Phase and Amplitude Imaging in the Diagnosis of Acute Right Ventricular Damage in Inferior Infarction

摘要

Right ventricular infarction is not uncommon in patients with inferior myocardial infarcts. Phase and amplitude analysis of equilibrium gated cardiac blood pool studies is useful in documenting right ventricular damage complicating left ventricular infarction. In 15 of 37 patients with acute inferior infarction, right ventricular extension of the infarct was demonstrated by this approach, complementing the findings of infarct avid imaging with Tc-99m pyrophosphate (Tc-99m PYP).
