Radiologic Imaging of Neuroma

High-resolution peripheral nerve imaging, either with MR neurography or US, provides a noninvasive means to directly visualize peripheral nerves. Imaging helps to characterize the location and extent of neuroma formation, which may obviate the need for a more extensive nerve exploration, potentially decreasing operating room time and postoperative morbidity. MR neurography and US are often complementary. MRI provides superior soft tissue contrast resolution and facilitates imaging of deeper nerves. US generally provides superior spatial resolution for superficial structures. Both modalities rely on experienced technologists and specialty-trained radiologists to obtain optimal imaging for the diagnosis and localization of symptomatic neuromas.
