Initial CUS demonstrating CTG echogenicity was performed at a mean of 15.7 postnatal days; echogenicity was bilateral in 9 (50%) and unilateral in 9 (50%), with teardrop-like morphology in 10 (55.6%). MRI with SWI was performed at a mean of 29 postnatal days (range 2 to 90 d). No hemorrhagic changes were observed in the CTG region on SWI. Three patients (16.7%) had normal MRI findings, 15 (83.3%) showed nonhemorrhagic abnormalities, including edema, thin corpus callosum, subependymal cysts, ventricular dilatation, or cortical malformations. This study demonstrates a discordance between CUS and SWI-MRI findings in infants with CTG echogenicity. The presence of term infants and bilateral involvement suggests that CTG echogenicity may be a nonspecific imaging finding that can reflect a variable pathophysiological process. Therefore, confirmatory MRI with SWI may be valuable for accurate diagnosis and clinical decision-making in both preterm and term neonates with isolated CTG echogenicity.</p>","PeriodicalId":49116,"journal":{"name":"Ultrasound Quarterly","volume":"42 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146214446","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}

The aim of our study is to determine the correlation between hepatic steatosis grading obtained through attenuation measurement and grayscale ultrasound assessment performed by both a physician and a resident. In addition, we aim to evaluate the reproducibility of results obtained using both methods. A prospective study was conducted on 112 patients who underwent 2 double-blinded ultrasound examinations executed by an experienced radiologist with 30 years of expertise and a fifth-year resident from October to December 2023. Consequently, for each patient, a grayscale assessment of liver fat and attenuation coefficient measurement was done by the 2 readers, and graded accordingly. For attenuation coefficient, 5 measurements were taken with respect to the quality criteria set by the vendor. No significant difference was shown in the grading of liver fat using subjective method and attenuation imaging, obtained by the physician and the resident. Our results showed good reproducibility for grading fat liver using grayscale (Cohen Kappa=0.682) and attenuation imaging (Cohen Kappa=0.729) and excellent agreement for attenuation coefficient (ICC=0.956, 2k model).
