The purpose of the study is to develop new techniques for functional brain imaging (commonly referred to as functional MRI, or fMRI), utilizing the unique imaging capabilities of the General Electric (GE) Signa Cardiovascular Magnetic Resonance (CVMR) System. GE has received FDA clearance of 510(k) submissions for the use of this system on humans. The system is indicated for use as a diagnostic MRI system (device) that produces transverse, sagittal, coronal, and oblique cross-sectional images that display the internal structure and function of the head and body. At UC Davis Medical Center, we have installed a GE Signa CVMR System, with hardware and software optimized for cardiac and neurological imaging applications. This system is located in Rooms 1231 and 1232, UC Davis Imaging Center, 4701 X Street, Sacramento, CA 95817. The CVMR System is designed to provide imaging with temporal resolution of short as 28 ms, and improved signal to noise relative to standard systems. It will allow UCDMC researchers to engage in fMRI research that elucidates brain function.
