| 目的 探讨实时三维超声技术(RT-3DU)评价下肢动脉粥样硬化斑块在定性和定量方面的应用价值,并与64层螺旋CT三维重建技术相对比。方法 对70例下肢动脉粥样硬化患者进行实时三维超声以及下肢动脉CT三维重建检查,进行影像学对比分析。结果 RT-3DU以及3D-CTA均可显示斑块的位置、管壁结构和管腔狭窄程度。RT-3DU可明确显示斑块的回声强度及其在血流冲击下的活动度,最大斑块处管腔狭窄率测量结果(86.52±2.30)%与3D-CTA (89.36±1.74)%比较差异无统计学意义(P>0.05),相关性良好(r=0.90, P<0.01);二者在斑块识别以及管腔的狭窄程度判断上一致性较高(Kappa值为0.80,P<0.05)。结论 实时三维超声可较好地定性评价下肢动脉粥样硬化斑块,并具有能定量评价斑块、价廉、无创的独特优势,具有较高的临床应用价值。 |

| Objective To explore the value of real-time three-dimension (RT-3D) ultrasonography in quantitative and qualitative diagnosis of lower-extremity arteriosclerosis obliterans, and to compare RT-3D with 64 multi-slice spiral CT 3D angiography (3D-CTA). Methods Seventy patients with lower-extremity arteriosclerosis obliterans were examined by both RT-3D ultrasonography and 3D-CTA, and the results were analyzed comparatively. Results RT-3D ultrasonography and 3D-CTA displayed clearly the location of atherosclerotic plaques, the structure of vessel wall and the extent of the stenosis. RT-3D ultrasonography showed the echo and the mobility of plaque in the blood vessl. There was a high correlation between RT-3D ultrasonography and 3D-CTA in the rate of stenosis (86.52±2.30)% and (89.36±1.74)%, (r=0.90, P<0.01), while the identification of plaques and the extent of stenosis with RT-3D ultrasonography and 3D-CTA had the better concordance according to the value of Kappa 0.80 (P<0.05). Conclusion RT-3D ultrasonography can evaluate lower-extremity arteriosclerosis obliterans in quality. As a cheap, non-invasive evaluation method, RT-3D ultrasonography is of high clinical value in practice. |
