摘要: 目的：分析VR成像在颈动脉近闭塞(carotid near-occlusion)方面的诊断价值。方法：本研究回顾性分析同时经数字减影血管造影(DSA)检查 + 颈动脉CT血管造影(CTA)检查的59名患者的临床资料。以DSA造影结果作为金标准，分析颈动脉CT血管造影中volume rendering (VR成像)诊断颈动脉近闭塞的准确性。结果：以是否诊断出颈动脉近闭塞为标准，VR成像诊断颈动脉近闭塞的敏感度、特异度、阳性预测值、阴性预测值分别为81.25% (13/16)、97.92% (94/96)、86.67% (13/15)、96.91% (94/97)。结论：VR成像在评估近闭塞方面有较高准确性，其直观特征可以作为颈动脉内膜剥脱术或颈动脉支架置入术有效的术前评估工具。
Abstract: Objective: To analyze the diagnostic value of VR imaging in carotid near occlusion. Methods: The clinical data of 59 patients who underwent digital subtraction angiography (DSA) and carotid CT angiography (CTA) were retrospectively analyzed. The accuracy of volume rendering (VR imaging) in carotid CT angiography in the diagnosis of carotid near occlusion was analyzed with DSA results as the gold standard. Results: The sensitivity, specificity, positive predictive value and negative predictive value of VR imaging in the diagnosis of near carotid artery occlusion were 81.25% (13/16), 97.92% (94/96), 86.67% (13/15) and 96.91% (94/97), respectively, based on whether the diagnosis of near carotid artery occlusion was made. Conclusion: VR imaging has high accuracy in the evaluation of near occlusion, and its intuitive features can be used as an effective preopera-tive evaluation tool for carotid endarterectomy or carotid stent implantation.
