多道门控平衡心血池显像评价下段室壁运动时，传统的前位和45度左前斜位(LAO)是有限的。这项研究通过比较25名患者的核素造影和对比剂脑室造影来评估增加70度的LAO切面，其中17名患者表现出异常的下壁运动。17名患者中只有10名患者在前视下正确地发现了下壁运动异常，而在70度LAO下，17名患者中有16名正确识别出了下壁运动异常。可评估的下节段数从前位的58%提高到70度LAO的98%。当下壁节段在前视面上可见时，可以准确地评估下壁运动。增加70度LAO切面有助于下壁运动异常的多门控平衡核素显像术检测，而特异性损失很小。
Conventional anterior and 45-degree left anierior oblique (LAO) views are limited in the evaluation of inferior segmental wall motion by multiple gated equilibrium cardiac blood pool scintigraphy. This study evaluated the addition of a 70-degree LAO view by comparing scintigraphic and contrast ventriculography in 25 patients, of whom 17 demonstrated abnormal inferior wall motion. Abnormal inferior wall motion was correctly identified in only 10 of 17 patients in the anterior view, but in 16 of 17 patients in the 70-degree LAO view. The number of assessable inferior segments was improved from 58% in the anterior view to 98% in the 70-degree LAO view. When the inferior segments could be visualized in the anterior view, inferior wall motion was accurately assessed. The addition of the 70-degree LAO view aids in the multiple gated equilibrium scintigraphic detection of inferior wall motion abnormalities with a minor loss in specificity.
