微血管成像技术在甲状腺微小乳头状癌诊断中的应用

目的探讨微血管成像(microvascular imaging,Micro V)技术在甲状腺微小乳头状癌(papillary thyroid microcarcinoma,PTMC)中的应用价值。方法回顾性分析经超声检出并经手术病理证实的PTMC患者60例,共79个病灶,这些病灶均应用彩色多普勒(color Doppler flow imaging,CDFI)技术及Micro V技术观察病灶的血流分布情况,比较两种技术在病灶血管分型及探测病灶内穿支血管的差异,并分析Micro V技术在诊断甲状腺微小乳头状癌中价值。结果在评估甲状腺微小乳头状癌病灶内血流分型方面,Micro V成像与CDFI技术间差异有统计学意义(χ^2=34.000,P<0.05),Micro V成像技术对Ⅲ型血流的显示率明显高于CDFI技术,两者间差异有统计学意义(χ^2=13.388,P<0.05),Micro V成像检测出穿支血管的数量明显高于CDFI技术,两者间差异有统计学意义(χ^2=7.138,P<0.05)。结论Micro V技术在甲状腺微小乳头状癌血流显示方面优于CDFI技术,在甲状腺微小乳头状癌的诊断中有较高的应用价值。

The value of microvascular imaging in the evaluation of papillary thyroid micarcinoma

Objective To investigate the value of microvascular imaging(Micro V)in the evaluation of papillary thyroid micarcinoma(PTMC).Methods Sixty patients with PTMC confirmed by postoperative patholoty were retrospectively analyzed for a total of 79 lesions.The blood flow distribution of these lesions was observed by color Doppler flow imaging(CDFI)and Micro V techniques.The differences between the two technologies in the vascular classification of the lesion and the detection of perforating vessels in the lesion were compared,and the value of Micro V technology in the diagnosis of thyroid micro-papillary carcinoma was analyzed.Results There was a statistically significant difference between Micro V imaging and CDFI in the assessment of blood flow typing in thyroid papillary carcinoma lesions(χ^2=34.000,P<0.05).There was statistically significant difference in the Type ofⅢblood flow display rates between Micro V and CDFI(χ^2=13.388,P<0.05)and Micro V was obviously higher than of CDFI technology.There was statistically significant difference in detection of perforating vessels in the lesion between Micro V and CDFI(χ^2=7.138,P<0.05)and Micro V was obviously higher than of CDFI technology.Conclusion Micro V is superior to CDFI technology in blood flow display of?papillary thyroid micarcinoma and has high application value in the diagnosis of papillary thyroid micarcinoma.
