Evidence has been accumulating on the effectiveness of first-trimester anatomy scans. Early mid-trimester fetal scans (eMTSs; 14\u201317 weeks) may have the advantage of visualization of most organs, hence allowing earlier genetic assessment and decision making. Our aim is to examine the effectiveness of eMTSs in identifying fetal anomalies compared to lMTSs. Methods: A retrospective study was conducted based on data from the multidisciplinary prenatal diagnosis clinic in a tertiary center. During the study period (2011\u20132021), an out-of-pocket eMTS in a community setting was offered routinely to the general population. Women who had previously undergone an eMTS and were later assessed due to a fetal anomaly in our clinic were included in the study. The cohort was divided into two groups according to whether the anomaly had been detected during the eMTS. We then compared the groups for factors that may be associated with anomaly detection in eMTSs. We used t-tests and chi-square tests, for quantitative and qualitative variables, respectively, to determine variables related to eMTS anomaly detection, and logistic regression for multivariate analysis. Results: Of 1525 women assessed in our multidisciplinary clinic, 340 were included in the study. The anomaly detection rate of the eMTS compared to the lMTS was 59.1% The eMTS detection rates for specific organ systems were as follows: skeletal, 57%; cardiac, 52%; congenital anomalies of the kidneys and urinary tract (CAKUT), 44%; central nervous system, 32.4%; chest, 33%; and abdominal, 28%. In multivariate analysis, abnormal first-trimester screening (aOR 3.2; 95%CI 1.26\u20138.08) and multiple anomalies (aOR 1.86; 95%CI 1.02\u20133.37) were found to be associated with eMTS anomaly detection. Conclusions: The eMTS detection rate was nearly 60% and was most accurate in detecting skeletal, cardiac, and CAKUT anomalies. Since the eMTS was community-based, this rate likely reflects a \u201creal-world\u201d scenario. Our findings support consideration of performing an eMTS or first-trimester scan routinely for earlier diagnosis and decision making, as an adjunctive to lMTSs. Future studies will examine the cost-effectiveness of early scans.<\/jats:p>","DOI":"10.3390\/jcm13195750","type":"journal-article","created":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T03:44:13Z","timestamp":1727408653000},"page":"5750","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Detection Rate of Fetal Anomalies in Early Mid-Trimester Compared to Late Mid-Trimester Detailed Scans: Possible Implications for First-Trimester Sonography"],"prefix":"10.3390","volume":"13","author":[{"given":"Zangi","family":"Yehudit","sequence":"first","affiliation":[{"name":"Department of Obstetrics & Gynecology, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2543-664X","authenticated-orcid":false,"given":"Michaelson-Cohen","family":"Rachel","sequence":"additional","affiliation":[{"name":"Department of Obstetrics & Gynecology, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"},{"name":"Medical Genetics Unit, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2960-9533","authenticated-orcid":false,"given":"Weiss","family":"Ari","sequence":"additional","affiliation":[{"name":"Medical Genetics Unit, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shen","family":"Ori","sequence":"additional","affiliation":[{"name":"Medical Genetics Unit, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mazaki","family":"Eyal","sequence":"additional","affiliation":[{"name":"Medical Genetics Unit, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9859-469X","authenticated-orcid":false,"given":"Sela Hen","family":"Yitzhak","sequence":"additional","affiliation":[{"name":"Medical Genetics Unit, Shaare Zedek Medical Center, Faculty of Medicine, Hebrew University School of Medicine, Jerusalem 9112102, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.3310\/hta4160","article-title":"Ultrasound screening in pregnancy: A systematic review of the clinical effectiveness, cost effectiveness and women\u2019s view","volume":"4","author":"Bricker","year":"2000","journal-title":"Health Technol.
