Abstract

An attempt was made to use 31P magnetic resonance spectroscopic imaging (MRSI) for evaluation of human brain disease. An improved RF coil was constructed, a protocol was developed using a 3-D spin-echo phase-encoding method, and patients and normal volunteers were studied. The RF coil provided homogeneous B1 over a large volume and improved sensitivity. The results demonstrate the marked advantage of 31P-MRSI over single-volume 31P-mRS techniques and the clinical value of 31P-MRSI for evaluation of patients with brain disease. Information was derived from regions of brain outside of the primary diseased volume and decreased metabolite concentrations were detected in regions previously though to be uninvolved by disease. The ability to sum over voxels facilitated quantitation over irregular, anatomically significant volumes.
