Motivation: To promote a non-invasive method to evaluate the radiation induced femoral head changes.
Goal(s): To investigate the value of MRI texture analysis for evaluating radiation induced femoral head changes in rectal cancer patients after radiotherapy.
Approach: The texture parameters of T1WI, T2WI and DWI images were extracted in femoral head. And the differences of texture parameters before and after radiotherapy were compared.
Results: We found that when combined the texture parameters of T1WI, T2WI and DWI images, the diagnostic efficiency of femoral head changes was optimal with AUC of 0.85 (sensitivity,0.81; specificity,0.80).
Impact: MRI texture analysis may provide a non-invasive method to evaluate the radiation induced femoral head changes, providing imaging clues for monitoring the potential radiation-induced femoral head injury.
