    Area of Science:

    • Medical Imaging
    • Diagnostic Radiology
    • Preventive Medicine

    Background:

    • Whole-body computed tomography (CT) screening is increasingly discussed for early disease detection.
    • However, the clinical utility and safety profile require thorough evaluation.

    Purpose of the Study:

    • To critically assess the advantages and disadvantages of whole-body CT screening.
    • To provide a balanced perspective for clinicians and patients.

    Main Methods:

    • Review of existing literature on whole-body CT screening.
    • Analysis of reported benefits (e.g., early cancer detection) and risks (e.g., radiation exposure, incidental findings).

    Main Results:

    • Whole-body CT screening can detect certain cancers and other conditions at early, treatable stages.

  • Potential risks include cumulative radiation dose, overdiagnosis, and unnecessary invasive procedures due to incidental findings.

    • Conclusions:

    • The decision to undergo whole-body CT screening should be individualized.
    • A comprehensive understanding of both the benefits and risks is essential for informed patient consent and appropriate clinical application.
