对25名患者进行了76项铊-201心肌灌注研究，以评估其可重复性和不同运动水平对成像结果的影响。每名患者在休息时进行了铊-201研究。14例患者在最大运动量下进行了两次研究，12例患者在光照和最大运动量下进行了研究。在14名患者的70个节段中，在两个最大运动试验中的每一个上进行评估，64个（91%）是可重复的。在轻度运动研究中，在两个运动水平下评估的12名患者中，仅53%（16/30）的缺血性缺陷出现在最大运动量下。灌注缺损与动脉造影证实的显著冠状动脉狭窄的相关性对于左前降支和右冠状动脉是好的，但对于回旋支疾病则不好。在最大运动量下的铊-201心肌显像在可接受的范围内是可重复的，但要进行有效的比较研究，必须仔细注意运动技术。
Seventy-six thallium-201 myocardial perfusion studies were performed on twenty-five patients to assess their reproducibility and the effect of varying the level of exercise on the results of imaging. Each patient had a thallium-201 study at rest. Fourteen patients had studies on two occasions at maximum exercise, and twelve patients had studies both at light and at maximum exercise. Of 70 segments in the 14 patients assessed on each of two maximum exercise tests, 64 (91%) were reproducible. Only 53% (16/30) of the ischemic defects present at maximum exercise were seen in the light exercise study in the 12 patients assessed at two levels of exercise. Correlation of perfusion defects with arteriographically proven significant coronary stenosis was good for the left anterior descending and right coronary arteries, but not as good for circumflex artery disease. Thallium-201 myocardial imaging at maximum exercise is reproducible within acceptable limits, but careful attention to exercise technique is essential for valid comparative studies.
