A series of 5 measurements using 5-mm-diameter regions of interest\nwere performed, with the results expressed in m\/s and kPa. Exam feasibility was assessed using the IQR\/\nMedian ratio as \u226430% for kPa, and \u226415% for m\/s. Descriptive statistics, Shapiro-Wilk W, Levene's, MannWhitney U tests and Spearman correlation analysis were used for statistical assessment. Results: The feasibility of the exam was 68.97% for the right liver lobe, 67.24% for the left lobe, 91.07% for the spleen, 89.29%\nfor the right kidney, 85.71% for the left kidney. Mean results: right liver lobe: 1.43 m\/s, SD \u00b10.11, 6.04 kPa,\nSD \u00b10.97, left liver lobe: 1.41 m\/s, SD \u00b10.12, 5.86 kPa, SD \u00b11.02, spleen: 2.36 m\/s, SD \u00b10.21, 16.99 kPa,\nSD \u00b13.21, right kidney: 1.92 m\/s, SD \u00b10.18, 11.34 kPa, SD \u00b13.21, left kidney: 1.88 m\/s, SD \u00b10.16, 10.81 kPa,\nSD \u00b11.80. The splenic-hepatic elastography index for m\/s and kPa results was as follows: mean 1.65, SD\n\u00b10.20, mean 2.82, SD \u00b10.73, respectively. No differences were found between the right vs left lobe of\nthe liver, or the right vs left kidney; there was no correlation between the measurements and gender or\nfood intake interval &gt;60 minutes. A positive correlation was found between the results for the right and\nleft lobe of the liver and age, and the results for the left lobe of the liver and body weight. Conclusions:\nTwo-dimensional shear wave elastography of the liver, spleen and kidneys can be successfully performed\nin healthy neonates. We obtained reliable mean shear wave elastography values for the examined organs.<\/jats:p>","DOI":"10.15557\/jou.2025.0010","type":"journal-article","created":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T07:35:01Z","timestamp":1744788901000},"source":"Crossref","is-referenced-by-count":4,"title":["Two-dimensional shear wave elastography for assessing liver, spleen, and kidneys in healthy newborns"],"prefix":"10.15557","volume":"25","author":[{"name":"Department of Intensive Care and Neonatal Pathology, The Ludwik Rydygier Provincial Polyclinical Hospital in Toru\u0144, Poland","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7689-3103","authenticated-orcid":false,"given":"Grzegorz","family":"Postek","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8453-7785","authenticated-orcid":false,"given":"Pawe\u0142","family":"Zalewski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Exercise Physiology and Functional Anatomy, Faculty of Health Sciences Medical College in Bydgoszcz, The Nicolaus Copernicus University in Toru\u0144, Poland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8790-5176","authenticated-orcid":false,"given":"Iwona","family":"Sadowska-Krawczenko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Neonatal Intensive Care Unit, Dr Jan Biziel University Hospital in Bydgoszcz, Department of Neonatology, Medical College in Bydgoszcz, The Nicolaus Copernicus University in Toru\u0144, Poland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6250","published-online":{"date-parts":[[2025,4,7]]},"container-title":["Journal Of Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/jultrason.pl\/assets\/pdf\/artykuly\/10-jou-00052-2024-postek-eng-pdf.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T07:35:03Z","timestamp":1744788903000},"score":1,"resource":{"primary":{"URL":"https:\/\/jultrason.pl\/index.php\/issues\/volume-25-no-100\/two-dimensional-shear-wave-elastography-for-assessing-liver-spleen-and-kidneys-in-healthy-newborns"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,4]]},"references-count":0,"journal-issue":{"issue":"100","published-online":{"date-parts":[[2025,4,7]]},"published-print":{"date-parts":[[2025,4,4]]}},"URL":"https:\/\/doi.org\/10.15557\/jou.2025.0010","relation":{},"ISSN":["2084-8404","2451-070X"],"issn-type":[{"value":"2084-8404","type":"print"},{"value":"2451-070X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,4]]}}}
