In 2009, China launched a breast cancer screening programme for women living in rural areas who were aged 35–64 years and at average risk. The programme used ultrasound combined with clinical breast examination as the primary screening tool. In 2012, breast cancer screening was done by use of...
Breastcancer screeningaims to reduce mortality, but the screening process introduces harm as well as benefit. Over the past several decades, mammographicbreast cancer screeninghas been the subject of controversy with questions focusing on whether the benefits outweigh the harms. In light of this debat...
Tomosynthesis, a technique that can produce pseudo 3-D reconstructions, could top traditional mammography in breast cancer screening and detection, a recent study suggests. Researchers at Emory University have found that digital tomosynthesis imaging offers more sensitivity and specificity than mammography...
PRAUCs对于读者从0.244到0.453不等(平均值:0.364,标准差:0.0496)。研究还评估了人类-机器混合模型的准确性,其预测是放射科医生和模型预测的线性组合。混合模型的平均AUC为0.891,平均PRAUC为0.431,表明模型可以作为工具协助放射科医生阅读乳腺癌筛查检查。 讨论和结论:研究者们通过利用大型训练集,成功构建了一个能够准确...
The algorithm also computes the sensitivity and leadtime distribution. It allows for arbitrary age groups, detection thresholds and screening intervals and may contribute to the design of future screening trials. 展开 关键词: Breast cancer screening Tumor size Tumor growth rate Mathematical model ...
The rapid development of deep learning, a family of machine learning techniques, has spurred much interest in its application to medical imaging problems. Here, we develop a deep learning algorithm that can accurately detect breast cancer on screening mammograms using an “end-to-end” training app...
Breast cancer, an adversary with a profound impact on women worldwide, underscores the paramount importance of early detection. Within the realm of this critical fight lies the cornerstone of preventative care: screening mammography. This technique is not merely a medical procedure but a gateway to...
Breast cancer is a global health issue affecting 2.3 million women per year, causing death in over 600,000. Mammography (and biopsy) is the gold standard for screening and diagnosis. Whilst effective, this test exposes individuals to radiation, has limit
Population-based screening might be associated with a higher likelihood of a (ultra)low risk tumor assessed by the 70-gene signature (MammaPrint) (ultralow defined as indexscore >0.6, no distant metastasis observed at 5 years in the original 78 patients). The aim of this study is to determi...
Nonlinear Microwave Imaging for Breast-Cancer Screening Using Gauss–Newton's Method and the CGLS Inversion Algorithm Breast-cancer screening using microwave imaging is emerging as a new promising technique as a supplement to X-ray mammography. To create tomographic images... T Rubek,PM Meaney,P ...
