Image-Guided Volume-Selective Magnetic Resonance Spectroscopy and Relaxometry: Application to the Porcine Kidney Perfused with Perfluorocarbons
Image contrast in magnetic resonance (MR) tomography is governed largely by the relaxation times Tl and T2 of the tissue. In imaging procedures, relaxation enters in an indirect way. On the basis of volume-selective signals one has the possibility to measure precisely parameters which are suitable for the characterization of tissue. We have therefore developed pulse sequences for the localized and spectroscopically resolved determination of precise relaxation times.
