Why the study?
Does equilibrium radionuclide angiography accurately assess left ventricular segmental wall motion compared to contrast angiography?
Does equilibrium radionuclide angiography accurately assess left ventricular segmental wall motion compared to contrast angiography?
Equilibrium radionuclide angiography using a cine display is highly accurate compared to contrast angiography for assessing left ventricular regional wall motion.
Supports equilibrium radionuclide angiography for LV wall motion assessment; leaves open prospective validation against modern modalities.
The qualitative assessement of left ventricular wall motion using a four-point scale has been compared between left ventricular contrast angiography and equilibrium radionuclide angiography in the 30 degrees right anterior oblique projection. Analysis was carried out for five segments of the left ventricle. Four modes of analysis of equilibrium radionuclide angiography were compared and the reproducibility assessed. Overall accuracy of equilibrium radionuclide angiography compared to contrast angiography was greater than 82% to within one degree of motion. One method using a cine display, averaged 97%. We suggest that equilibrium radionuclide angiography using the cine display is the non-invasive investigation of choice in the screening of patients with suspected regional wall motion abnormalities.
