The multi\u2010echo acquisition enabled distortion correction using reverse phase\u2010encoding between echoes. Motion and distortion correction were applied before fitting a joint T2\u2010IVIM model across the b\u2010value and TE dimensions to obtain TE\u2010independent IVIM parameters and compartment\u2010specific T2 estimates. For comparison, a previously established single\u2010echo T2\u2010IVIM protocol with longer scan times and a single\u2010echo protocol matched to the multi\u2010echo parameters were acquired. Uncertainty was evaluated with wild bootstrap error analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The multi\u2010echo approach enabled motion\u2010 and distortion\u2010corrected T2\u2010IVIM mapping in under 5\u2009min, compared with 11\u201313\u2009min for the prior minimal single\u2010echo protocol or nearly 19\u2009min when acquired as separate shots. The liver was selected as the target organ due to its marked sensitivity to  effects in standard IVIM. Error analysis showed comparable per\u2010voxel uncertainty between the multi\u2010echo method and the minimal single\u2010echo protocol.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The combination of multi\u2010echo sequence design and artifact correction enabled stable fitting of the extended T2\u2010IVIM model with improved liver coverage and less than half the scan time of prior protocols.
