Multigated equilibrium radionuclide angiocardiography: improved detection of left ventricular wall motion abnormalities and aneurysms by the addition of the left lateral view.

Abstract

The usefulness of adding the left lateral (LLAT) view to the standard anterior and left anterior oblique views in multigated equilibrium radionuclide angiocardiography was assessed in 50 patients. Contrast ventriculography was used as the standard. Receiver operating characteristic (ROC) curve analysis was used to assess results. Recognition of inferior wall motion abnormality and left ventricular aneurysms was improved significantly by the addition of the LLAT view. Sensitivity was improved for inferior wall motion abnormality and for aneurysms; there was no loss of specificity. There was no improvement in recognition of anterior wall and apical regional abnormalities in the absence of aneurysms.
