Abstract |
Purpose: Aspiration scintigraphy is a procedure of nuclear imaging to evaluate aspiration and of quantifying the
amount of aspirate. The ultimate goal of our study is to define the correlation between aspiration and aspiration
pneumonia by aspiration scintigraphy, and this is a preliminary report of its trial. Materials and methods: Ten
patients with positive findings by videofluoroscopy were selected. The patients ingested semi-solid food containing
Tc-99m tin colloid 92.5 MBq (2.5 mCi) and images were acquired immediately after the ingestion and 3 hrs later. A
fraction of aspiration to the ingested was calculated using an equation with a decay correction. Results: Five
patients were interpreted positive by aspiration scintigraphy. Four patients were positive at initial images and the
fractions of aspiration were 0.11%, 0.11%, 0.81%, and 0.11%. The one patient who was shown aspirated at both
images had initial 5.82% and delayed 2.26%. Conclusion: Aspiration scintigraphy enables us to localize the
aspiration at any desired time of the test and to quantify its amount. Follow-up studies are warranted. (Nucl Med
