Ga-67 scintigraphy can be useful in the diagnosis of myocarditis and, therefore, can affect the management of patients who have severe congestive heart failure. Because biopsy results can be focal, a biopsy may miss areas affected by the myocardiopathic process. In such an instance, Ga-67 imaging can provide valuable information. Obviously, the results of the scan would affect management decisions drastically. Presented here is a case in which the Ga-67 scan at 48 hours showed cardiac blood pool visualization, indicating severe left ventricular dysfunction and secondary renal failure. This became apparent from additional Ga-67 scintigraphic images obtained at 144 hours.
