摘要

The paper by Hsu et al. (1) in this issue of iJACC presents the results of a validation study on the use of cardiac magnetic resonance (CMR) imaging to map myocardial blood flow (MBF) at the spatial resolution of the underlying images ("pixel-wise"), acquired during the first pass of a gadolinium contrast bolus injection. This work raises 2 interesting questions: do we need pixel-level resolution for mapping MBF, despite the prevalent use of simpler and robust methods, which are exemplified by the bull's-eye plot, well known from nuclear cardiac imaging? And, what is to be gained by mapping, not just the relative distribution of blood flow, but also the absolute MBF in units of milli-liters/minute/gram of tissue? Though the study by Hsu et al. (1) did not try to explicitly address these questions, the longer-term, clinical application, and significance of the reported technique depends on how these questions are answered.
