Abstract:
Objective To investigate the correlation between minimum apparent diffusion coefficient ( ADC) values and consistency of intracranial meningiomas of different parts and nature, providing radiographic evidence of selection for surgical approach. Methods The routine MRI, diffusion-weighted imaging imaging (DWI), ADC maps and ADC value of 23 patients (25 cases) who were confirmed as men-ingiomas through surgery and pathology were retrospectively analyzed and compared with the surgical findings and pathology results. Results ADC values in meningiomas with a hard consistency were significantly lower than those with a soft consistency. Meningiomas with low mini-mum ADC were considered to have a hard consistency. Conclusion The consistency of meningiomas is an important factor in developing the strategy of surgical resection and predicting the degree of removal. The minimum ADC value might have clinical use as a predictor of menin-gioma consistency.
