When a suspicious finding is seen on a breast magnetic resonance imaging (MRI) examination and other imaging and clinical examinations are negative, the only way to perform a biopsy of the lesion is by using MRI guidance. All facilities that…
More than 2 million women in the United States have undergone breast implantation since the 1960s, either for cosmetic augmentation or breast reconstruction. During this time, both the silicone controversy and the known complications of breast augmentation have necessitated an…
The breast undergoes significant anatomic and histologic changes after intervention. Posttreatment imaging findings have been thoroughly described for mammography and breast ultrasound, but only isolated descriptions of postsurgical breast changes seen on dynamic contrast enhanced (DCE) breast magnetic resonance imaging…
In the absence of distant metastatic disease, breast cancer staging is based on the extent of local-regional disease in the breast and axilla. The American Joint Committee on Cancer TNM system is used to provide breast cancer patients and their…
Some benign pathologic entities of the breast, when diagnosed at image-guided core needle biopsies, have the potential to be upgraded to invasive carcinoma or ductal carcinoma in situ (DCIS) upon complete excision by surgery. These entities are collectively categorized as…
The current practice of breast imaging calls for using breast magnetic resonance imaging (MRI) only on high-risk patients with appropriate indications to maximize cancer detection yield and minimize the false-positive rate. Even with careful selection of patients, radiologists usually encounter…
Breast magnetic resonance imaging (MRI) has become an important part of the work-up of patients with newly diagnosed breast cancers. Although no large studies have proved a survival advantage, and questions remain as to whether preoperative MRI has reduced re-excision…
Ductal carcinoma in situ (DCIS) now makes up 20% to 30% of newly diagnosed breast cancers, an increase in detection that is largely attributed to the advent of screening mammography. Before the advent of screening mammography, DCIS made up about…
Breast cancer remains the second leading cause of cancer death in women. Mammography is the single large-scale method currently employed in screening for breast cancer in asymptomatic women. Although the effect of mammography in decreasing mortality is debated, multiple studies…
Optimal breast magnetic resonance imaging (MRI) interpretation depends on the image reader’s ability to both detect and accurately characterize contrast enhanced breast lesions. Detecting areas of enhancement involves the tedious process of comparing the precontrast and postcontrast sequences. This process…
