Masses are significantly more conspicuous on breast CT images compared with screen-film mammograms, but microcalcification lesions are not as well visualized on our early-generation dedicated breast CT images

The higher signal-to-noise ratio at 3.0 T is clearly advantageous and the increased radiofrequency absorption in tissues at higher field strengths is disadvantageous. All other effects, however, can be both advantageous or disadvantageous, depending on the desired image contrast and/or the intended clinical application.

The results reported here corroborate the trend in favor of improved diagnostic accuracy of digital mammography over film for pre- and perimenopausal women younger than 50 years with dense breasts

We found that lesion margin and presence of calcifications on images, as well as cancer stage at diagnosis, are significantly associated with human epidermal growth factor receptor type 2 status in patients with estrogen receptor negative breast cancer

Axillary Lymph Nodes: US-guided Fine-Needle Aspiration for Initial Staging of Breast Cancer Correlation with Primary Tumor Size

US-guided fine-needle aspiration is useful in the initial axillary staging of breast cancer; the sensitivity of the technique increases with increasing tumor size

Computer-aided Detection in Full-Field Digital Mammography: Sensitivity and Reproducibility in Serial Examinations

When a computer-aided detection system was applied to initial and short-term follow-up digital mammograms, sensitivities were, respectively, 91% and 89% for masses and 100% and 100% for microcalcifications; overall false-positive mark rates were 0.29 mark per image and 0.27 mark per image at initial and follow-up digital mammography, respectively

Mammographic, US, and MR Imaging Phenotypes of Familial Breast Cancer

Based on the results obtained in our cohort, we propose that this relatively low sensitivity of MR imaging in women at increased familial risk is due to the fact that these cancers may exhibit unusual imaging features also in breast MR imaging
