~(201)铊闪烁显象检测心肌缺血的敏感性较心电图运动试验为强,灌注缺损的发生率较心电图ST段压低为高且出现在心绞痛之前。~(201)铊闪烁显像可鉴别无心绞痛者心电图运动试验是真阳性还是假阳牲。锝标记异腈显像提高了心肌灌注显像的精确性。
The sensitivity of ~ (201) thallium scintigraphy to detect myocardial ischemia was stronger than that of electrocardiogram, and the incidence of perfusion defect was higher than that of ST segment of electrocardiogram and appeared before angina pectoris. ~ (201) thallium scintigraphy to identify non-angina ECG test is true or false positive test. Technetium-labeled isonitrile imaging improves the accuracy of myocardial perfusion imaging.
