Intensity map shows the percentage of hospitals reporting availability of interventional radiology (IR) facilities and services according to county and state. Counties shaded in gray did not have any hospitals present in the sample. Counties in white had at least one hospital in the sample, none of which reported owning IR facilities and services. Increasing opacity denotes a higher percentage of hospitals reporting the availability of IR facilities and services. The bar graph presents the percentage of hospitals that reported IR as available by state and/or territory.
