Examples of MRI Nerve Imaging.

a: Tractography of the median nerve in carpal tunnel syndrome, where patients displayed a significant decrease in median nerve fractional anisotropy. Taken from Figure 2 (Tractography image demonstrating the median nerve, coded in blue, with an excellent correlation, with the reference T1-weighted image in a patient suffering from carpal tunnel syndrome) of Khalil et al.⁴⁴ with kind permission from Springer Science and Business Media.

b: Three-dimensional diffusion-weighted reversed fast imaging with steady-state precession (3D DWPSIF) of enlarged plantar nerves in a patient with entrapments following a repeat tarsal tunnel surgery. Taken from Figure 5b (A 32-year-old female with medial and lateral plantar nerve entrapments following a repeat tarsal tunnel surgery … Notice the depiction of the enlarged plantar nerves on the 3D DW-PSIF image) of Chhabra et al.⁴² with kind permission from Springer Science and Business Media.

c: Lumbar nerve roots in a healthy subject and a patient with right L1-S1 foraminal stenosis, indicative of nerve root entrapment. Taken from Eguchi et al.⁴³ with permission of the American Society of Neuroradiology.

d: Fiber tracking reconstruction in a healthy woman and a patient with widespread endometriosis. Taken from Figures 2 and 3 (2: Example of fibre tracking reconstruction in a healthy woman showing S1, S2 and S3 nerve roots. Images are displayed in the coronal planes (radiological convention). Fibre bundles S1 to S3 display a homogeneous appearance and regular course bilaterally. 3: Fibre tracking reconstruction in a woman affected by endometriosis of the medium and posterior compartment. The fibre bundles are short, stubby and have lots of branches.) of Manganaro et al.⁴⁵ with kind permission from Springer Science and Business Media.
