WebEstablishing a high-resolution non-ECG-gated first-pass perfusion (FPP) cardiac MRI technique may improve accessibility and diagnostic capability of FPP imaging. We propose a non-ECG-gated FPP imaging technique using continuous magnetization-driven golden-angle radial acquisition. The main purpose of this preliminary study is to evaluate ... 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.
