The differences in benign and malignant breast tumors are not only within the nodules but also involve changes surrounding tissues. Radiomics can reveal many details that discernible to naked eye. This study aimed distinguish between using an ultrasound-based intra- peritumoral radiomics model.This retrospectively collected information from 379 patients with Breast Imaging Reporting Data System (BI-RADS) category 3-5 clear pathological diagnosis of screened by routine ultrasound examination Sixth People's Hospital Affiliated Medical College Shanghai Jiao Tong University January 2017 December 2022. largest dimension lesion on 2D image was selected outline area interest which conformally outwardly expanded automatically 5 mm extract peritumor features. included cases were randomly divided into training sets test a ratio 7:3. optimal features models retained statistical machine learning methods dimensionality reduction, logistic regression used as classifier build intratumoral model combined intratumoral-peritumoral model, respectively; through single-factor multifactor regression, could predict screened. clinical imaging established selecting independent risk factors univariate multifactorial regression.Among BI-RADS nodules, there 124 255 nodules; aged 14 88 (46.22±15.51) years, age differences, score, mass diameter statistically significant (P>0.05). had under curve (AUC) 0.840 [95% confidence interval (CI): 0.766-0.914] set.

Background Differentiating between benign and malignant breast masses is critical for clinical decision-making. Automated volume scanning (ABVS) provides high-resolution three-dimensional imaging, addressing the limitations of conventional ultrasound. However, impact peritumoral region size on predictive performance has not been systematically studied. This study aims to optimize diagnostic by integrating radiomics features data using multiple machine-learning models. Methods retrospective included ABVS images from 250 patients with masses. Radiomics were extracted both intratumoral regions (5, 10, 20 mm). These features, combined data, used develop models based four algorithms: Support vector machine, random forest, extreme gradient boosting, light boosting machine (LGBM). Model was evaluated area under receiver operating characteristic curve (AUC), calibration curves, decision SHapley Additive exPlanations (SHAP) analysis employed interpretability. Results The inclusion improved varying degrees, model incorporating a 10 mm achieving highest overall accuracy. Combining further enhanced performance. LGBM outperformed other algorithms across subgroups, maximum AUC 0.909, an accuracy 0.878, F1-score 0.971. SHAP revealed contribution key improving Conclusion demonstrates value mass diagnosis, optimized enhancing emerged as preferred algorithm due its superior findings provide strong support application imaging future multicenter studies, highlighting importance microenvironmental in diagnosis.

Background: In recent years, computer-aided diagnosis (CAD) systems have played an important role in breast cancer screening and diagnosis. The image segmentation task is the key step a CAD system for rapid identification of lesions. Therefore, efficient network necessary improving diagnostic accuracy screening. However, due to characteristics blurred boundaries, low contrast, speckle noise ultrasound images, lesion challenging. addition, many proposed tumor networks are too complex be applied practice. Methods: We developed attention gate dilation U-shaped (GDUNet), lightweight, model. This model improves inverted bottleneck, integrating it with tokenized multilayer perceptron (MLP) construct encoder. Additionally, we introduce lightweight (AG) within skip connection, which effectively filters low-level semantic information across spatial channel dimensions, thus attenuating irrelevant features. To further improve performance, innovated AG (AGDT) block embedded between encoder decoder order capture critical multiscale contextual information. Results: conducted experiments on two datasets. experiment’s results show that compared UNet, GDUNet could reduce number parameters by 10 times computational complexity 58 while providing double inference speed. Moreover, achieved better performance than did state-of-the-art medical architecture. Conclusions: Our method can achieve advanced different datasets high efficiency.
