摘要
伪影是造成心肌灌注显像出现假阳性的主要原因之一,有必要对造成伪影的因素、伪影的表现形式和校正方法进行系统、全面的认识。心肌灌注显像中的伪影主要可归结为与检测仪器有关的伪影,与病人因素有关的伪影,与图像处理有关的伪影,以及与非冠状动脉疾病有关的伪影等。
Artifacts are a significant source of false positive of myocardial perfusion imaging. It is essential to recognize and understand various reasons of artifacts in myocardial perfusion imaging. The main artifacts of SPECT myocardial perfusion imaging include artifacts associated with instrumentation, artifacts caused by patient, artifacts due to image process and artifacts related to non-coronary artery disease.
