[Diagnosis of heart failure with radionuclide ventriculography].

Radionuclide ventriculography is presented as noninvasive scintigraphic method to assess the pump function of the heart. Its role in diagnosis and prognosis of congestive heart failure is described. Advantages and limitations of this technique as compared to echocardiography are discussed, and the importance of left-ventricular ejection fraction in the evaluation of congestive heart failure is critically reviewed.
