A right atrial myxoma was identified in two patients with radio-angiocardiography-99m Tc. Tumor is identified as a persistent photon-deficient region in both first-pass and equilibrium images. In addition there is an abnormal accumulation and sluggish disappearance of the radionuclide from the right atrium. Even though sensitivity of the procedure should be confirmed, it is a helpful non-invasive technique of great value in the diagnosis oF right atrial tumors.
