MRI of brachial plexus using diffusion tensor imaging: a pilot study for the use of resolve sequence surgical and radiologic anatomy.
Background: Clinical exam is the goldstandard for surgical indication. ENMG and conventional MRI are insufficient to understand the highly variable clinical presentation of brachial plexus (BP) lesions. DTI is based on motion of water molecules and can explore nerve function. Purpose: This pilot stu...

ENMG and conventional MRI are insufficient to understand the highly variable clinical presentation of brachial plexus (BP) lesions. DTI is based on motion of water molecules and can explore nerve function. Purpose: This pilot study of healthy subjects aimed to develop RESOLVE sequence for BP exploration using diffusion MRI. The main objective was to provide complete precise information from DTI cartography associated with anatomical data. Methods: Six healthy volunteers were scanned using 3T PRISMA scanner with anatomic 3D STIR SPACE and RESOLVE diffusion sequences. Diffusion parametric maps of fractional anisotropy (FA) were extracted from RESOLVE acquisitions. A reproducible method for roots volumes and angles measurements was created using 3DSlicer. ROI were segmented on Mean B0 sequences. FA measurements were obtained with ROI on Mean B0 sequences. Results: RESOLVE sequence was adapted to the BP. Mean FA was 0.30. Angles measurements on 3D STIR SPACE sequences showed increasing values from proximal to distal roots with an 0.6 ICC. Volume measurements on anatomic sequences varied widely from one root to another but did not show any significant difference on laterality. Conclusions: A new and reproducible method for BP exploration was developed, using MRI RESOLVE DTI sequences. Complete mapping was obtained but a low resolution of track density imaging did not allow to exploit distal nerves. Deterministic tractography principal limit was the lack of resolution. Extraction of diffusion, volumetric and angular parameters of the plexus roots, and scripts creation for image processing was adapted to the healthy BP. pubtype: Academic Journal doctype: Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
