摘　　要：目的对比双能CT血管成像与一般螺旋CT成像在判断眼动脉疾病中的应用价值。方法选择疑为眼缺血综合征需行CT血管成像术(CTA)的患者100例,其中50例行颅脑双能CT血管增强检查(研究组),另50例行一般螺旋CT增强检查(对照组)。结果研究组的颅内段、眶内段及视神经管段的眼动脉直径均显著比对照组大(P<0.05);研究组斑块检出率为36%,较对照组的8%高(P<0.05)。结论双能CT血管成像可更好地显示眼动脉直径与斑块状况,在判断眼动脉疾病中的应用价值较一般螺旋CT成像更胜一筹。Objective The application value of dual energy CT angiography and general spiral CT imaging in the judgment of ophthalmic artery disease. Methods 100 patients with suspected ocular ischemic syndrome underwent CT angiography（CTA）, 50 of which were performed with dual energy CT angiography（Study Group） and 50 patients with normal spiral CT enhancement（control group）. Results In the study group, the diameter of the intracranial segment, the orbital segment and the optic canal segment were significantly larger than those of the control group（P0.05）. The detection rate was 36% in the study group and 8% in the control group（P0.05）. Conclusion Dual energy CT angiography can better display the ophthalmic artery diameter and plaque status, diagnostic value on ophthalmic artery disease with spiral CT imaging is better.
