WebMyocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, your doctor may order this test to find areas of damaged heart muscle. This test may be done during rest and ... WebA myocardial perfusion SPECT (Single Photon Emission Computed Tomography) study, also called a cardiac stress-rest test, helps your doctor evaluate your heart’s blood supply. Two sets of images showing blood flow are obtained: the first following a period of rest, and the second following a period of stress (i.e., exercise). This is how it works:

WebThe planar images (A) show a quantitative heart to contralateral lung (H/CL) ratio of 1.86, which is strongly suggestive of TTR-CA. Diffuse myocardial uptake was confirmed on SPECT (B) including Cardiac SPECT (C) images with a visual semiquantitative score of Grade 3 with myocardial uptake being greater than rib uptake. WebPlanar images may be acquired before the initiation of the SPECT acquisition to evaluate lung radiopharmaceutical uptake (i.e., lung-to-heart activity ratio) and to evaluate the pattern of myocardial perfusion in the event of patient movement during SPECT acquisition. heal and love yourself https://daisyscentscandles.com
