An ultra-flexible AIR 64-Channel bilateral phased array coil is described for acquiring high-sensitivity images of the brachial plexus by wrapping coil elements snugly around the cervical, shoulder, axillary, and arm regions. This coil comprises a foam posterior and flexible flaps with a low loss malleable conductor optimized for zero reactance. An exceptionally low noise preamplifier is tolerant of a wide range of loading. This coil facilitates imaging large fields of view bilateral brachial plexi, as well as higher resolution unilateral imaging for detailed evaluation of nerve fascicular architecture and other pathology, thereby optimizing setup time and patient comfort.
