Numerous follow-up examinations and invasive diagnostic procedures, such as fine-needle aspiration, fine-needle biopsies, and thyroidectomies, are performed, leading to potentially costly and time-consuming diagnostic procedures and overtreatment. Most experts and scientific societies (EFSUMB, WFUMB, etc.) encourage the use of multiparametric ultrasound (MPUS) evaluation to improve thyroid nodule characterization due to the continuous technological developments including new ultrasound software (microvascular flow imaging, elastosonography, etc.), contrast media (CEUS), and artificial intelligence (AI). Therefore, the recognition and proper use of new multiparametric ultrasound features of thyroid nodules are essential for minimizing unnecessary interventions and guiding appropriate treatment. The goal of these guidelines is to help initiate use of these features in routine clinical practice. In addition, we analyze the use of MPUS in some emblematic thyroid scenarios, such as cytologically indeterminate nodules, multinodular goiters, and extrathyroidal extension of the malignant nodule, and the usefulness of MPUS as a guide for thyroid biopsy/aspiration and in the staging of cervical lymph nodes. Recommendations based on the level of evidence of the published literature and on the EFSUMB expert group's consensus are given for each question.</p>","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"361-370"},"PeriodicalIF":3.2,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145662499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated whether variations in aortic arch (AA) branching without CoA affect CSAI by comparing fetuses with the classical pattern to those with a brachiobicephalic trunk (BBCT), the most frequent variant. Material and Methods In this prospective cohort study of 335 low-risk singleton pregnancies (19 - 22 weeks of gestation), standardized fetal echocardiography was used to assess AA branching in a sagittal view. Two blinded observers classified branching patterns and calculated CSAI. Results Adequate image quality was obtained in 262/335 (78.2%). 194/262 (74%) fetuses showed a classical pattern and 66 (25.2%) a branching variant. Furthermore, two fetuses (0.8%) due to disagreement on branching pattern. 50/66 (76.8%) fetuses with isolated BBCT were compared with 194 cases with classical AA branching pattern. 16 other variants were excluded. Interobserver agreement showed an intraclass correlation coefficient (ICC) of 0.87 (95%CI: 0.89-0.95). Mean CSAI was significantly lower in BBCT (0.71 ± 0.14) than in classical branching (1.46 ± 0.37; P &lt; 0.001). None required cardiac intervention within two years. Conclusions Targeted fetal echocardiography showed a lower CSAI in cases with BBCT than in classical branching pattern. Future studies are warranted to assess the diagnostic impact of our findings in the setting of suspected CoA. Zielsetzung: Der Carotis-Subclavian-Artery-Index (CSAI) wird in der Diagnostik der Aortenisthmusstenose (CoA) eingesetzt. Wir untersuchten, ob der CSAI bei Feten mit Varianten der Aortenabgänge eine Rolle spielt und verglichen diesen mit Werten bei Aortenbögen mit klassischen Abgängen. Material und Methoden: In dieser prospektiven Kohortenstudie wurden 335 Einlingsschwangerschaften mit niedrigem Risiko zwischen der 19. und 22. Schwangerschaftswoche mittels standardisierter fetaler Echokardiografie untersucht. Der Aortenbogen wurde in sagittaler Ebene dargestellt. Zwei voneinander unabhängige Untersuchende beurteilten verblindet das Abgangsmuster und berechneten den CSAIErgebnisse: Eine ausreichende Bildqualität konnte bei 262 von 335 Fällen (78,2 %) erzielt werden. 194/262 (74 %) Feten zeigten ein klassisches Abgangsmuster, 66 (25,2 %) eine Variante. Bei zwei Feten (0,8 %) bestand Uneinigkeit über das Abgangsmuster. 50/66 (76,8 %) Feten mit isoliertem BBCT wurden mit den 194 Fällen mit klassischem Abgang verglichen; 16 weitere Varianten wurden ausgeschlossen.
