SLIC-supervoxels-based response evaluation of osteosarcoma treated with neoadjuvant chemotherapy using multi-parametric MR imaging

ConclusionThe proposed multiparametric MRI-based SLICs+MTh method performs noninvasive assessment of NACT response in osteosarcoma that may improve cancer treatment monitoring, planning, and overall prognosis.Key Points• The simple linear iterative clustering supervoxels and Otsu multithresholding-based technique (SLICs+MTh) successfully estimates the proportion of necrosis, viable tumor, and edema in osteosarcoma in the course of chemotherapy.• The proposed technique is noninvasive and uses multiparametric MRI to measure necrosis as an indication of anticancer treatment response.• SLICs+MTh-based necrosis was in satisfactory agreement with histological necrosis after surgery.
