Atherosclerotic plaques may not be demonstrated adequately by standard anteroposterior (AP)-lateral projections of carotid arteriography. We evaluated selective carotid arteriography in oblique projections for 60 individual carotid arteries. Two neuroradiologists evaluated arteriograms in four separate sessions devoted to AP-lateral views alone and in combination with oblique projections. The lumen surface was characterized as "smooth," "irregular," or "ulcerated." When oblique projections were added to AP-lateral views, there was a significant shift of radiologic diagnosis from smooth to irregular or ulcerated. Addition of oblique projections to standard AP-lateral views increases the radiographic diagnosis of carotid artery lesions that may be the source of emboli.
标准的颈动脉造影前后位（AP）-侧位投照可能无法充分显示动脉粥样硬化斑块。我们对60条独立的颈动脉进行了斜位选择性颈动脉造影评估。两位神经放射科医生在四个单独的时间段评估血管造影片，其中一个时间段仅专注于AP-侧位视图，另一个时间段则结合斜位投照。管腔表面特征被分为“光滑”“不规则”或“溃疡形成”。当在AP-侧位视图基础上增加斜位投照时，放射学诊断结果从光滑显著转变为不规则或溃疡形成。在标准的AP-侧位视图基础上增加斜位投照可提高对可能为栓子来源的颈动脉病变的影像学诊断。
