Although studies have been conducted to classify ultrasound images of tumors of the liver into four categories (liver cysts (Cyst), liver hemangiomas (Hemangioma), hepatocellular carcinoma (HCC), and metastatic liver cancer (Meta)), no studies with additional information for deep learning have been reported. Therefore, we attempted to improve the classification accuracy of ultrasound images of hepatic tumors by adding hepatitis virus infection information to deep learning.Methods: Four combinations of hepatitis virus infection information were assigned to each image, plus or minus HBs antigen and plus or minus HCV antibody, and the classification accuracy was compared before and after the information was input and weighted to fully connected layers.Results: With the addition of hepatitis virus infection information, accuracy changed from 0.574 to 0.643. The F1-Score for Cyst, Hemangioma, HCC, and Meta changed from 0.87 to 0.88, 0.55 to 0.57, 0.46 to 0.59, and 0.54 to 0.62, respectively, remaining the same for Hemangioma but increasing for the rest.Conclusion: Learning hepatitis virus infection information showed the highest increase in the F1-Score for HCC, resulting in improved classification accuracy of ultrasound images of hepatic tumors.","PeriodicalId":50130,"journal":{"name":"Journal of Medical Ultrasonics","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003803","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}

Singleton cephalic pregnancies ≥ 37 weeks were included. The digital vaginal examination (DVE) findings, TUS station, and angle of progression (AoP), an ultrasound parameter commonly used for assessing labour progression, were obtained by individual obstetricians who were blinded to the results in all cases. The TUS station and DVE findings and AoP and DVE findings of the participants were compared. A second cohort requiring forceps delivery was analyzed to explore the relationship between TUS station and delivery difficulty.Results: In the quantitative assessment of fetal head descent, the TUS station correlated with DVE findings. During the resting phase of labour, the TUS cut-off value for an easy forceps delivery was 2 cm, with a sensitivity of 85%; the maximum AUC value was 0.9 (95% confidence interval [CI]: 0.73-0.96). At the time of labour, the TUS cut-off value for an easy forceps delivery was 2.9 cm, with a sensitivity of 85%; the maximum AUC value was 0.8 (95% CI 0.65-0.96).Conclusion: The TUS station may serve as a valuable and objective parameter for consideration in decisions regarding forceps delivery.","PeriodicalId":50130,"journal":{"name":"Journal of Medical Ultrasonics","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144003652","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 IFP is a key factor in knee osteoarthritis (OA); however, its dynamic feature during walking remains unknown. This study aimed to investigate whether the morphological changes in the IFP during walking involve specific features for patients with knee OA.Methods: Twelve patients with knee OA, 12 healthy young volunteers, and 12 healthy elderly volunteers were recruited. The IFP was evaluated using ultrasonography, and dynamics were recorded in video mode during walking. The IFP value was identified as the thickness between the patellar tendon and proximal tibial line. The morphological change in the IFP (ΔIFP) was shown as the difference in IFP value between maximum and at initial contact on the waveform. Kinematics and kinetics data were evaluated using a three-dimensional motion analysis system synchronized with ultrasonography, and the knee flexion angle and its moment in the stance phase were evaluated.Results: In the patients with knee OA, the ΔIFP was lower than that in healthy volunteers, but there was no difference between control groups (knee OA: 1.4 ± 0.3 mm, elderly control: 1.8 ± 0.2 mm, young control: 2.1 ± 0.5 mm, p < 0.05). In all the groups, there was no significant correlation between the IFP values and kinetic parameters, including the range of knee flexion angles and gait speed.Conclusion: Insufficient morphological changes in the IFP during walking could be a feature of knee OA.","PeriodicalId":50130,"journal":{"name":"Journal of Medical Ultrasonics","volume":" ","pages":"219-226"},"PeriodicalIF":1.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12018517/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
