Overview
MRI is used for for evaluation of primary tumor and its invasion. MRI is used for diagnosis of primary location of rhabdomyosarcoma located in head and neck, paraspinal, parameningeal regions, extremities, and pelvic tumors. MRI features in rhabdomyosarcoma are characterized by low to intermediate intensity on T1, hyperintense on T2, and considerable contrast enhancement on T1 contrast.
