In the past few years, we have occasionally observed linear bands in the phase images of gated cardiac blood-pool scans along the interventricular septum region among patients with normal septal motions. Our retrospective study investigated the cause of out-of-phase bands of 12 patients. We documented through review of cines, computer analysis of gated cardiac blood-pool scintigraphy data, and correlation with echocardiograms that this phenomenon was artifact introduced by rotational movements of the heart. It is important for nuclear physicians to recognize this rotational artifact on the phase analysis image in order to avoid the erroneous misdiagnosis of wall motion abnormalities of the septum.
在过去几年中，我们偶尔会在室间隔运动正常的患者的门控心血池扫描相位图像中，在室间隔区域观察到线性条带。我们的回顾性研究调查了12例患者出现异相条带的原因。通过回顾电影、对门控心血池闪烁扫描数据进行计算机分析，并与超声心动图进行对比，我们记录到这种现象是由心脏的旋转运动引入的伪影。核医学医师在相位分析图像上识别这种旋转伪影很重要，以便避免对室间隔壁运动异常的错误误诊。
