Objective To investigate the clinical value of MRI in the diagnosis of intracranial meningioma. Methods Retrospective analysis of MRI data of 96 patients with meningioma confirmed by surgery and pathology in our hospital from January 2014 to December 2015. And comprehensive analysis of the lesion size, location, morphology and other MRI imaging features, detection rate and pathological characteristics of patients with meningioma. Results 96 cases of patients with meningioma were solitary tumors. The tumor located in the top convexity, anterior skull base, middle cranial fossa, after skull base, falx patients respectively was 39 cases, 23 cases, 18 cases, 10 cases, 6 cases. The detection rate of MRI in this group was 91.7%, which was confirmed by surgery and pathology. Tumor shape is round or oval, half moon shape, diameter between 3-5cm, size between 1.2cm×1.0 cm×1.3 cm to 6.2 cm×4.6 cm×6.1cm. T1WI was in 58 cases, showed slightly low signal in 29 cases, 9 cases showed mixed uneven signal; T2WI was slightly high signal in 46 cases, 21 cases showed signal, 21 cases showed low signal, 8 cases showed mixed signal. After enhanced scanning, 88 cases were obviously enhanced, and 8 cases were inhomogeneous enhancement. Around 38 cases of tumors showed edema, 63 cases of tumor in T1WI showed hypointense, 27 cases of partial calvarial thickening. Conclusion MRI in the diagnosis of meningioma, not only to locate the location and size of the tumor diagnosis, size, shape, but also through the comprehensive analysis of the MRI imaging manifestations and pathological features of the qualitative diagnosis, has important clinical application value. It is worthy of further promotion and application.
