The scans were evaluated by a blinded radiologist for abdominal muscle thickness, subcutaneous fat changes, and abdominal separation. The results were compared with the MRI\/CT-assisted measurements taken at baseline and 6-week follow-up. Correlations between collected data sets were calculated and tested. The incidence of any adverse events related to earlier treatments was monitored.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>When comparing the 1-year follow-up measurements with the baseline, the MRI\/CT-assisted calculations revealed mean reductions of 14.63% (2.97\u2005[2.11] mm) in fat, 19.05% (1.89\u2005[0.88] mm) in muscle thickening, and 10.46% (1.96\u2005[1.71] mm) in diastasis recti. All changes were significant (P\u2005&amp;lt;\u20050.05) and not related to weight fluctuations (P\u2005&amp;gt;\u20050.05). The baseline width of diastasis positively correlated with the degree of improvement at follow-up. No adverse events were reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The HIFEM-induced muscle hypertrophy, fat reduction, and reduction in abdominal separation were maintained 1-year posttreatment.
