apparent diffusion coefficient(ADC), relative blood flow(r CBF) and relative blood volume(r CBFV) in diagnosis of primary central nervous system lymphoma(PCNSL) and glioblastoma multiforme(GBM), in order to improve the accuracy of the diagnosis of both diseases. Methods The MRI data of 93 cases were selected in histologically confirmed with PCNSL and GBM. By choosing the dynamic contrast enhanced image in post-processing software. And measurement and analysis of the ADC, r CBF, and r CBFV. Results The lesion of PCNSL was signal even, restricted diffusion, enhancement or heterogenous enhancement, and peripheral edema. The apparent diffusion coefficient of PCNSL less than the GBM, and the difference was statistically significant(P＜0.05). The PCNSL of r CBF and r CBFV of is less than the GBM, and the difference was statistically significant(P＜0.05). Conclusion According to the apparent diffusion coefficient, r CBF and r CBFV could efficient identification the PCNSL and GBM. Clinical differential diagnosis of PCNSL and GBM has important clinical implications, will improve the accuracy of diagnosis of PCNSL and GBM.
