Radiological services throughout the world

J Brederhoff, N T Racoveanu

    Diagnostic Imaging
    |January 1, 1982
    PubMed
    Summary

    Radiological services in developing countries remain underdeveloped, with limited access to diagnostic X-ray services for most of the population. A proposed three-tiered pyramid structure, starting with Basic Radiological Services, aims to improve healthcare access.

    Area of Science:

    • Public Health
    • Radiology
    • Global Health

    Background:

    • Doctor-to-population ratios and radiological services in developing nations show minimal improvement over the past decade.
    • Radiological services are among the least developed medical branches in developing countries' healthcare systems.
    • Current data indicates that only 220 million out of 1.2 billion people in 89 countries have access to adequate diagnostic X-ray services.

    Purpose of the Study:

    • To analyze the current state of radiological services in developing countries.
    • To propose a structured, tiered approach to improve diagnostic X-ray service accessibility and quality.
    • To highlight the need for accessible X-ray facilities within communities.

    Main Methods:

    • Analysis of population/machine/personnel ratios, morbidity patterns, X-ray examination rates, film usage, and procedure types across 89 countries.
    • Evaluation of existing diagnostic X-ray service structures in developing nations.
    • Conceptualization of a three-level pyramid model for radiological services.

    Main Results:

    • Significant disparities exist in access to adequate diagnostic X-ray services, with a vast majority of the population underserved.
    • The proposed pyramid structure (Basic, General Purpose, Specialized Radiological Service) is largely absent in most countries.
    • A substantial amount of X-ray film is wasted, indicating inefficiencies in service delivery.

    Conclusions:

    • The current state of radiological services in developing countries is inadequate to meet population needs.
    • Implementing a tiered structure, particularly emphasizing Basic Radiological Services, is crucial for expanding access.
    • Decentralizing X-ray facilities to be closer to populations is essential for achieving adequate coverage.
