| 目的 探讨超微血管成像技术（SMI）和超声造影(CEUS）诊断颈动脉粥样硬化斑块内新生血管的不同价值。方法 我院接诊的64例患者（99个颈动脉粥样硬化斑块），分别行SMI和CEUS检查，比较SMI和CEUS显示颈动脉斑块内新生血管的阳性率和位置差异，及两法诊断斑块内新生血管的一致性。结果 99个颈动脉斑块，CEUS新生血管检出率（79.80%）明显高于SMI（53.54%），SMI和CEUS检测新生血管具有中度一致性（K=0.464，P=0.000）。SMI和CEUS检出新生血管的位置分布区域存在差异，SMI血流成像更易显示位于顶部的新生血管，CEUS更易显示位于基底部的新生血管。结论 SMI与CEUS诊断斑块内新生血管各有优势，CEUS敏感性高，易显示斑块基底部新生血管，SMI与CEUS诊断斑块内新生血管具有中等一致性，两者结合使用才能提供更为准确的斑块易损信息。 |

| Abstract: |
| To explore the different value of SMI and CEUS in the diagnosis of neovascularization in carotid atherosclerotic plaque. Methods Sixty-four patients (99 carotid atherosclerotic plaques) admitted to our hospital underwent SMI and CEUS, respectively. SMI and CEUS showed positive rate and position difference of neovascularization in carotid plaque, and two methods were diagnosed. Consistency of neovascularization within the plaque. Results 99 carotid plaques, CEUS neovascularization rate (79.80%) was significantly higher than SMI (53.54%), SMI and CEUS detection of neovascularization with moderate consistency (K = 0.464, P = 0.000). There are differences in the location distribution of new blood vessels detected by SMI and CEUS. SMI blood flow imaging is more likely to show neovascularization at the top, and CEUS is more likely to display neovascularization at the base. Conclusion SMI and CEUS have advantages in diagnosing neovascularization in plaques. CEUS has high sensitivity and is easy to display neovascularization at the base of plaque. SMI and CEUS have a moderate consistency in the diagnosis of neovascularization in the plaque, and the combination of the two can provide more accurate plaque vulnerability information. |
