It is of significant clinical importance to differentiate between Tumefactive demyelinating lesions (TDLs)and high-grade gliomas(HGGs) to avoid surgical biopsy. However, this goal is difficult to achieve by conventional MR imaging alone. The objective of our study is to determine retrospectively whether quantitative histogram analysis of FA and MD values can be helpful in distinguishing between TDLs and HGGs. We compare the FA value and MD value for both enhanced Tumefactive demyelinating lesions(TDLs) and enhanced high grade glioma(HGGs) with the matched location. Results showed that TDLs and HGGs could be differentiated by using the histogram method.
