Measured time constant associated with
spin-spin relaxation for loss of magnetization in the
\(xy\) plane.
Note: \(T_{2}^{*}\) includes losses due to
\(\boldsymbol{B_{0}}\) inhomogeneity as well as spin-spin relaxation and is always less than or equal to the
spin-lattice relaxation time (
\(T_{2}\)).
