In patients where MRI is contraindicated (certain implantable devices, certain kidney conditions) or in those who prefer to avoid MRI (claustrophobia), molecular breast imaging is a viable alternative. MBI has shown to increase detection of breast cancer in dense breasts by 7-16 cancers per 1000 screens. [1] [3] [5]
Breast ultrasound is also used to perform fine-needle aspiration biopsy and ultrasound-guided fine-needle aspiration of breast abscesses. [8] Women may prefer breast ultrasound over mammography because it is a painless procedure and does not involve the discomfort of breast compression present in mammograms.
Breast MRI is a technology typically reserved for high-risk patients and patients recently diagnosed with breast cancer. [3] Lastly, scintimammography is used in a subgroup of patients who have abnormal mammograms or whose screening is not reliable on the basis of using traditional mammography or ultrasound. [4]
Bleeding into the site of the suspicious lesion caused by the biopsy procedure can appear to look like a complex cyst on ultrasound, which could lead to additional unnecessary management. [13] The false negative rate of the results of a breast biopsy is approximately 1%.
Fibroadenomas are benign breast tumors that are found in approximately 10% of women (primarily ages 15–30). [4] In this procedure which has been approved by the U.S. Food and Drug Administration (FDA), an ultrasound-guided probe is inserted into the fibroadenoma and extremely cold temperatures are then used to destroy the abnormal cells. [5]
For example, a pathologist would examine a mastectomy specimen, even if a previous nonexcisional breast biopsy had already established the diagnosis of breast cancer. Examination of the full mastectomy specimen would confirm the exact nature of the cancer (subclassification of tumor and histologic "grading") and reveal the extent of its spread ...
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
The most common example of molecular imaging used clinically today is to inject a contrast agent (e.g., a microbubble, metal ion, or radioactive isotope) into a patient's bloodstream and to use an imaging modality (e.g., ultrasound, MRI, CT, PET) to track its movement in the body.
