Measurement of the transversal relaxation time T2 is one of the most established techniques to characterize material samples or biological tissue by means of NMR. If molecular motion is restricted, direct spin-spin interactions become relevant and extremely short T2 values are expected. Here we present a slice-selective MRI method for mapping of submillisecond T2. The method utilizes a spin echo preparation followed by slice-selective ultra-short echo time imaging. Mapping of submillisecond T2 could be useful in studies on material samples, short T2 biological tissue like bone, tendon or cartilage and on quadrupolar nuclei like 23Na, 35Cl, and 17O.
