[Advancements in Magnetic Resonance Neurography: Techniques, Sequences, and Standardization].

Magnetic resonance neurography requires varying imaging techniques based on the site of imaging and anticipated disease. In assessing the brachial and lumbosacral plexus, a three-dimensional (3D) spin echo method, such as 3D-short tau inversion recovery imaging, is frequently employed. It's beneficial to familiarize oneself with the imaging sequence and understand the appearance of normal images in advance. The imaging parameters used in our institute are provided below as a reference. When interpreting the images, pay close attention to nerve thickening, signal intensity changes, asymmetry between the left and right sides, and irregularities in nerve caliber. Efforts are underway to standardize qualitative assessments and quantify signals through technological advancements.
