T2* maps were obtained for Xe129 in the healthy human lung at 1.5T and 3T. The mean T2* values were 50.4 and 27.4 ms at 1.5T and 3T, respectively. The mean T2* value for Xe129 at 3T was essentially the same as that reported for He3 at 1.5T. The longer T2* for Xe129 at a given field strength will permit the data sampling periods (receiver bandwidths) used for Xe129 to be longer (lower) than those suitable for He3.
