Abstract:
Objective:To explore the application value of Superb microvascular imaging(SMI)technique in diagnosing diffuse thyroid disease with thyroid nodules,and the assessment for treatment efficacy.Methods:A total of 100 patients with diffuse thyroid disease with thyroid nodules(132 nodules),who were treated at the Baoji Hospital Affiliated to Xi'an Medical University from March 2020 to November 2024,were selected.The dual examination of SMI and conventional Color Doppler Flow Imaging(CDFI)were conducted on them.The nature of the nodules was confirmed by pathological examination.The diagnostic sensitivity,specificity and predictive value of SMI and CDFI were analyzed by using the receiver operating characteristic(ROC)curve.A series of conventional indicators,including blood flow volume,blood flow velocity,pattern of blood flow distribution,and vascular morphology,between the two imaging techniques were compared and analyzed.Results:In the 132 thyroid nodules that were detected by pathological examination,SMI identified 94 benign lesions(71.21%)and 38 malignant lesions(28.79%).The sensitivity and specificity of SMI were respectively 94.68%and 89.47%in diagnosing diffuse thyroid disease with thyroid nodules,both of them were higher than those(84.05%and 78.95%)of CDFI,and the sensitivity of SMI diagnosis was significantly higher than that of CDFI diagnosis,and the difference was statistically significant(x2=5.595,P<0.05).The nodule size as SMI diagnosis was(14.62±2.36)mm,which was significantly smaller than(16.35±4.45)mm as CDFI diagnosis,and the difference was statistically significant(x2=3.330,P<0.05).Blood flow velocity and blood flow volume of SMI diagnosis were significantly higher than those of CDFI diagnosis,and the differences were statistically significant(t=5.718,6.567,P<0.05).The detection rates of blood flow distribution mode and vascular morphology of SMI mode were significantly higher than those of CDFI mode,and the differences were statistically significant(x2=9.192,4.776,P<0.05).However,there were not statistically significant differences were observed between the two imaging techniques in terms of the shape,echo type and internal calcification of nodules(P>0.05).Conclusion:SMI technique has a significant advantage in diagnosis and assessment for diffuse thyroid disease with thyroid nodules.It can more accurately assess the hemodynamic changes of the nodules,and provide more reliable diagnostic information for clinical treatment.
