Chapter 13 / Display and Analysis of SPECT Equilibrium 13913Display and Analysis of SPECTEquilibrium RadionuclideAngiocardiographyAt time of this writing SPECT ERNA is not routinelyperformed in most nuclear cardiology laboratories. Consequently,no standards have been set for display and analysisof SPECT ERNA. It seems reasonable to use a similarapproach for SPECT ERNA as for SPECT myocardial perfusionimaging.The display of ERNA SPECT should include at a minimum:1. Rotating planar projection images.2. Reconstructed static slices.3. Movie display of selected multiple ECG-gated slices: vertical long axis,short axis and horizontal long axis.4. Left ventricular volume curve.Interpretation of SPECT ERNA images should follow a similar systematicapproach and quality control as described for SPECT myocardialperfusion imaging.DISPLAY OF SPECT ERNAStatic reconstructed SPECT slices should be displayed using the sameplanes as for SPECT myocardial perfusion images (Fig. 13-1).MOVIE DISPLAYThe uniqueness of SPECT ERNA is that ECG-gated blood poolmovies can be analyzed at any desired plane in one of three conventionaltomographic cuts (Figs. 13-2, 13-3).
