“…Because the DTI protocols are being standardized and initial reliability studies are being performed, it is likely to play an important role in peripheral nerve imaging, including the brachial plexus. 15,16 MRN imaging anatomy of the thoracic outlet can be subdivided into 3 anatomic spaces, from medial to lateral: the interscalene triangle, the costoclavicular space, and the retropectoralis minor space (also called the subcoracoid tunnel). These are best characterized on sagittal and coronal images.…”

SUMMARY:With advancement in 3D imaging, better fat-suppression techniques, and superior coil designs for MR imaging and the increasing availability and use of 3T magnets, the visualization of the complexity of the brachial plexus has become facile. The relevant imaging findings are described for normal and pathologic conditions of the brachial plexus. These radiologic findings are supported by clinical and/or EMG/surgical data, and corresponding high-resolution MR neurography images are illustrated. Because the brachial plexus can be affected by a plethora of pathologies, resulting in often serious and disabling complications, a better radiologic insight has great potential in aiding physicians in rendering superior services to patients.

“…7,[10][11][12] Some studies have highlighted its high reproducibility and feasibility in the clinical setting. 13,14 For example, reproducibility studies in brachial plexus show an overall reproducibility between 81% and 92%, considering combined influence of the observer and of the repeated measurements.…”

Objective: To evaluate the usefulness of diffusion tensor imaging (DTI) in the clinical setting as a complementary tool to conventional MRI in the study and assessment of the sciatic nerve and its pathologies. Methods: 17 patients diagnosed with different types of sciatic neuropathy and 10 healthy controls underwent a conventional MRI and a DTI study in a 3-T MR scanner (Achieva® 3-T X-Series; Philips Healthcare, Netherlands). Results: In the control group, we were able to track and visualize the common sciatic nerve and its main branches from hip to foot. In the patient group, the affected sciatic nerves presented statistically significant lower fractional anisotropy values and higher apparent diffusion coefficient values when compared with controls, suggesting nerve damage. In all cases, DTI offered complementary information for diagnosis and/or confirmation of the suspected pathology. When compared with conventional MRI, DTI showed higher sensitivity for nerve damage detection. Conclusion: DTI offers a significant improvement and an important complement to visualize the sciatic nerve and its main branches. In patients with sciatic nerve pathology DTI allows to a better detection and characterization of the nerve damage. Advances in knowledge: DTI enables in vivo dissection of the sciatic nerve white matter fibres; its use offers a significant improvement and complement to conventional MRI.

“…Patients with presumptive nTOS often have antecedent history of accidental injury, and may present within the workers' compensation or disability system. The associated disability may cloud the accuracy of the diagnosis and compensation status correlates with poor outcomes after surgical intervention [45]. It behooves the surgeon to consider that, while in general well-tolerated, operative treatment of nTOS is associated with several risks including injury to the subclavian artery or vein, brachial plexus, or phrenic nerve.…”

Brachial plexus MR imaging: accuracy and reproducibility of DTI-derived measurements and fibre tractography at 3.0-T

Abstract: DTI of brachial plexus nerves is reliable. The healthy contralateral side can be used as an internal control considering that changes in FA and ADC values of less that 37% and 32% will not be clinically detectable with confidence.
