Nonsegmental ventilation-perfusion scintigraphy mismatch after radiation therapy.


Journal Article

PURPOSE: This report illustrates the utility of ventilation-perfusion scintigraphy in differentiating radiation pneumonitis from other causes of dyspnea, including pulmonary embolism, heart failure, obstructive tumor, and chronic obstructive pulmonary disease. METHODS AND RESULTS: A nonsegmental mismatched perfusion abnormality, which exactly conformed to a radiation port, was diagnostic of radiation pneumonitis. CONCLUSION: In patients with lung tumors presenting with dyspnea, ventilation-perfusion scintigraphy may be useful in diagnosing radiation pneumonitis and effectively excluding other causes of dyspnea.
