Assessment of Resection Margins in Bone Tumor Surgery

Figure 2

A 9-year-old girl with osteosarcoma of the distal radius. A step-cut was performed proximally for the stability of surgical reconstruction by using a PSI. Two margins were measured (medial and lateral part of the step-cut). Note the difficulty to visualize the cortical bone in the step-cut with MRI. (a) T1-weighted MRI; (b) macroscopic cut; (c) T2-weighted MRI.
