摘要

心肌灌注成像容易受到成像伪影的影响，这可能限制其临床应用。鉴别真正的灌注缺陷和伪影的一种方法是检查与典型冠状血管解剖结构一致的灌注异常的存在。然而，这种方法可能不适用于有冠状动脉异常的患者。我们报告了一个双LAD患者在MPI上表现出孤立的室间隔壁缺血，类似于LBBB患者通常观察到的伪影。本病例强调了熟悉冠状动脉解剖变化的重要性，如双LAD，以避免误解MPI中观察到的非典型灌注缺陷。

Coronary anatomy matters: Dual LAD presenting as atypical ischemia on myocardial perfusion imaging.

Myocardial perfusion imaging is susceptible to imaging artifacts that may limit its clinical utility. One approach to differentiate true perfusion defects from artifacts involves examining the presence of perfusion abnormalities that align with the typical anatomy of coronary vessels. However, this approach may not be applicable in patients having coronary anomalies. We report a patient with dual LAD exhibiting isolated ischemia of the anteroseptal wall on MPI, resembling artifact typically observed in patients with LBBB. The present case highlights the importance of familiarity with variations in coronary anatomy, like dual LAD, to avoid misinterpretation of atypical perfusion defects observed in MPI.

期刊介绍： Journal of Nuclear Cardiology is the only journal in the world devoted to this dynamic and growing subspecialty. Physicians and technologists value the Journal not only for its peer-reviewed articles, but also for its timely discussions about the current and future role of nuclear cardiology. Original articles address all aspects of nuclear cardiology, including interpretation, diagnosis, imaging equipment, and use of radiopharmaceuticals. As the official publication of the American Society of Nuclear Cardiology, the Journal also brings readers the latest information emerging from the Society''s task forces and publishes guidelines and position papers as they are adopted.
