Figure 2

OPG (orthopantomogram) MRI reconstructions (MR-OPG) from a 3D double-echo steady-state (DESS) dataset. T2-w imaging using DESS-MRI (scan time approximately 12 minutes) allows visualization of the complex neural microarchitecture of the thinnest peripheral branches of the mandibular division of the trigeminal nerve. (a) MR-OPG with a slice thickness of 0.5 mm were created using the curved multiplanar reconstruction (MPR) function of syngo.via (release VB60a, Siemens Healthineers, Erlangen, Germany). (b) Overview image of a DESS MR-OPG. (c) Visualization of the fourth quadrant of a study participant’s DESS MR-OPG. The long arrow points to the inferior alveolar nerve (IAN), while the short arrow represents the lingual nerve. (d) Visualization of the course of the T2- weighted hyperintense signal of the IAN through the mandible, whereas (e) shows a retromolar branch of the IAN.
