In order to set up magnetic resonance imaging (MRI) procedures of arbitrary voxel dimensions, slice orientation, and sequence timing in a reasonable time, some form of automatic gradient pulse calibration is required. One such method, involving simul

An ischemic clamp model of exercise was used to evaluate the potential role of blood flow in mediating changes in the magnetic resonance imaging appearance of skeletal muscle. Proton relaxation times of muscle were serially estimated in 10 healthy su

Therapeutic success could be enhanced if therapy were tailored to the characteristics of specific tumors. We have been developing novel approaches to measuring tumor oxygen tension in vivo, and recently reported a method based on 19F nuclear magnetic

We demonstrate a novel approach to measuring regional tumor oxygen tension using 19F pulse burst saturation recovery echo planar imaging (EPI) relaxometry of hexafluorobenzene. Hexafluorobenzene offers exceptional sensitivity to changes in oxygen ten

The authors used fluorine-19 inversion-recovery (IR) echo-planar imaging (EPI) to map oxygen tension on the basis of the spin-lattice relaxation rate (R1) of sequestered perfluorocarbon. R1 measured with IR-EPI varied as a linear function of oxygen t

Emulsions of perfluorotributylamine (FTBA) and perflubron were evaluated for their utility in 19F echo planar imaging. Fluorine images of the emulsions were obtained in a phantom and two mice that had been predosed. Both agents, but particularly perf

Proton NMR spectroscopy (spatially resolved) at 0.7 Tesla with a whole body superconducting magnet was performed on bone marrow from human lumbar spine to measure the lipid/water ratio. Phase-encoded proton spectroscopy was performed by using (1) a s
