WebFor imaging during first pass, there should be a direct and quantifiable relationship between contrast agent concentration and myocardial perfusion. In both cases, the contrast agent concentration should be … WebNov 9, 2024 · CMR first-pass perfusion can be impaired in both injured and remote myocardium in STEMI patients treated with primary PCI. These findings indicate that CMR first-pass perfusion may be a feasible method to evaluate myocardial injury after STEMI in addition to conventional CMR parameters.

WebSep 25, 2024 · First-pass perfusion cardiac magnetic resonance (FPP-CMR) is becoming an essential non-invasive imaging method for detecting deficits of myocardial blood flow, allowing the assessment of coronary heart disease. Nevertheless, acquisitions suffer from relatively low spatial resolution and limited heart coverage. WebJul 8, 2024 · A: We are using the same protocols for dobutamine stress perfusion as adenosine. Heart rate is often over 120 and then we use 2 concatenations and acquire 2 slices on alternate beats for a total of 4 slices. The cine portion of the dobutamine stress should be performed prior to the perfusion imaging. There are two major classes of contrast agents used for first-pass perfusion imaging. The extravascular, extracellular class of agents were … See more To test new contrast agents and validate new imaging sequences, phantoms and animal models of human cardiovascular disease are often employed. First-pass perfusion imaging of … See more Several artifacts can occur in first-pass perfusion imaging that must be recognized in order to correctly interpret the images qualitatively.
