 MKEE-3 — 2024 RSNA MR NEUROGRAPHY OF FINE-CALIBER NERVES: A CASE-BASED REVIEW Musculoskeletal Imaging MKEE | Musculoskeletal Imaging Education Exhibits Presented on Thursday, December 5, 2024 7:30 AM Author: Niels Vinicius Padua Carvalho, MD *Teaching Points: The analysis of fine-caliber peripheral nerves using imaging methods is a challenging task. However, recent advances enabled higher resolution, thinner sequences with multiplanar reformatting, making it feasible to evaluate these very thin nerves using MR neurography (MRN). Therefore, MRN has been used to: (1) exclude the diagnosis of peripheral neuropathy by displaying normal nerves and regional muscles; (2) confirm suspicion of peripheral neuropathy by directly showing the nerve abnormality or regional muscle denervation changes by depicting the lesions causing nerve entrapment or impingement; (3) assess the extent of the abnormality or the disease load; (4) detect incidental lesions in the region of interest that mimic neuropathy symptoms; (5) provide imaging guidance treatments. We aim to demonstrate through cases collect in our institution the evaluation of multiple neuropathies, reinforcing its role as an important tool to access the small caliber peripheral nerves. *Table of Contents/Outline: (1) Peripheral nerves: concepts and anatomy, focusing on fine-caliber nerves; (2) Neuropathy: imaging findings and diagnostic challenges- Role of MRN; (3) Review through cases from our service, with literature review, including, but not limited to: (3.1) Intercostal neuropathy; (3.2) Long thoracic nerve; (3.3) Accessory nerve; (3.4) Suprascapular nerve; (3.5) Palmar cutaneous branch of the median nerve; (3.6) Medial cutaneous nerve of the forearm; (3.7) Digital nerve; (3.8) Genitofemoral nerve; (3.9) Superior gluteal nerve; (3.10) Obturator nerve; (3.11) Ilioinguinal nerve; (3.12) Medial plantar nerve...
