The study described here was aimed at ascertaining the utility of micro-flow imaging (MFI) during ultrasound (US)-guided microwave ablation (MWA) of thyroid nodules by contrasting its effectiveness with that of contrast-enhanced ultrasound (CEUS).
Seventy-three patients with eighty-eight thyroid nodules who underwent US-guided MWA were included in our study from January 2020 to June 2023. Thirty-five patients underwent CEUS during the MWA process, and thirty-eight patients underwent MFI during the MWA process. We compared the two groups' baseline characteristics, tumor volume (V), volume reduction rate (VRR), complications and clinical characteristics.
Both groups exhibited similar outcomes with respect to V and VRR at 1, 3, 6, 12 and 18 mo after MWA (p > 0.05). Consistency was observed with respect to post-operative complications, supplementary ablation times and surgical duration (p > 0.05). It is worth noting that the MFI group had lower treatment costs compared with the CEUS group (11,337.64 ± 80.93 yuan for the MFI group versus 12,971.23 ± 254.89 yuan for the CEUS group, p < 0.05).
In the MWA procedure for thyroid nodules, MFI is similar to CEUS with respect to safety and efficacy. Simultaneously, it offers the advantage of reducing surgical expenses, which lessens the economic burden for patients.
本研究旨在通过对比微流成像（MFI）与超声造影（CEUS）在超声引导下微波消融（MWA）甲状腺结节中的效果，确定 MFI 在 MWA 中的应用价值。
2020 年 1 月至 2023 年 6 月，我们对 73 例 88 个甲状腺结节患者进行了超声引导下 MWA 治疗，其中 35 例患者在 MWA 过程中进行了 CEUS，38 例患者在 MWA 过程中进行了 MFI。比较两组患者的基线特征、肿瘤体积（V）、体积减少率（VRR）、并发症及临床特征。
两组患者在 MWA 后 1、3、6、12、18 个月的 V 和 VRR 差异均无统计学意义（p > 0.05）。两组患者术后并发症、补充消融次数和手术时间差异均无统计学意义（p > 0.05）。值得注意的是，MFI 组的治疗费用低于 CEUS 组（MFI 组 11337.64 ± 80.93 元，CEUS 组 12971.23 ± 254.89 元，p < 0.05）。
在甲状腺结节的 MWA 治疗中，MFI 与 CEUS 具有相似的安全性和疗效。同时，MFI 可降低手术费用，减轻患者的经济负担。
