Radiology of the Breasts Flashcards
Breast imaging used periodically in asymptomatic patients
Screening mammography
Breast imaging targeted to patients with signs or symptoms of breast cancer
Diagnostic breast imaging
What is the primary purpose of breast imaging
Detect breast carcinoma early and increase survival
Secondary purpose of breast imaging
Detect and evaluate benign disease
Lobules and ducts show up _______ on imaging and fat shows up _________
White
Black
Malignant cells from breast cancer can spread direct,t into the ___________ __________
Infraclavicular nodes
The American cancer society recommends what for early detection of breast cancer
Women should be familiar with how their breasts normally look and feel and should report any changes to health care provider
Women between 40-44 have the option to start screening with a mammogram every year
Women 45-54 should get yearly mammograms
At 55 women can switch to every other year
_____ % of women will experience at least 1 false positive recall, ____% false positive short interval follow up, and _____% false positive
50
17
11
False negative rates for mammography
15%
Breast imaging reporting and data system (BI-RADS) categories
0- incomplete
1- normal; annual
2- benign; annual
3- probably benign, short-term follow up
4- suspicious abnormality, consider biopsy
5- highly suspicious of malignancy, biopsy indicated
6- biopsy proven malignancy, intervention
3D vs 2D mammography
3D (digital breast tomosynthesis) decreases call backs, increases CA dx, better in dense breasts, increased costs
What happens if a breast mass is located in a portion of the breast that is difficult to include in the image
The mammogram may fail to demonstrate the lesion
What is the first step in picking a breast imaging technique for the patient
Determine if they are symptomatic or asymptomatic
T or F: Asymptomatic patients only need routine mammography for screening
True
What are symptoms that indicate further breast imaging?
New or enlarged lumps, skin changes, nipple retraction, eczema good changes, bloody or serous discharge, focal pain or tenderness
