Cardiac function was evaluated in mdx and control mice (C57BL\/6JJmsSlc mice) at 8 and 12 weeks of age. Preclinical 7-T MRI was used to capture short-axis, longitudinal two-chamber view and longitudinal four-chamber view cine images of mdx and control mice. Strain values were measured and evaluated from cine images acquired using the feature tracking method. The left ventricular ejection fraction was significantly less (p &lt; 0.01 each) in the mdx group at both 8 (control, 56.6 \u00b1 2.3% mdx, 47.2 \u00b1 7.4%) and 12 weeks (control, 53.9 \u00b1 3.3% mdx, 44.1 \u00b1 2.7%). In the strain analysis, all strain value peaks were significantly less in mdx mice, except for the longitudinal strain of the four-chamber view at both 8 and 12 weeks of age. Strain analysis with feature tracking and self-gated magnetic resonance cine imaging is useful for assessing cardiac function in young mdx mice.<\/jats:p>","DOI":"10.3390\/diagnostics13081472","type":"journal-article","created":{"date-parts":[[2023,4,20]],"date-time":"2023-04-20T01:42:39Z","timestamp":1681954959000},"page":"1472","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Evaluation of Cardiac Function in Young Mdx Mice Using MRI with Feature Tracking and Self-Gated Magnetic Resonance Cine Imaging"],"prefix":"10.3390","volume":"13","author":[{"given":"Junpei","family":"Ueda","sequence":"first","affiliation":[{"name":"Department of Medical Physics and Engineering, Division of Health Sciences, Osaka University Graduate School of Medicine, Suita 560-0871, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5100-9561","authenticated-orcid":false,"given":"Shigeyoshi","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Medical Physics and Engineering, Division of Health Sciences, Osaka University Graduate School of Medicine, Suita 560-0871, Osaka, Japan"},{"name":"Department of Advanced Medical Technologies, National Cardiovascular and Cerebral Research Center, Suita 564-8565, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jelinkova, S., Sleiman, Y., Fojt\u00edk, P., Aimond, F., Finan, A., Hugon, G., Scheuermann, V., Beckerov\u00e1, D., Cazorla, O., and Vincenti, M.
