“…Many techniques including MRI myelography, MR neurography, and DTI can be combined for additional data, for example in root avulsions in patients with brachial plexus injuries, [43] but in order for the higher sequences to be carried out, greater acquisition times are required.…”

Peripheral nerve injuries are a heterogeneous group of lesions that may occurs secondary to\ud various causes. Several different classifications have been used to describe the pathophysiological\ud mechanisms leading to the clinical deficit, from simple and reversible compression‑induced\ud demyelination, to complete transection of nerve axons. Neurophysiological data localize, quantify,\ud and qualify (demyelination vs. axonal loss) the clinical and subclinical deficits. High‑resolution\ud ultrasound can demonstrate the morphological extent of nerve damage, fascicular echotexture\ud (epineurium vs. perineurium, focal alteration of the cross‑section of the nerve, any neuromas, etc.),\ud and the surrounding tissues. High field magnetic resonance imaging provides high contrast\ud neurography by fat suppression sequences and shows structural connectivity through the use\ud of diffusion‑weighted sequences. The aim of this review is to provide clinical guidelines for the\ud diagnosis of nerve injuries, and the rationale for instrumental evaluation in the preoperative and\ud postoperative periods. While history and clinical approach guide neurophysiological examination,\ud nerve conduction and electromyography studies provide functional information on conduction\ud slowing and denervation to assist in monitoring the onset of re‑innervation. High‑resolution nerve\ud imaging complements neurophysiological data and allows direct visualization of the nerve injury\ud while providing insight into its cause and facilitating surgical treatment planning. Indications and\ud limits of each instrumental examination are discussed

“…A medium number of directions of interrogation [11][12][13][14][15][16][17][18][19] is usually sufficient to obtain good tractography while preserving enough SNR. Keeping zero interslice spacing allows multiplanar reformats to be obtained along the nerve axis without stairstep artifacts.…”

“…Keeping zero interslice spacing allows multiplanar reformats to be obtained along the nerve axis without stairstep artifacts. Diffusion-weighted imaging (DWI) allows quantitative nerve imaging, and diffusion tensor imaging (DTI) further allows tractography to provide evaluation of internal nerve and intralesional architecture [12][13][14][15] (►Fig. 5).…”

MR neurography (MRN) techniques continue to evolve, leading to a better demonstration of peripheral nerve anatomy and pathology. This article discusses various technical perspectives and provides recommendations to obtain the best possible high-resolution imaging of the peripheral nerves in various areas of the body. We also discuss technical perspectives of whole-body MRN and its potential utility.

Invasive arteriography and angiography are for detecting complications of ATOS such as thrombosis, embolisation, and aneurysm.…”
