Subtraction of unidirectionally encoded images for suppression of heavily isotropic objects (SUSHI) for selective visualization of peripheral nerves.

ABSTRACT:

Introduction

The aim of this study was to introduce and assess a new magnetic resonance (MR) technique for selective peripheral nerve imaging, called "subtraction of unidirectionally encoded images for suppression of heavily isotropic objects" (SUSHI).

Methods

Six volunteers underwent diffusion-weighted MR neurography (DW-MRN) of the brachial plexus, and seven volunteers underwent DW-MRN of the sciatic, common peroneal, and tibial nerves at the level of the knee, at 1.5 T. DW-MRN images with SUSHI (DW-MRN(SUSHI)) and conventional DW-MRN images (DW-MRN(AP)) were displayed using a coronal maximum intensity projection and evaluated by two independent observers regarding signal suppression of lymph nodes, bone marrow, veins, and articular fluids and regarding signal intensity of
