Objective To explore the CT and MRI in the diagnosis of primary central nervous system lymphoma (PCNSL) and the CT and MRI imaging characteristics of PCNSL. Methods Select confirmed by our hospital pathology and clinical 78 cases of PCNSL patients as the research object, all the patients were row multislice CT and MRI scan and enhanced scan, observation of CT and MRI imaging characteristics of lymphoma, the tumor nature, tumor weeks edema area to 1H-MRS and ADC values compared with the contralateral area. Results CT and MRI showed that PCNSL lesions of good hair parts including the frontal, parietal lobe and basal ganglia region; PCNSL CT images mainly for or slightly high density, such as MRI image is mainly or slightly long T1, or slightly long T2 signals, such as DWI is high, can slightly higher or high signal, tumors are in obvious strengthening the essence; Tumor parenchyma area Cho/NAA, Cho/Cr, Lip/ Cr significantly higher than the tumor weeks edema zone and the contralateral control area, NAA/Cr and ADC significantly lower than the tumor weeks edema area and the contralateral control area (P<0.05). Conclusion In the diagnosis of PCNSL, MDCT, MRI has high value, can be clearly shows that the tumor shape, density and metabolism, and the diagnostic value of MRI is higher.
