This study investigated the applicability of radiomics features of vascular structures within GGNs for predicting invasiveness of GGNs. Methods In total, 165 pathologically confirmed pulmonary GGNs were retrospectively analyzed. The nodules were classified into preinvasive and invasive groups and randomly categorized into training and validation sets in a 7:3 ratio. Four models were constructed and evaluated: radiomics-GGN, radiomics-vascular, clinical-radiomics-GGN, and clinical-radiomics-vascular. The predictive performance of these models was assessed using receiver operating characteristic curves, decision curve analysis, calibration curves, and DeLong's test. Results Significant differences were observed between the preinvasive and invasive groups in terms of age, nodule length, average diameter, morphology, and lobulation sign (P = 0.006, 0.038, 0.046, 0.049, and 0.002, respectively). In the radiomics-GGN model, the support vector machine (SVM) approach outperformed logistic regression (LR), achieving an area under the curve (AUC) of 0.958 in the training set and 0.763 in the validation set. Similarly, in the radiomics-vascular model, the SVM approach outperformed LR. Furthermore, the clinical-radiomics-vascular model demonstrated superior predictive performance compared with the clinical-radiomics-GGN model, with an AUC of 0.918 in the training set and 0.864 in the validation set. DeLong's test indicated significant differences in predicting the invasiveness of pulmonary nodules between the clinical-radiomics-vascular model and the clinical-radiomics-GGN model, both in the training and validation sets (P < 0.01). Conclusion The radiomics models based on internal vascular structures of GGNs outperformed those based on GGNs alone, suggesting that incorporating vascular radiomics analysis can improve the noninvasive assessment of GGN invasiveness, thereby aiding in clinical decision-making and guiding biopsy selection and treatment planning.</p>","PeriodicalId":54215,"journal":{"name":"Current Medical Imaging Reviews","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144058106","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}

Introducing Dual-Energy Computed Tomography (DECT) into clinical practice offers an opportunity to address these issues. DECT has unique advantages in diagnosing and evaluating the efficacy of HCC treatment. It can provide quantitative information on various substances and, through multi-parameter and quantitative parameter analysis, can be used for early detection of HCC, identification of benign and malignant lesions, and monitoring of lymph node metastasis and Microvascular Invasion (MVI). Additionally, DECT provides valuable information for evaluating therapeutic efficacy. This review covers the imaging principles of DECT, including its basic principles, scanner design modes, and Image Reconstruction (IR) techniques.
