Which metric indicates hospital imaging capacity per million population in Korea as of 2020?

• A. CT scanners per million
• B. Life expectancy at birth
• C. Infant mortality rate
• D. GDP share of healthcare spending

Answer: (A)

Measuring hospital imaging capacity relative to population relies on a resource-density metric that directly links equipment to people. The number of CT scanners per million people expresses exactly that: how many imaging devices are available for each million residents, standardizing for population size so you can compare across countries or over time. Other indicators describe health outcomes or economic factors rather than equipment availability—life expectancy at birth reflects longevity, infant mortality rate tracks deaths in infancy, and GDP share of healthcare spending shows how much a country invests in health, not how many imaging devices it has. So the metric that indicates hospital imaging capacity per million population is CT scanners per million.
