In lung cancer screening, individuals who have a high risk of developing lung cancer but no signs or symptoms of the disease under go low-dose computed tomography (LDCT) scanning of the chest.
CT scanning combines special x-ray equipment with sophisticated computers to produce multiple, cross-sectional images or pictures of the inside of the body. LDCT produces images of sufficient quality to detect many lung diseases and abnormalities using up to 90 percent less ionizing radiation than a conventional chest CT scan.
Ultrasound-guided breast biopsy utilizes ultrasound in order to precisely biopsy a suspicious mass visible at ultrasound. Typically, suspicious microcalcifications are biopsied using stereotactic guidance, while masses are biopsied using ultrasound-guidance. The radiologist may choose to use a skinny needle, core needle or vacuum-assisted biopsy device.
When biopsying suspicious masses, we typically use the Mammotome™ vacuum-assisted needle. This has been shown to be the most sensitive and specific method to perform ultrasound-guided biopsy, minimizing the risk of a nondiagnostic biopsy or sampling error.
Minimally invasive biopsy is preferred to open surgical biopsy. Your physician however may choose to perform a surgical biopsy, particularly if the lesion lies too close to the skin or chest wall, or simply cannot be adequately defined at ultrasound. Additionally, better cosmetic results may be possible with an excision of a likely benign lesion such as a fibroadenoma.
