为 30° 双边旋转斜孔 (RSH) 准直器断层扫描系统建立了正常定量圆周轮廓限制。一项通过铊 201 心肌闪烁扫描和冠状动脉造影评估 196 名患者的研究评估了该系统在检测节段性冠状动脉疾病方面的价值。根据 20 名健康患者的图像计算轮廓曲线，并用于识别左前降支 (LAD)、右冠状动脉和左回旋支 (LCx) 冠状动脉中的显着冠状动脉疾病（≥70% 直径狭窄）。在一组 86 名患者中，心尖或中平面的异常最适合识别节段性冠状动脉疾病。当在 110 名患者的测试组中前瞻性评估此类异常时，LAD 的敏感性和特异性分别为 79% 和 93%，右侧为 90% 和 90%，LCx 冠状动脉疾病为 83% 和 83%。与平面和断层扫描图像的定性解释相比，定量断层扫描显着提高了 TI-201 成像在检测有或没有既往心肌梗死患者的 LAD、右冠和 LCx 冠状动脉疾病方面的敏感性 (P< .001)。
Normal quantitative circumferential profile limits were established for a 30° bilateral rotating slant-hole (RSH) collimator tomographic system. This system's value in detecting segmental coronary artery disease was assessed in a study evaluating 196 patients by thallium 201 myocardial scintigraphy and coronary arteriography. Profile curves were calculated from images of 20 healthy patients and used to identify significant coronary artery disease (≥70% diameter narrowing) in the left anterior descending (LAD), the right, and the left circumflex (LCx) coronary arteries. In a group of 86 patients, an abnormality on the apical or middle plane optimally identified segmental coronary artery disease. When such abnormalities were prospectively evaluated in a test group of 110 patients, the sensitivity and specificity were 79% and 93% for LAD, 90% and 90% for right, and 83% and 83% for LCx coronary artery disease. Compared with qualitative interpretation of the planar and tomographic images, quantitative tomography significantly improved the sensitivity of TI-201 imaging in detecting LAD, right, and LCx coronary artery disease (P< .001) in patients with or without previous myocardial infarction.
