Computed Tomography01:10

Computed Tomography

4.5K
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...

Radiological Investigation I: X-ray and CT

232
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Summary

Radiologists can accurately assess breast density using chest CT scans, similar to mammograms. Reporting this finding on CT scans can help detect breast cancer risks earlier.

Area of Science:

  • Radiology
  • Oncology
  • Medical Imaging

Background:

  • Mammograms screen for breast cancer and report breast density, a risk factor.
  • Chest CT scans are increasingly common for lung cancer screening.
  • CT scans can reveal incidental findings like breast density.

Purpose of the Study:

  • To evaluate the reliability of breast density grading on chest CT scans.
  • To compare chest CT breast density grading with mammography.
  • To determine the inter-reader agreement for breast density assessment on chest CT.

Main Methods:

  • Previous research established reliable breast density grading on chest CT.
  • Comparison of breast density grading between chest CT and mammography was performed.
  • Inter-reader agreement for chest CT breast density grading was assessed.

Main Results:

  • Breast density can be reliably graded on chest CT scans.
  • Chest CT breast density grading is comparable to mammographic grading.
  • Inter-reader agreement for breast density assessment is higher on chest CT than mammography.

Conclusions:

  • Thoracic radiologists should report breast density findings from chest CT scans.
  • Reporting breast density on chest CT can aid in early breast cancer detection.
  • This practice aligns with federal recommendations for mammography reporting.
