Pericoronary-to-Epicardial Fat Attenuation Ratio for Detecting Impaired Myocardial Flow Reserve at Coronary CT Angiography
The pericoronary-to-epicardial adipose tissue attenuation ratio improved diagnostic performance for detecting impaired myocardial flow reserve, as measured by nitrogen 13 ammonia PET, across real-world heterogeneous coronary CT angiography protocols.
