Protocols included Proton density\u2013weighted sequence with fat suppression (PD-FS) (coronal\/sagittal\/axial), T1 (coronal or sagittal), and T2 (axial) optimized for time in sMRI and for image quality in DL-MRI. Three blinded readers with different levels of experience rated overall image quality, anatomical delineation, fat saturation, motion artefacts, and foreign-body artefacts on 5-point Likert scales. Quantitative analysis was performed to calculate SNR, CNR, and generalised metrics (gSNR, gCNR). Group differences were assessed using two-sided Welch\u2019s t-tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Readers rated DL higher in nearly all categories and sequences, with mean gains of ~\u20090.48\u20130.70 for overall image quality and ~\u20090.38\u20130.54 for anatomical delineation (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009\u2264\u20090.001). Fat saturation improved for PD-FS coronal and axial, motion artefacts improved for PD-FS coronal and sagittal (and slightly for axial), and foreign-body artefacts were comparable. Quantitatively, PD-FS showed higher muscle SNR and higher gSNR\/gCNR with DL (bone SNR non-significant); T2 showed higher bone SNR and higher CNR\/gCNR but lower muscle SNR\/gSNR; and T1 showed lower SNR\/gSNR with preserved CNR. Compared with sMRI, DL-MRI achieved a twofold improvement in in-plane resolution (0.4\u2009\u00d7\u20090.4\u00a0mm\u00b2 vs. 0.2\u2009\u00d7\u20090.2\u00a0mm\u00b2) and reduced slice thickness (3.0\u00a0mm vs. 2.5\u00a0mm. and down to 1.0\u00a0mm for T2-weighted sequences), while slightly shortening total scan time (10:14\u00a0min vs. 9:30\u00a0min).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>DL-MRI provided superior image quality and higher resolution over time-optimized standard knee MRI at 3 Tesla.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial registration<\/jats:title>\n                    <jats:p>Not applicable.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12880-026-02251-0","type":"journal-article","created":{"date-parts":[[2026,3,3]],"date-time":"2026-03-03T17:03:21Z","timestamp":1772557401000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimizing high-resolution knee MRI at 3 tesla: conventional acceleration versus deep learning reconstruction"],"prefix":"10.1186","volume":"26","author":[{"given":"Dominik","family":"Deppe","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus Herbert","family":"Lerchbaumer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid M.","family":"Baghdadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hassan Ali","family":"Alyousef","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leila Vivien","family":"Nitschke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Kohnert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominik","family":"Geisel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Pohlmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moritz","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thula","family":"Walter-Rittel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,3,3]]},"reference":[{"key":"2251_CR1","doi-asserted-by":"publisher","first-page":"3055","DOI":"10.1002\/mrm.26977","volume":"79","author":"K Hammernik","year":"2018","unstructured":"Hammernik K, Klatzer T, Kobler E, et al.
