The application of contrast-enhanced ultrasound (CEUS) in bladder cancer requires further validation. Methods: Using histopathology as the reference standard, we compared the diagnostic performance of CEUS and enhanced magnetic resonance imaging (E-MRI) in 190 patients who underwent transurethral resection of bladder tumor. The accuracy, sensitivity, and specificity of both modalities in determining malignancy and muscular invasion were analyzed. Results: For diagnosing malignant tumors, the accuracy of CEUS and E-MRI was 83.87% and 80.64%, respectively. No significant differences were observed in sensitivity (85.71% vs. 84.28%) or specificity (78.26% vs. 69.56%) (p &gt; 0.05). In assessing muscular invasion, CEUS demonstrated significantly higher specificity than E-MRI (95% vs. 77.5%, p = 0.039), while no significant difference was found in sensitivity (77.33% vs. 74.66%). Conclusion: CEUS exhibits superior specificity for evaluating muscular invasion in bladder urothelial carcinoma and can serve as a valuable complement to E-MRI for clinical staging.<\/jats:p>","DOI":"10.1159\/000550940","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T17:01:50Z","timestamp":1773075710000},"page":"1-7","source":"Crossref","is-referenced-by-count":0,"title":["Comparison of Contrast-Enhanced Ultrasound and Enhanced Magnetic Resonance Imaging in Assessing the Depth of Invasion in Bladder Urothelial Carcinoma"],"prefix":"10.1159","author":[{"given":"Yongqi","family":"Dou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiawei","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongjiang","family":"Xiong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2026,3,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.233020"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3390\/medicina57080749"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2511080873"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2005.07.062"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1080\/02841850410005390"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-018-1516-1"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3389\/fonc.2020.00972"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.3390\/life14070857"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinimag.2010.11.001"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.14.14203"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.3390\/cancers13215469"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2021.04.032"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1515\/raon-2015-0042"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1093\/ecco-jcc\/jjae034"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.3348\/kjr.2018.0273"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v29.i25.4021"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1259\/bjr\/43400531"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000024625"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.232815"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.09.2741"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v17.i1.42"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000550940","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T16:01:59Z","timestamp":1777392119000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000550940"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,9]]},"references-count":21,"URL":"https:\/\/doi.org\/10.1159\/000550940","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,9]]}}}
