After six months, water tolerance improved significantly. Compared to early dynamic MRI, late MRI gastric motility patterns revealed an improvement trend in the form of a significant decrease in antral frequency and an increase in antral velocity, sleeve transit, and contraction height for both water and juice (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

Water tolerance improves significantly 6 months after LSG but remains worse than juice tolerance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s11695-025-08276-8","type":"journal-article","created":{"date-parts":[[2025,10,12]],"date-time":"2025-10-12T05:18:16Z","timestamp":1760246296000},"page":"4678-4685","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unraveling the Enigma of Post-sleeve Differential Liquid Tolerance: A Time-Resolved MRI Study"],"prefix":"10.1007","volume":"35","author":[{"given":"Athar","family":"Elward","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad","family":"Omar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Abdelsalam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Islam","family":"Shawali","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mina","family":"Makram","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Refaat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,10,12]]},"reference":[{"issue":"Suppl 1(Suppl 1","key":"8276_CR1","doi-asserted-by":"publisher","first-page":"79","DOI":"10.1590\/S0102-6720201500S100021","volume":"28","author":"MA Stumpf","year":"2015","unstructured":"Stumpf MA, Rodrigues MR, Kluthcovsky AC, et al.
