title: Artifactual focal accumulation of Tc-99m bone imaging tracer in the chest. Technical note (bone imaging artifact).
abstract: Four patients undergoing routine bone imaging with a Tc-99m bone imaging agent were observed to have multiple focal areas of increased uptake in the lungs. Delayed or repeat examination demonstrated resolution of the areas. The authors conclude that this was an isolated and bizarre case of aggregate formation.
