Simultaneous measurements of R2 and R2’ using the Gradient Echo Sampling of a Spin Echo (GESSE) sequence were made at multiple spin echo times in four volunteers. Secondary measurements of R2 and R2* were made using classical Spin Echo and Gradient Echo approaches. The variation in measured relaxation rates are explored and show a general overestimation of transverse relaxation in white and grey matter when measured with GESSE suggesting a lack of complexity in the model used to describe the GESSE signal.
