Tissue harmonic imaging (THI) is also a standard feature of most entry-level ultrasound units for a reduction in reverberation and near field artifacts. High-frequency ultrasound has improved over the past decade with standard linear frequency probes ranging from 7.5 MHz to 23 MHz, with high density or single crystal probe components, which improves lateral resolution. The use of breast ultrasound as a sole screening tool is inappropriate.

Breast parenchyma (hyperechoic, fibroglandular soft tissue).Fat (hypoechoic, subcutaneous fat lobules).Skin (hyperechoic, white fibrous bands).The three main anatomical zones of the breast are the pre-mammary, mammary, and retro-mammary zones, consisting of fatty tissue, fibroglandular tissue, and muscular tissue.įrom a sonographic point of view (Image 2), the breast is divided into various hypoechoic and hyperechoic layers: The basic breast anatomy comprises 15 to 20 lobules, each consisting of smaller breast ducts, known as the terminal duct lobular units (TDLUs). All the ducts drain into a single lactiferous sinus towards the nipple. Anatomy and Physiologyīreast ultrasound is often used to localize palpable and non-palpable masses before surgical excision. The sensitivity for breast cancer detection using both mammography and ultrasound increases to 97.3%, with the false positive rate of ultrasound measured as 2.4%. Due to this reason, ultrasound, and magnetic resonance imaging (MRI) have been expanding their role as part of supplementary breast screening procedures. Although mammography remains the gold standard for breast cancer screening, it presents certain imaging limitations with dense breast parenchyma. Outline interprofessional team strategies for improving care coordination and communication to advance breast ultrasound and improve outcomes.īreast ultrasound has developed into a practical solution for the evaluation of breast disease.Review the clinical significance of breast ultrasound as a diagnostic tool for the detection of breast malignancy.
