摘要
目的:探讨超声-正电子发射断层扫描(US-PET)融合虚拟导航技术在超声引导淋巴结穿刺活检中的诊断价值。方法:选取2020年8月至2022年8月在湘潭市中心医院行经皮浅表淋巴结穿刺活检术的124例淋巴结肿大患者,将其中采用常规超声引导穿刺的患者纳入超声引导穿刺组(68例),将采用US-PET融合虚拟导航技术引导穿刺的患者纳入US-PET融合引导穿刺组(56例),比较两组患者治疗中取材满意率、重复穿刺率。将穿刺活检结果与临床最终诊断结果进行对比,分析两组诊断准确情况。结果:US-PET融合引导穿刺组患者均顺利完成超声图像与PET融合,图像融合平均时间(9.35±0.42)min,且患者全部取材均符合病理学诊断要求,重复穿刺率为0,低于常规超声引导穿刺组,差异有统计学意义(χ^(2)=6.147,P<0.05)。以临床最终诊断结果为“金标准”,超声引导穿刺组发现良性病变13例,恶性病变55例,准确率83.82%,灵敏度和特异度分别为69.23%和87.27%;US-PET融合引导穿刺组发现良性病变6例,恶性病变50例,准确率、灵敏度和特异度均为100%;两组灵敏度、特异度比较差异有统计学意义(χ^(2)=20.810、7.993,P<0.001)。结论:US-PET融合虚拟导航技术引导淋巴结穿刺活检,有利于精确定位,减少重复穿刺,取材效果满意,活检准确性高,具有临床诊断价值。
Objective:To investigate the application value of ultrasound-positron emission tomography(US-PET)scan fusing with virtual navigation technique in ultrasound-guided lymph node biopsy.Methods:A total of 124 patients with lymph node enlargement who underwent percutaneous superficial lymph node biopsy in Xiangtan Central Hospital from August,2020 to August,2022 were selected as the research objects.Among them,the patients who received conventional ultrasound-guided puncture were included in the ultrasound-guided puncture group(68 patients),and the patients,who adopted the US-PET fusing with virtual navigation technique to guide puncture,were included in the US-PET fusion-guided puncture group(56 patients).The satisfaction rate of obtaining material and the rate of repetitive puncture between the two groups were compared.The results of needle biopsy were compared with the finally clinical diagnosis,and the accuracy of the diagnosis between the two groups was further analyzed.Results:All patients of US-PET fusion-guided puncture group successfully completed fusion of ultrasound image and PET,and the average time of image fusion was(9.35±0.42)min,and the all materials-obtained of patients met the requirements of pathological diagnosis,and the rate of repetitive puncture was 0.00%,which was significantly lower than that of the conventionally ultrasound-guided puncture group,and the difference was statistically significant(χ^(2)=6.147,P<0.05).Based on the clinically final diagnosis,13 cases of benign lesions and 55 cases of malignant lesions were found in the ultrasound-guided puncture group,with an accuracy rate of 83.82%.The sensitivity and specificity of that were 69.23%and 87.27%,respectively.The 6 cases of benign lesions and 50 cases of malignant lesions were found in the US-PET fusion-guided puncture group,with accuracy,sensitivity and specificity of 100%.There were statistically significant differences in sensitivity and specificity between the two groups(χ^(2)=20.810,7.993,P<0.001).Conclusion:The lymph node bio
