Excerpt
The concept of equilibrium radionuclide nuclear angiography (ERNA) has come a long way since it was first introduced in the late 1970s as the gated equilibrium blood-pool time activity method where left ventricular ejection fraction (LVEF) could be determined from planar images and soon after also right ventricular ejection fraction (RVEF) from first pass imaging

2 being a new alternative to cardiac catheterization with contrast ventriculography. Non-invasive and radiation free methods for assessment of cardiac function has since then emerged in the shape of MRI, bioelectric impedance, indicator dilution technique and echocardiography along with further development of radioactive tracer techniques such as myocardial perfusion imaging and cardiac CT as a radiographic alternative. This multitude of available methods for determination of cardiac function has inevitably increased the demand for comparative studies in order to evaluate which methods best serve a given patient population in terms of information provided along with accuracy, reproducibility, availability, cost, risk and practicability. One of the emerging modalities is Cadmium Zinc Telluride gated SPECT equilibrium radionuclide angiography (CZT-ERNA).
