โฆ Synopsis
A liquid nitrogen (LN2) cooled dual-channel array coil was designed and built for use on a 3.0-T whole-body scanner. In vivo imaging of a volunteer's fingers and imaging of a deceased mouse and oil phantom were performed using the LN2 cooled array and a similar room-temperature coil. Imaging results showed that the LN2 cooled array provides a signal-to-noise ratio gain of up to 240% as compared with its room-temperature counterpart. LN2 cooled arrays may be useful for high-resolution clinical imaging of joints, skin, eyes and peripheral vessels as well as for biomedical imaging of small animals in human disease modeling.

Rationale and Objective: Conventional MRI techniques to track ferumoxide-labeled stem cells rely on the detection of signal voids, which often mimic other image artifacts. Several bright marker imaging techniques have been proposed (1,2), but are either poorly suited for in vivo cardiac imaging or h
