Outline of Final Research Achievements

Purpose: Intravoxel incoherent motion (IVIM) MR imaging provides data on both true molecular diffusion and incoherent motion of water molecules in the capillary network without of application of contrast medium. The purpose of this study was to evaluate the usefulness of IVIM MRI in assessment of cervical lymphadenopathy. Materials and methods: The Patients with cervical lymphadenopathy caused by a varied etiology were examined using IVIM MRI. We evaluated the diffusion-related parameters and perfusion-related parameters of the respective lymph nodes. Results and conclusions: It was confirmed that IVIM MRI was helpful in differentiating between metastatic and non-metastatic nodes and between malignant lymphoma and SCC nodes.
