Cardiovascular risk according to myocardial uptake pattern of ¹⁸F-FDG-PET/CT. Patients were stratified by normal/abnormal myocardial perfusion imaging (MPI) findings. The Y-axis depicts the percentage of patients with abnormal and normal myocardial perfusion/function, respectively, in each subpopulation of distinct myocardial uptake pattern. The total number of patients within a subpopulation is set as 100%. (A) While focal myocardial ¹⁸F-FDG uptake was predominantly observed in patients with abnormal perfusion and function, patients with no myocardial ¹⁸F-FDG uptake more frequently presented with normal cardiac perfusion/function. (B) Dividing focal and focal on diffuse patterns into subgroups revealed that the focal spot pattern further improved risk prediction for cardiac abnormalities.
