Xu C, et al. - A multi-parameter study was conducted to assess the value of integrated multi-parameter positron emission tomography-intravoxel incoherent motion magnetic resonance (PET-IVIM MR) imaging for pelvic lymph nodes with high FDG uptake in cervical cancer, and to determine the best combination of parameters. Researchers recruited a sum of 38 individuals with 59 lymph nodes with high FDG uptake. The PET-IVIM MR measured the imaging parameters of the lymph nodes, and the differences between lymph nodes diagnosed by postoperative pathology as metastasis vs non-metastasis were compared. Compared with PET- or IVIM-derived parameters either in combination or individually, the combination of MTV, SUVmax, and D may have a better diagnostic performance. There was no strong relationship between diffusion parameters and metabolic parameters.
