The Role of Ultrasound in Breast Imaging: A Comprehensive Insight by Valence Medical Imaging, Toronto

Breast imaging plays an indispensable role in detecting and diagnosing breast abnormalities. While most people are familiar with mammograms, not everyone is aware of the importance and utility of breast ultrasound. At Valence Medical Imaging in Toronto, we offer an array of imaging services tailored to the specific needs of our clients from Toronto, Brampton, and Whitby, to Niagara Falls. This article sheds light on the essential role ultrasound plays in breast imaging.


Understanding Breast Imaging: An Overview


Breast imaging is a collective term for the various techniques used to visualize the internal structures of the breast. The primary goal is to detect and diagnose breast cancer at its earliest stages, thus increasing the chances of successful treatment. The most commonly known imaging type is the digital mammogram. However, other methods, such as breast tomosynthesis and breast ultrasound, also play vital roles.


Digital Mammogram vs. Breast Ultrasound


A digital mammogram captures two-dimensional images of the breast. It’s the frontline tool for breast cancer screening, especially in women aged 40 and above. Key benefits of digital mammograms include their ability to detect calcifications and their effectiveness in women with non-dense breasts.


On the other hand, breast ultrasound uses sound waves to produce images of the breast tissue. Unlike a mammogram, it doesn’t involve radiation exposure, making it a safer option for certain groups, such as pregnant women.


The Significance of Breast Ultrasound


Here’s why breast ultrasound holds significance in the realm of breast imaging:


  • Dense Breasts: For women with dense breast tissue, a mammogram might not always provide a clear image. Ultrasound is particularly useful in such cases, as it can differentiate between benign and potentially malignant lesions in dense breasts.
  • Diagnostic Clarification: Sometimes, a diagnostic mammogram might reveal an abnormality that requires further investigation. An ultrasound can help determine whether the abnormality is solid (potentially cancerous) or fluid-filled (like a cyst).
  • Breast Biopsy Guidance: If there’s a need for a breast biopsy, ultrasound can guide the radiologist in accurately targeting the lesion or lump.
  • No Radiation Exposure: As mentioned, ultrasounds don’t involve radiation, making them an ideal alternative for those concerned about radiation exposure.


Complementary Role with Other Imaging Techniques


While breast ultrasound is powerful, it often works in tandem with other imaging techniques:


  • Breast Tomosynthesis: Also known as 3D mammography, breast tomosynthesis captures multiple images from different angles, providing a more detailed view. In cases where both ultrasound and tomosynthesis are used, radiologists can get a comprehensive understanding of any detected abnormalities.
  • BI-RADS Classification: The Breast Imaging-Reporting and Data System (BI-RADS) classification assists radiologists in categorizing breast abnormalities based on their likelihood of malignancy. Ultrasound, along with mammography, aids in this classification, ensuring patients receive timely and appropriate care.
