The role of HA in fetal growth and pregnancy complications is underexplored. This study investigates HA Doppler in gestational diabetes mellitus (GDM) and its relationship with HbA1c, comparing results to healthy pregnancies.Methods: This prospective case-control study included 63 pregnant women (30 insulin-treated GDM, 33 without GDM) between 32 and 36 weeks gestation (Figure 1). Doppler of the umbilical artery (UA), middle cerebral artery (MCA), ductus venosus (DV), and HA was performed by a high-risk pregnancy specialist.Results: Demographics and lab parameters were similar across groups. GDM cases had higher HA peak systolic velocity (PSV) and lower pulsatility index (PI) versus controls. HA PSV positively correlated with HbA1c.Conclusion: Our findings suggest a link between GDM and HA Doppler changes. Larger studies are needed to evaluate the implications of these changes on prenatal development.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143995190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Iodine concentration (mg/mL) and spectral HU values were measured with circular regions of interest on iodine maps. Metastatic nodes included 27 from squamous cell carcinoma (SCC), 19 from lymphoma, and 6 from papillary thyroid carcinoma (PTC).Results: Metastatic lymph nodes had lower iodine levels than reactive nodes (1.45 vs. 1.85 mg/mL, p = 0.011). No significant difference in spectral HU values was found (117 vs. 111 HU, p = 0.328). An iodine threshold of 1.62 mg/mL demonstrated 71% sensitivity and 77% specificity for detecting malignancy (AUC = 0.673, 95% CI: 0.54-0.80, p = 0.011). SCC metastases had lower iodine levels than reactive nodes (1.33 vs. 1.85 mg/mL, p < 0.001), while PTC metastases had higher levels (2.39 vs. 1.85 mg/mL, p = 0.038).Conclusion: DECT iodine quantification improves the detection of cervical lymph node metastases, particularly in cases with equivocal size criteria. Incorporating iodine measurements with tumor type knowledge improves diagnostic accuracy, aiding in prognosis and treatment planning.","PeriodicalId":15386,"journal":{"name":"Journal of Clinical Ultrasound","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143995184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare the performances of the contrast agents Sonazoid and SonoVue in quantitative analysis in the contrast-enhanced ultrasound (CEUS) of peripheral lung cancer lesions (PLCLs).Methods: This retrospective study included patients with PLCLs between January 2021 and January 2024. They were divided into the Sonazoid-CEUS (50 patients) and SonoVue-CEUS (53 patients) groups. In the CEUS video, lesions and adjacent normal lung tissues were selected as regions of interest to obtain time-intensity curves. Seven CEUS indicators were used to compare the performances of the two contrast agents.Results: The arrival times (ATs) were 13.1 ± 5.2 s and 11.5 ± 3.7 s for PLCLs (p = 0.087), respectively, and 8.0 ± 4.1 s and 7.0 ± 4.2 s for adjacent lung tissues (p = 0.197), respectively, in the Sonazoid and SonoVue groups. The peak intensity (PI) and area under the curve (AUC) of the lesions in the Sonazoid group were significantly lower than those in the SonoVue group (PI: 25.0 ± 11.5 vs. 35.8 ± 7.9, p < 0.001; AUC: 2365.2 ± 1708.2 vs. 4309.5 ± 1252.1, p < 0.001). The time to peak (TTP), mean transition time (MTT), and lesion-lung PI difference (ΔPI) in the Sonazoid group were significantly higher than those in the SonoVue group (TTP: 36.3 ± 13.8 s vs. 24.4 ± 8.7 s, p < 0.001; MTT: 119.6 ± 45.3 s vs. 80.6 ± 21.4 s, p < 0.001; ΔPI: 14.3 ± 10.9 vs. 8.4 ± 6.1, p < 0.01).Conclusion: Sonazoid and SonoVue exhibited comparable quantitative performances in CEUS of PLCLs; the higher ΔPI of Sonazoid suggests it may enhance the contrast between lesions and adjacent tissues.

Propensity-score matching (PSM) analysis was employed to reduce confounding biases.Results: After PSM, two matched groups (168 pairs, n = 336 patients) were generated. There were no significant differences in the modified Rankin Scale (mRS) scores of 0-2 or 0-1 at 3 months between the two groups (both p > 0.05).
