Conventional US and contrast-enhanced ultrasound (CEUS) were required to confirm tumor size, location, and flow perfusion before ablation, then post-ablation CEUS was employed to ascertain the ablation range. Measurements of ablation zone volume, longitudinal and orthogonal diameters, as well as their ratios to ablation energy (R_AZV/E, R_ALD/E, R_AOD/E) were conducted. The influence of CRLM characteristics on ablation efficiency was further analyzed utilizing linear regression. The R_AZV/E is 0.70 cm³/KJ, R_ALD/E is 2.47 mm/KJ, R_AOD/E is 1.70 mm/KJ. Both R_ALD/E and R_AOD/E were inversely associated with ablation energy. Through the single attenuation model, the relationship between ablation longitudinal diameter and ablation energy is finally obtained as Y (mm) = −23.27 * exp (−0.06926 * x) + 42.97. The relationship between orthogonal diameter and ablation energy is Y (mm) = −23.43 * exp (−0.05742 * x) + 34.17. MWA plateau values in longitudinal diameter and orthogonal diameter of ablation are 41.87 and 34.17 mm, respectively. And there is no significant correlation between R_AZV/E and CRLM features (such as CEUS blood supply). Theoretically, considering the safety margin of 5 mm on one side, MWA can completely ablate small CRLM whose diameter is less than 24 mm through a single fixed ablation device. The characteristics of CRLM (such as blood supply of CEUS) have little effect on ablation efficiency.</div></div>","PeriodicalId":49541,"journal":{"name":"Seminars in Ultrasound Ct and Mri","volume":"47 1","pages":"Pages 67-74"},"PeriodicalIF":1.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145758268","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 clinical inconsistency and referral safety of the AI systems were assessed. A total of 595 breast ultrasound reports were independently and blindly assessed by a radiologist and two AI systems—ChatGPT-4o and DeepSeek-V3. Observers provided BI-RADS categories and management recommendations based on the findings section. Diagnostic performance was assessed using histopathological diagnosis or ≥ 24-month follow-up as the standard. Clinical inconsistency means discordance between the BI-RADS categories and corresponding recommendations. Referral safety was quantified using a standardized referral safety score. Interobserver agreement was substantial for both BI-RADS classification (κ = 0.65) and management recommendations (κ = 0.79). The radiologist recorded the highest malignancy detection sensitivity (0.989), followed by DeepSeek-V3 (0.968) and ChatGPT (0.927). Specificity (0.735–0.753) and negative predictive values (0.981–0.997) were comparable across the models, while positive predictive values were limited (0.403–0.436). BI-RADS and management recommendations for ChatGPT were consistent, whereas DeepSeek-V3 had a 0.4% rate (p &gt;.05). Referral safety scores were similar (ChatGPT: 0.44; DeepSeek-V3: 0.46).

We retrospectively analysed 276 patients with gastric SMTs admitted to our hospital from January 2019 to January 2024, all of whom completed gastric DCEUS before surgery or endoscopic biopsy. Pathological findings served as the gold standard, with all malignant/potentially malignant lesions confirmed as GISTs. Patients were divided into two groups: benign SMTs and GISTs. We analyzed clinical and imaging features, and performed binary logistic regression to identify independent risk factors and construct a prediction model. The model's performance was evaluated using receiver operating characteristic (ROC) curves, and internal validation was performed. Time-intensity curves (TIC) were generated using VueBox. Of 276 patients, 183 (66.3%) had GISTs, and 93 (33.7%) had benign SMTs. Multivariate logistic analysis showed that age, gender, location, layer of origin, enhancement degree, and homogeneity were independent predictors for distinguishing GISTs from benign SMTs. The prediction model had an area under the curve (AUC) of 0.84, accuracy of 80%, sensitivity of 73%, specificity of 84%, positive predictive value (PPV) of 70%, and negative predictive value (NPV) of 86%. Internal validation confirmed stability. TIC analysis showed higher PE and shorter RT in GISTs than benign lesions. DCEUS enhances the ability to distinguish GISTs from benign SMTs by integrating tumor morphology, hemodynamics, and clinical features. Heterogeneous high enhancement may serve as a potential imaging marker for intermediate-high-risk GIST stratification. The Nomogram model provides a quantitative tool for individualized risk assessment.</div></div>","PeriodicalId":49541,"journal":{"name":"Seminars in Ultrasound Ct and Mri","volume":"47 1","pages":"Pages 3-16"},"PeriodicalIF":1.9,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145758212","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}

Diagnostic performance was affected by probe frequency, operator skill, patient factors such as obesity or arterial calcification, and reference standard variability. Secondary results involved sparse venous information, where two-thirds of patients undergoing imaging for venous disease had deep vein thrombosis.

Forty-seven patients with locoregional ANPC were prospectively recruited. Two observers independently calculated the MD-PCASL parameters, including the ATT-corrected tumour blood flow (c-TBF), arterial transit time (ATT), and arterial tumour blood volume (aTBV); the SD-PCASL parameters, including the noncorrected tumour blood flow (nc-TBF); and the DCE-MRI quantitative parameters, including K^trans, K_ep, V_e, and V_p. The intra- and interobserver agreement was evaluated via the intraclass correlation coefficient (ICC) and Bland<img>Altman analysis. Relationships between the MD-PCASL, SD-PCASL and DCE-MRI parameters were assessed via Spearman’s rank correlation. The intra- and interobserver reproducibility were excellent, with ICCs ranging from 0.81 to 0.997 and a narrow width of 95% limits of agreement. A good positive correlation was observed between MD-PCASL-related perfusion parameters (c-TBF, aTBV) and DCE-MRI parameters (K^trans, K_ep) (Spearman’s rank correlation coefficients: 0.61 to 0.71, p &lt; 0.001).

Compositional MRI can detect changes in tissue biochemical components before morphological changes occur, and quantitative and semi-quantitative methods can systematically evaluate minor changes in cartilage, exploring new biomarkers for early detection. Under the guidance of deep learning, high-resolution 3-dimensional technology, and super-resolution reconstruction technology, cartilage can be assessed more accurately and quickly, accelerating clinical transformation and enabling early intervention and management in the early stage of reversible cartilage recovery. Knee cartilage MRI can help us better perform early diagnosis of KOA.
