靶心技术将来自单光子发射计算机断层扫描201 TI图像的三维信息合成为二维，以便可以将患者的数据与正常文件进行定量比较。为了表征正常数据库并澄清男性和女性之间的差异，使用临床数据和运动心电图来识别冠状动脉疾病概率小于5%的50名男性和50名女性。结果表明，在应力和延迟的201 TI分布的不均匀性：间隔侧壁计数比小于1.0的女性和男性;前下壁计数比大于1.0的男性，但约等于1.0的女性。在相同的峰值运动心率和收缩压下，女性的洗脱率比男性快，尽管运动时间较短。这些重要的差异表明，单光子发射计算机断层扫描201 TI图像的定量分析需要性别匹配的正常文件。
The bull's-eye technique synthesizes three-dimensional information from single photon emission computed tomographic 201TI images into two dimensions so that a patient's data can be compared quantitatively against a normal file. To characterize the normal database and to clarify differences between males and females, clinical data and exercise electrocardiography were used to identify 50 males and 50 females with less than 5% probability of coronary artery disease. Results show inhomogeneity of the 201TI distributions at stress and delay: septal to lateral wall count ratios are less than 1.0 in both females and males; anterior to inferior wall count ratios are greater than 1.0 in males but are approximately equal to 1.0 in females. Washout rate is faster in females than males at the same peak exercise heart rate and systolic blood pressure, despite lower exercise time. These important differences suggest that quantitative analysis of single photon emission computed tomographic 201TI images requires gender-matched normal files.
