Fat to water levels and their transverse relaxation (T2)
times measured with magnetic resonance in spinal bone
marrow have been relevant to the study of a number of
diseases. Previous measurements characterizing fat to
water ratios and T2 values have been limited to the
lumbar region of the spine. In this work, fat to water
ratios and fat and water T2 values are determined for
the L3 and T7 vertebrae of 20 healthy volunteers;
measurements were also obtained from the C4 vertebra in
19 of the volunteers. Measurements were performed with a
Point RESolved Spectroscopy (PRESS) sequence at 3 T.
