MRI can display the compositions of different tissues and adjacent involvements. In the patients of bone tumors, the integrity of cortical bone needed to be assessed for the preoperative planning. This study used proton density ZTE to display the bone involvement in patients of femoral tumors. Substantial agreement was found between CT and ZTE (r=0.98-0.99) and there was not statics significance between the measured diameters from CT and ZTE MRI (p=0.34-0.99). further development of ZTE may obviate the need of CT in evaluating the bone involvement of femoral tumors.
