Receiver operating characteristic (ROC) curves are frequently used to compare the accuracy of two or more imaging modalities. This paper addresses the use of ROC analysis to evaluate the speed and accuracy of digital mammography, as compared to conventional film-screen mammography.

Breast cancer remains a leading cause of death among women throughout the world. The incidence is increasing globally and the disease remains a significant public health problem. Mammography is currently the best method to detect early breast cancer before it becomes clinically palpable. The use of mammography results in a 25% to 30% decreased mortality rate in screened women compared with cont...

Still there is a passionate debate in medical world about the best screening method for Breast Cancer. Early detection is an effective way to diagnose and manage breast cancer. Mammography is the most widely used screening modality, with solid evidence of benefit for women aged 40 to 74 years. Even then it has also undergone increased scrutiny for False-Positives with additional testing which i...

Mammography machines must meet high requirements to ensure the quality of generated images. On other hand, due use ionizing radiation, there is a need minimize dose received by patients. To optimize both these parameters (dose and image quality), response characteristics detectors and, depending on composition breasts, physical contrast examined structures should be considered. This study aimed...

For the past several decades, mammography has been the cornerstone of screening for breast cancer. Technology has improved greatly, as has radiologists’ skills in interpreting fi lms. Many studies have attempted to analyze the contribution of regular mammography screening to decreasing mortality from breast cancer. These studies have demonstrated varying results. In 2001, Olsen and Gotzsche pub...
