Concurrent Chemoradiotherapy-induced Pelvic Bone Marrow Changes Based on Intravoxel Incoherent Motion MR imaging in Patients with Cervical Cancer: Initial Findings

Sixteen patients with cervical cancers underwent intravoxel incoherent motion (IVIM) imaging with 13 b values (0~1,000 s/mm2) on a 3 T MR scanner before, 2 and 4 weeks after start of concurrent chemoradiotherapy (CCRT). D and ADC values of bone marrows within the radiation field (RF) increased significantly at 2 weeks and then returned to baseline levels at 4 weeks. f values of bone marrows within the RF increased significantly at 2 weeks and continued to increase at 4 weeks. Parameters of bone marrow outside the RF and gluteus remained unchanged.
