Technetium-99m stannous pyrophosphate scintiscanning was performed in 22 patients with radiographically detected calcification within the cardiac silhouette. All but one of these scintigrams showed a localised area of increased activity similar to that ordinarily seen in acute myocardial infarction. Scintiscans in 3 patients after removal of the calcified aortic valve reverted to negative. It was concluded that this technique for acute infarct detection may yield false positive results in the presence of cardiac calcification.
对22例在X线片上发现心脏轮廓内有钙化的患者进行了锝-99m焦磷酸亚锡闪烁扫描。除1例闪烁扫描图外，所有这些扫描图均显示出一个局部活性增加区域，类似于急性心肌梗死时通常所见的情况。3例患者在切除钙化主动脉瓣后闪烁扫描结果转为阴性。得出的结论是，这种用于急性梗死检测的技术在存在心脏钙化时可能会产生假阳性结果。
