| 目的 探讨超微血管成像（SMI）评价甲状腺结节激光消融疗效的价值。方法 选取46例甲状腺结节患者（共56个结节），进行激光消融治疗。分别采用二维超声、CEUS及SMI检查测量消融灶体积，采用CEUS及SMI判断有无未完全消融结节和二维超声低回声区边缘是否存在残余微血管，并进行统计学分析。结果 CEUS检出未完全消融结节11个（11/56，19.64%），SMI检出未完全消融结节9个（9/56，16.07%），差异无统计学意义（P=0.50）。二维超声、CEUS及SMI测量消融灶体积分别为（2.10±2.13）cm3、（1.75±1.67）cm3和（1.79±1.80）cm3，二维超声测量消融灶的体积大于CEUS及SMI（P均<0.05），CEUS测量消融灶的体积与SMI差异无统计学意义（P=0.554）。SMI与CEUS对消融后二维超声低回声区边缘存在残余微血管的检出率差异无统计学意义（P=0.125）。20个单点消融患者中，CEUS及SMI测量消融灶长度、宽度与消融能量均呈线性正相关（r=0.82、0.78，0.80、0.80，P均<0.05）。结论 SMI对未完全消融结节的检出率及对消融灶大小的评估与CEUS具有较好的一致性。 |

| Objective To explore superb microvascular imaging (SMI) in evaluation of curative effect of thyroid nodules after laser ablation. Methods Totally 46 thyroid nodules patients with 56 nodules were collected, and ultrasound guided laser ablation was performed. Two-dimensional ultrasonography, CEUS and SMI were used to detect ablation zone volume respectively. CEUS and SMI were respectively used to detect if there were residual microvessels at the margin of two-dimensional ultrasonography low echo area. Statistical analysis was performed. Results Eleven uncompletely ablation nodules (11/56, 19.64%) were detected by CEUS, and nine uncompletely ablation nodules (9/56, 16.07%) were detected by SMI, which had no statistical significance (P=0.50). Ablation zone volume was measured by two-dimensional ultrasonography, CEUS and SMI were (2.10±2.13)cm3, (1.75±1.67)cm3 and (1.79±1.80)cm3 respectively. Ablation zone volume measured by two-dimensional ultrasonography was bigger than that of CEUS and SMI (all P<0.05). There was no statistical difference of ablation zone volume measured by CEUS and SMI(P=0.554). There was no statistical difference of detection rate of residual microvessels at the margin of two-dimensional ultrasonography low echo area detected by CEUS and SMI (P=0.125). Length and width of the ablation zone measured by CEUS and SMI in 20 single needle ablation cases all had linear positive correlation with ablation energy (r=0.82, 0.78; 0.80, 0.80; all P<0.05). Conclusion SMI has good uniformity with CEUS in the detection rate of uncompletely ablation nodule and the size assessment of ablation lesion. |
