title: Evaluation of gastro-pulmonary aspiration by a radioactive technique: concise communication.
abstract: Seven selected patients were given 3-5 mCi of Tc-99m sulfur colloid orally at bedtime and the lungs were imaged in the morning. Two showed definite evidence of aspiration and one suggestive evidence. This is a simple, non-invasive method of demonstrating pulmonary aspiration of gastric contents.
