The availability of plastic microspheres labeled with different-emitting isotopes has allowed
the quantification of blood flow in different organs, including the heart (1). In the past 3 …

Microsphere technique is the reference for assessment of pulmonary blood flow (PBF) but is
destructive; PET, however, can determine PBF noninvasively. Comparisons of these 2 …

Dynamic 1-11C-acetate PET (AC-PET) allows quantification of myocardial blood flow and
