However, its usefulness in differentiating various benign parotid tumors has not been determined so far. This study aimed to systematically review the literature to determine the utility of CEUS in the preoperative differentiation between pleomorphic adenomas (PAs) and Warthin\u2019s tumors (WTs) of the parotid gland. PubMed, Embase, and Cochrane were searched for English-language articles published until 21 July 2022. Fifteen studies were included. On CEUS examination, a significantly greater percentage of PAs displayed heterogeneous enhancement texture compared to WTs. Contrarily, the enhanced lesion size, the enhancement margin, and the presence of the enhancement rim did not differ significantly between the entities. Significantly longer normalized mean transit time (nMTT) and time to peak (TTP) were observed in PAs. Contrarily, the mean values of area under the curve (AUC) and time from peak to one half (TPH) were significantly higher for WTs. Due to the considerable overlap among the qualitative CEUS characteristics of PAs and WTs, the reproducible, investigator-independent quantitative CEUS measurements have a greater potential to distinguish PAs from WTs, which might influence the selection of an appropriate management strategy.<\/jats:p>","DOI":"10.3390\/jcm11247360","type":"journal-article","created":{"date-parts":[[2022,12,12]],"date-time":"2022-12-12T04:34:20Z","timestamp":1670819660000},"page":"7360","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Contrast-Enhanced Ultrasound in the Differentiation between the Most Common Benign Parotid Gland Tumors: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5848-9564","authenticated-orcid":false,"given":"Marta","family":"Rogalska","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0145-4680","authenticated-orcid":false,"given":"Lukasz","family":"Antkowiak","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurosurgery, Medical University of Silesia in Katowice, 40-752 Katowice, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5919-5346","authenticated-orcid":false,"given":"Anna","family":"Kasperczuk","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Institute of Biomedical Engineering, Bialystok University of Technology, 15-351 Bialystok, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3242-8047","authenticated-orcid":false,"given":"Wojciech","family":"Scierski","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology and Oncological Laryngology, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 41-800 Zabrze, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1763","DOI":"10.1007\/s00405-020-05868-1","article-title":"The Role of Fine-Needle Aspiration Biopsy (FNAB) in the Diagnostic Management of Parotid Gland Masses with Emphasis on Potential Pitfalls","volume":"277","author":"Dostalova","year":"2020","journal-title":"Eur.
