After standard clinical imaging, selected sequences were repeated following coil exchange. Five pediatric radiologists independently evaluated paired image sets for subjective signal-to-noise ratio (SNR) and coil-related artifacts. Objective image quality was assessed using organ- and tissue-based SNR estimates and contrast-to-noise ratio (CNR) measurements. Patients and MRI technologists completed questionnaires regarding comfort, usability, and examination experience.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All 20 patients (median age, 15\u00a0years; 55% female) underwent imaging with both coils. Radiologists rated the novel coil as similar to the conventional coil for subjective SNR across all three sequences under study; coil-related artifacts were uncommon (2% of assessments for all sequences evaluated). Objective analysis showed no significant image-based SNR differences for most sequences, although the flexible coil demonstrated higher liver SNR on axial diffusion-weighted imaging (adjusted\n                      <jats:italic>P<\/jats:italic>\n                      =0.01). CNR did not differ between coils. Patients reported greater comfort and less anxiety with the flexible coil; 55% preferred it for future MRI examinations versus 20% for the conventional coil. Technologists also favored the flexible coil, with 70% expressing an overall preference.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The flexible blanket-like torso coil provided image quality similar to a conventional coil and was generally preferred by patients and MRI technologists.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00247-026-06761-5","type":"journal-article","created":{"date-parts":[[2026,8,22]],"date-time":"2026-08-22T09:17:10Z","timestamp":1787390230000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of a novel flexible, lightweight blanket-like torso coil in pediatric MRI at 1.5-T \u2013 initial experience"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0124-0164","authenticated-orcid":false,"given":"Jonathan R.","family":"Dillman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean A.","family":"Tkach","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
