A slice-selective CPMG pulse sequence with a DANTE-Z selective scheme for measuring spatially-resolved Tdistributions.

Spatially resolved magnetic resonance spin-spin relaxation distribution measurement methods

A method of measuring a parameter in a sample by imaging at least a portion of the sample using a spin-echo single-point imaging (SE-SPI) pulse sequence. This method involves applying a pure phase encoding to the SE-SPI pulse sequence, acquiring a multiplicity of echoes, and determining the spatially resolved Tdistribution. In another embodiment, individual echoes are separately phase encoded in a multi-echo acquisition and the SE-SPI pulse sequence is a hybrid SE-SPI sequence. In another embodiment, an external force can be used to build up a distribution of saturations in the sample, and a Tdistribution can be measured for the sample, which is then used to determine a parameter of the sample. A spatially resolved Tdistribution can also be measured and a resulting spatially resolved Tdistribution used to determine the Tdistribution as a function of capillary pressure.
