Visualization of the whole right atrium wall with Tc-99m Sestamibi scintigraphy.

The article focuses on the case of a 45-year-old woman who was referred for Tc-99m sestimabi scintigraphy due to angina, palpitations, and septal aneurysm diagnosis on echocardiography. A lower mediastinum abnormal activity-associated normal uptake in the myocardium was shown using single photon emission computerized tomography.
