Recurrent Tc Sestamibi Emboli in the Lungs Revealed on Consecutive Rest and Stress Single-Photon Emission Computed Tomography/Computed Tomography Myocardial Perfusion Images.

Many causes of incidental focal uptake on raw data images using myocardial perfusion imaging, including malignant diseases, metastatic processes, benign pathologies, and physiological conditions, have been reported in the literature. However, iatrogenic Tc sestamibi emboli have not yet been reported. Herein, we demonstrated iatrogenic Tc sestamibi embolization on consecutive rest and stressed myocardial perfusion images at different locations.
