[Evaluation of endobronchial foreign bodies by 99mTc-MAA pulmonary perfusion scintigraphy]

We evaluated the lung perfusion scintigraphic findings of endobronchial foreign bodies in four children. We could detect the bronchial stenosis due to foreign bodies by lung perfusion scintigraphy more easily than plain chest radiograph and predict the location at lobar bronchi level according to the hypoperfusion area. We guessed that the scintigraphic abnormal finding after plain chest radiographic normalization reflect bronchial inflammatory change after foreign body removal and so it is very important to perform the follow up scintigraphic examination.
