Simultaneous 13N-ammonia and gadolinium perfusion using integrated PET-MRI: diagnostic accuracy in coronary microvascular dysfunction
CFR measurements were concordant between MRI and <sup>13</sup>N-ammonia PET. For detecting significant CMD, CFR<sub>MRI</sub> and CFR<sub>PET</sub> demonstrated comparable and high accuracy. Nevertheless, MRI measurements of rest and stress MBF showed only poor to modest agreement to those obtained with <sup>13</sup>N-ammonia PET. Therefore, although quantitative MRI has clinical utility, further refinements are still required.
