3D Mammography (Tomosynthesis)

Explanation of 3D Mammography Technique

3D mammography, or tomosynthesis, is an advanced technique providing a three-dimensional breast view. Unlike traditional 2D mammography, which captures a single image of the breast, tomosynthesis takes multiple X-ray images from various angles. These images are then reconstructed into a three-dimensional representation of the breast tissue, allowing for a more comprehensive evaluation.

Advantages over Traditional 2D Mammography

3D mammography offers several advantages over traditional 2D mammography. Firstly, it provides improved visualization of breast tissue. The multiple images obtained from different angles enable radiologists to examine the breast tissue layer by layer, reducing the overlap of structures and enhancing the ability to detect small abnormalities.

One of the most significant advantages of 3D mammography is its ability to detect Stage 1 Breast Cancer at higher rates than traditional 2D mammography. The improved visualization and enhanced accuracy of tomosynthesis enable the detection of smaller tumors and subtle changes in breast tissue that may indicate early-stage cancer.

Reduction in False Positives and Callbacks

Another crucial benefit of 3D mammography is reducing false positives and callbacks. False positives can cause anxiety and additional diagnostic procedures for patients. With tomosynthesis, radiologists can better distinguish between benign findings and suspicious abnormalities, resulting in a decrease in false-positive results.

The improved accuracy of 3D mammography also reduces unnecessary callbacks for further imaging or additional procedures. Tomosynthesis’ three-dimensional picture allows radiologists to analyze the breast tissue in greater detail, minimizing the need for additional imaging or biopsies.

Contrast-Enhanced Mammography

Introduction to Contrast-Enhanced Mammography

A contrast agent is injected into the circulation before mammographic imaging in contrast-enhanced mammography, a cutting-edge procedure. The contrast agent enhances the visibility of blood vessels and areas of increased blood flow within the breast tissue, making small tumors more conspicuous on the mammogram images.

How it Improves the Visibility of Small Tumors

Contrast-enhanced mammography improves the visibility of small tumors by exploiting the increased blood supply and angiogenesis associated with cancerous growth. The injected contrast agent highlights the areas of increased blood flow, making them more discernible on the mammogram images. This enhanced visibility helps radiologists detect small tumors that might have been challenging to identify on conventional mammograms.

Automated Breast Ultrasound (ABUS)

Overview of ABUS Technology

Automated Breast Ultrasound (ABUS) is an advanced imaging technique that utilizes high-frequency sound waves to create detailed images of the breast. Unlike traditional handheld ultrasound, ABUS employs an automated scanning system that moves the ultrasound transducer in a standardized manner, ensuring consistent and comprehensive coverage of the entire breast.
