Objective To investigate the neuroimaging characteristics of intracranial ring-enhancing lesions and the value of multimodal magnetic resonance imaging （MRI） in the diagnosis of such lesions.Methods A retrospective analysis was performed for the clinical data of 67 patients with intracranial ring-enhancing lesions who were treated in Third Xiangya Hospital， Central South University， from January 2015 to January 2023 and underwent multimodal MRI， including imaging characteristics， imaging diagnosis， report of clinical confirmed diagnosis， and prognosis.Results Among the 67 patients with intracranial ring-enhancing lesions， there were 26 patients with glioma， 20 patients with metastatic tumors， 7 patients with encephalopyosis， 5 patients with demyelinating lesions， 3 patients with lymphomas， and 6 patients with other diseases. Although conventional MRI sequences （T1WI， T2WI， FIAIR， and contrast-enhanced examination） can clearly display the location and shape of ring-enhancing lesions and the degree of perifocal edema， it is difficult to make a qualitative diagnosis. With reference to the imaging characteristics of other multimodal magnetic resonance sequences （such as MRS， DWI， and PWI） and the construction of a flow chart for imaging differential diagnosis， a relatively clear imaging diagnosis was made for 57 patients， among whom 54 patients had an imaging diagnosis consistent with the final clinical diagnosis.Conclusion Multimodal magnetic resonance techniques （including MRS， DWI， and PWI） significantly improve the accuracy of imaging diagnosis by analyzing the pathophysiological characteristics of intracranial ring-enhancing lesions in combination with the programmed differential diagnostic analysis.
