Computed Tomography01:10

Computed Tomography

9.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

    Summary

    Advancements in digital mammography and 3-D breast imaging, or digital breast tomosynthesis (DBT), are improving breast cancer detection. Research is ongoing to clarify DBT's role in screening, especially with changing recommendations and increased focus on breast density.

    Area of Science:

    • Radiology
    • Oncology
    • Medical Imaging Technology

    Background:

    • Breast cancer screening guidelines are evolving.
    • Breast density is increasingly recognized as a crucial factor in screening effectiveness.
    • Digital mammography is the standard, with digital breast tomosynthesis (DBT) gaining adoption.

    Purpose of the Study:

    • To review current research on digital mammography and DBT.
    • To explore the emerging role of 3-D breast imaging in cancer detection.
    • To discuss the implications of these technologies for breast cancer screening.

    Main Methods:

    • Review of recent clinical trials and research findings on digital mammography.
    • Analysis of studies evaluating the performance of digital breast tomosynthesis (DBT).
