Stress and Rest Myocardial Tomoscintigraphies Using Mono- or Double-isotope Protocol With a Semiconductor Camera

The purpose is to demonstrate the concordance of diagnostic information obtained with: 1. a conventional examination with 2 distinct recordings on D.SPECT camera after 99mTc-sestamibi injections, the first post-stress and the second at rest, 2 to 3 hours later, and 2. a double isotope examination with a supplementary recording after injection of a little activity of thallium-201 at rest after the first recording and before the second injection of 99mTc-sestamibi for conventional recording at rest, in patients showing abnormalities of myocardial perfusion in stress myocardial tomoscintigraphy.
