COVID-19 vaccine associated myocarditis. Short-axis 1.5T MRI images and ECG findings of a 19-year-old man with myopericarditis who presented with chest pain 3 days following the second dose of an mRNA COVID-19 vaccine (mRNA-1273). Cardiac MRI performed 2 days after symptom onset demonstrates mid wall to subepicardial late gadolinium enhancement (LGE) at the basal to mid inferior lateral wall with adjacent pericardial enhancement (A, red arrow), corresponding hyperintensity on T2-weighted imaging (B, orange

Figure 1: Image shows use of fluorine 18 (18F)–fluorodeoxyglucose (FDG) PET/CT imaging process as assay method for computing and interpreting tumor metabolic activity as pipeline using either one or two or more scan sequences. Standardized uptake values (SUVs) are used to reduce variations caused by differences in patient biodistribution and amount of FDG used. Measure SUVx refers to one of several possible SUV measures such as SUVmax, SUVmean, or SUVpeak, where max, mean, and peak refer to value calculated
