Diffusion Kurtosis Imaging as a Prognostic Marker in Osteosarcoma Patients with Preoperative Chemotherapy
Figure 2
Kaplan-Meier survival curve for overall survival (a–d) and progression-free survival in osteosarcoma patients. Patients with greater than 90% tumor necrosis, high post MD, low post MK, or high CR MD had a significantly better OS and PFS. Post MK: mean kurtosis after neoadjuvant chemotherapy; post MD: mean kurtosis after neoadjuvant chemotherapy; CR MD: change rate in mean kurtosis in mean diffusivity. MD is given in .
