Centrilobular micronodules are an image descriptor that refers to centrilobular nodules when the nodules are very small and present in a centrilobular distribution in the lungs. They are usually seen with bronchiolitis and can blend into tree-in-bud opacities.
Postprocessing techniques such as obtaining maximum intensity projections (MIPs) use the original thin-section dataset and help make centrilobular nodules more conspicuous and easier to interpret.
