Comparison
of 2D and 3D simultaneously acquired T1, T2 and PD maps on 3T scanners of
different vendors shows almost-general agreement between scanners, sequence and
with and without GRAPPA, SENSE, or compressed sensing. T1 and T2 values
approach the reference values and are reproducible.
Figure 3: Measured
versus reference T1 (left) and T2 (right). Colour of the symbols indicates vendor, the shape
indicates acceleration used, and filled vs hollow indicates 2D vs 3D respectively.
Figure 4: Difference
between measured and reference T1 (left) and T2 (right) values. Colour of the
symbols indicates vendor, the shape indicates acceleration used, and filled vs
hollow indicates 2D vs 3D respectively.
