An 18F-FDG PET/3D-UTE MRI-based radiomics model facilitates the preoperative assessment of lymph node status in non-small cell lung cancer

18F-FDG PET/MRI is one of the most advanced means for the noninvasive diagnosis and evaluation of tumors. Three-dimensional ultrashort echo time (3D-UTE) is a novel MRI technique, which not only does not have ionizing radiation but also yields similar diagnostic results as conventional pulmonary CT. Our results showed that the 18F-FDG PET/MRI model based on clinical factors, 3D-UTE, and PET radiomics features could noninvasively assess the lymph node status in non-small cell lung cancer(NSCLC). Compared with the PET/CT model, it has similar diagnostic efficiency but less radiation, which is expected to provide new ideas for related research.
