Fig 4. Measured signal intensities (SIs) as a function of TE for TR = 8000 ms and a dilution factor of 1:2048. At 1.5T (A) and 3T (B), measured signal intensities are closely plotted at shorter TE values. With longer TE and greater T2-weighting, T2(*) effects of contrast predominate, and there is a decrease in measured signal intensity. The greatest signal intensity loss per TE is demonstrated for gadobenate.
