Resting thallium
WebThe resting thallium-201 study with 3 hour delayed imaging showed a fixed defect at the apex, a medium sized defect in the anterior wall which partially redistributed as well as a medium sized area of reverse redistribution in the lateral wall (short axis slices, 45k bytes). The arrows (50k bytes) show the area of reverse redistribution. WebDownload scientific diagram Resting thallium 201 myocardial scan with a focal defect in the Inferior septal ren.
