  • The post-stress images in the VLA view (top row) shows mild to moderate photopenia of the apex, infero-apical and distal inferior wall and severe photopenia of the basilar half of the inferior wall. This is best seen in the 10th frame.In comparison, the resting images reveal near complete reversibility within the inferior wall with mild persistent apical photopenia.
  • The 10th frame of the post-stress SA view (fifth row of images) shows severe photopenia of the posterolateral wall with near complete reversibilty in the resting phase (last row).
  • Thus, the study demonstrates reversible photopenia or ischemia of the inferior and posterolateral wall. There is also a mild area of fixed apical photopenia. One would expect to find disease within the circumflex artery (which was not grafted) PLUS the saphenous vein graft to the RCA (or the RCA diatal to the anastamosis).
  • The bulls-eye reconstructed images and the 2.5 standard deviation blackout plots, shown below, confirms the above findings.
