Phantom experiments compared Cartesian sampling (reference) with stack\u2010of\u2010stars and diamond radial sampling. Volunteer scans utilized stack\u2010of\u2010stars and diamond sampling. T1\u03c1 values were calculated using mono\u2010exponential fitting with MAPSS (five or three TSL pairs) and fast\u2010MAPSS (three TSLs). These values were compared across sampling methods and T1\u03c1 techniques in phantom and in vivo for the liver, pancreas, and muscles.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Diamond sampling achieved a 2.2\u2010fold acceleration compared to stack\u2010of\u2010stars. In phantom experiments, mean T1\u03c1 differences from reference Cartesian MAPSS were \u22121.93% for stack\u2010of\u2010stars, and \u22120.09% for diamond sampling. Fast\u2010MAPSS with three TSLs resulted in differences of 0.54% (stack\u2010of\u2010stars) and 1.45% (diamond).

Bland\u2013Altman analysis revealed minimal biases (&lt;1.5\u2009ms) between the methods.
