  • Abstract
    Low-field MRI is a less expensive and more flexible alternative to high-field proton MRI. T1 measurements of hyperpolarized 129Xe (H-Xe) were made at 85 Gauss using a 100 kHz homemade spectrometer in the fringe field of a 1.89 Tesla superconducting magnet. T1 was measured in the range of 400-800s with a SNR of 11±1. These T1 values indicate that a low-field MR imaging system may be feasible
