Diagnostic value of spinal US: comparative study with MR imaging in pediatric patients.

abstract：:The authors designed and built an overlapping surface coil assembly for magnetic resonance imaging of the spine. A small and a large coil are included, and use of one can be switched to the other without need for patient repositioning. The images are not degraded, and screening studies can immediately be followed by d...
