Brachial plexus: MR imaging with a dedicated phased array of surface coils

Radiology. 1997 Apr;203(1):286-9. doi: 10.1148/radiology.203.1.9122409.


A phased array of surface coils was constructed for magnetic resonance imaging in three different regions in the brachial plexus. Four-coil subsets of the six-coil array were activated at any given time during imaging in three volunteers. An in vivo estimate of the signal-to-noise ratio (S/N) at three locations in the brachial plexus indicated that the phased-array coil provided a signal-to-noise ratio that was three to six times higher than that of the body coil.
