Three-Dimensional Digital Breast Tomosynthesis: An Introduction
(1 Credit)
ASRT Accredited
|
|
Breast cancer is a leading cause of morbidity and mortality, although early detection may significantly increase survival rates. When diagnosed early, the 5-year survival rate for patients with breast cancer is greater than 90%. A recently-approved three-dimensional breast imaging technique, digital breast tomosynthesis (DBT) provides views of the entire breast or individual cross-sectional slices, thereby lessening the problem of overlapping tissue leading to fewer false-positive findings, and reducing the number call-backs for additional testing. DBT can also better depict breast lesions and may eventually replace spot compression views. This article aims to describe this new technology and discuss how it may affect breast imaging in the near future. |

Stereotactic Breast Biopsy

Breast biopsy is an important procedure for breast cancer screening and diagnosis. Although most abnormalities identified in mammography are not breast cancer, approximately 2% of women must undergo further testing. For many years, surgical breast biopsy was the only option for obtaining an adequate tissue specimen. Stereotactic biopsy, a less invasive alternative to surgical biopsy, has a high rate of accuracy and good safety and patient acceptability. The stereotactic method may be used with a variety of biopsy devices and needle sizes to quickly obtain tissue samples for histologic assessment. Proper technique, combined with careful analysis of previous mammograms has proven to be a successful option to quickly obtain tissue samples for histologic assessment. |

Breast Implants and Mammography: Clinical Challenges
(1 Credit)
ASRT Accredited
|
|
Breast augmentation is the most commonly performed cosmetic surgical procedure in the United States having increased by 39% from 2000 to 2009. The safety of implants has been challenged in recent years, and the potential for implants to interfere with mammography is a topic of continuing debate. The most important components of successful long-term cancer screening in women who have undergone breast augmentation or reconstruction are technologists who are knowledgeable about the proper precautions to take during mammography and the specific techniques that maximize the amount of breast tissue imaged. This article will review the types of implants and procedures currently available and will highlight precautions and radiographic techniques used to provide effective imaging services in women with implants. |

Diffusion-Weighted Magnetic Resonance Imaging of the Liver
(1 Credit)
ASRT Accredited
|
|
Magnetic resonance diffusion-weighted imaging (DWI) of the brain is a well-established and reliable modality for evaluating many neurologic conditions, but the use of DWI for examinations of other body organs is not as common because of technical challenges, such as respiratory and cardiovascular motion. Also, the cellular nature of some abdominal organs makes the interpretation of DWI more difficult. Despite these difficulties, DWI of the liver is becoming more useful as radiologists become more familiar with the technique. This article, which is the second in a series of 2, concentrates on DWI of the liver—how it differs from DWI of the brain, why it is being used more frequently despite the challenges it presents, and how to optimize DWI sequences for applications outside the cranium. |
