Triple-phase contrast-enhanced MRI for the prediction of preoperative chemotherapeutic effect in patients with osteosarcoma: comparison with 99m Tc-MIBI scintigraphy

Objective This study aims to determine whether 99mTc-MIBI scintigraphy and triple-phase contrast-enhanced magnetic resonance imaging (TCE-MRI) performed during and after preoperative chemotherapy have the power to predict final chemotherapeutic effects in patients with osteosarcoma (OS).
