Fig. 3From: The effect of high count rates on cardiac perfusion quantification in a simultaneous PET-MR system using a cardiac perfusion phantomSingle reconstructed transaxial slice from a 5-s frame of the decaying phantom over a range of activities and singles rates showing the locations of the 2 fixed defects placed in the myocardial compartment. The defects showed the same spatial extent over all imaged activities. All images are shown with the same window width and levelBack to article page
