Feasibility of multi-parametric magnetic resonance imaging combined with machine learning in the assessment of necrosis of osteosarcoma after neoadjuvant chemotherapy: a preliminary study

Abstract: Background: Response evaluation of neoadjuvant chemotherapy (NACT) in patients with osteosarcoma is significant for the termination of ineffective treatment, the development of postoperative chemotherapy regimens, and the prediction of prognosis. However, histological response and tumour necrosis rate can currently be evaluated only in resected specimens after NACT. A preoperatively accurate, noninvasive, and reproducible method of response assessment to NACT is required. In this study, the value of multi-para… Show more

“…In the second stage (clearance stage), higher WOR values correspond to higher vascular permeability and indicate rapid excretion of contrast agents. SI max , SEE, PPE, and R values reflect the overall vascular density and permeability of the tumors, and higher values indicate richer blood flow [ 11 , 22 , 23 ].…”

“…However, it provided insights for the design and reporting radiomics studies. Second, our study only included AI research applying the radiomics approach, but overlooked those conducted with only deep learning for segmentation [60][61][62] or modeling [63]. However, the secondary aim of our study is to find out whether CLAIM can better identify disadvantages in radiomics studies than the currently recommended RQS and TRIPOD.…”

“…In 2020, a preliminary study conducted by Huang et al. applied ML to predict tumor necrosis rate on multiparametric MRI before and after chemotherapy in patients with osteosarcoma ( 103 ). This study is of great significance since it first explored the potential correlation between contrast-enhanced MRI and postoperative pathological features.…”

“…Early identification of lung metastasis is critical for alleviating prognosis and treatment of patients ( 127 ). Recently, deep learning approaches have been applied to detect and classify lung metastasis and build deep learning-based image reconstruction techniques ( 128 , 129 ) that can significantly reduce the radiation dose of CT ( 103 ). Due to the crucial role of lung metastasis detection for prognosis in malignant bone tumors, more efficient models are expected to be developed.…”
