为探讨右侧卧位对左室下壁心肌衰减校正和心梗诊断的价值，对31名正常者和22名冠心病病人同时进行了仰卧位和右侧卧位的99mTc-MIBI静息心肌显像,病人均作了冠状动脉血管造影。观察正常者在不同体位时下壁形态并通过靶心图计算各区象素计数。判定不同体位对各供血区病变诊断的敏感性和特异性。结果表明，右侧卧位时下壁形态显示较好而且计数明显增高，P<0.05，同时对右冠状动脉病变的敏感性和特异性分别为100%和81.8%,较仰卧位明显提高。结果提示，右侧卧位不仅可使下壁衰减得以校正而且可提高对心梗诊断的准确性。

To evaluate the role of the right lateral (RL) imaging in the attenuation correction of left ventricular inferior wall. The RL imaging were obtained immediately after the supine imaging. The inferior wall configuration and regional myocardial counts were assessed by tomography imaging and quantitative polar map analysis for 31 normal controls and 22 coronary artery disease patients all with coronary arteriography. The results were compared between the two imagings. The sensitivity and specificity of diagnosis were compared by both imagings. Results shown that better configuration and higher inferior myocardial counts per pixel were observed in the RL than in supine imaging (P<0.05). Right CAD sensitivity and specificity of lesions for supine imaging were 90.0% and 63.6%, whereas 100% and 81.8% respectively for RL imaging. The RL imaging can well collect the attenuation of inferior wall and improve diagnostic accuracy the right CAD lesions.
