Synopsis

Keywords: Quantitative Imaging, Neurography

We assess the ability of a novel single-shot quantitative T2 magnetic resonance imaging (MRI) sequence and apparent diffusion coefficient (ADC) maps in predicting the WHO grade in meningiomas. We used histogram analysis of T2 maps and ADC maps to compare different grades of meningioma. ADC P10 proved to be the best predictor among all histogram parameters of ADC. While histogram analysis of T2 maps did not receive satisfactory results, the combination of T2 kurtosis and ADC P10 proved to be the best predictor. It is worthy of consideration to try another method of ROI placement and increase the sample size.
