Visualization of the extracranial branches of the trigeminal nerve using iMSDE preparation 3D IR-TSE

Visualization of the anatomy of extracranial the trigeminal nerve (TGN) is crucial to detect nerve pathological alterations and differentiate pathologic causes. As a novel and safe nerve imaging technique in magnetic resonance neurography (MRN), the iMSDE pulse could result in uniform vascular signal suppression without additional contrast agents, which has been demonstrated to improve the visualization of peripheral nerves in several anatomical regions. Our results suggested that the iMSDE 3DIRTSE is a viable alternative to conventional 3DIRTSE and contrast-enhanced 3DIRTSE for MRN of the extracranial branches of TGN in clinical practice.
