目的比较声触诊成像定量技术(VTIQ)与声触诊定量技术(VTQ)鉴别乳腺良恶性肿瘤的价值。方法随机选择经病理证实的104例患者,共120枚乳腺肿瘤作为研究对象。120枚乳腺肿瘤中包括43枚恶性肿瘤和77枚良性肿瘤。分别在VTIQ及VTQ模式下测量肿瘤内部多组横向剪切波速度(SWV),比较两者的诊断效能。结果 VTIQ测量成功率达100%,而VTQ成功率84%(P<0.05)。VTIQ测量乳腺良性、恶性肿瘤SWV平均值分别为(3.73±1.02)m/s和(5.76±1.11)m/s;VTQ测量乳腺良性、恶性肿瘤SWV平均值分别为(3.84±0.68)m/s和(5.03±0.92)m/s。两种技术所测乳腺恶性肿瘤SWV值均明显高于乳腺良性肿瘤(P<0.01)。若VTIQ和VTQ诊断阈值分别取4.34m/s和4.05m/s时,诊断效能最佳,其诊断恶性肿瘤的灵敏度、特异度及符合率分别为91.7%、85.7%和87.1%;83.3%、72.7%和75.2%。其中,VTIQ特异度及符合率高于VTQ(P<0.05)。结论 VTIQ诊断乳腺良恶性肿瘤优于VTQ。
Objective To compare the value of acoustic palpation imaging (VTIQ) and acoustic palpation (VTQ) in the identification of benign and malignant breast tumors. Methods A total of 120 breast tumors were randomly selected from 104 patients confirmed by pathology. Of the 120 breast tumors, 43 were malignant and 77 were benign. Multiple groups of transverse shear wave velocity (SWV) in the tumor were measured in VTIQ and VTQ modes, respectively, and their diagnostic efficacy was compared. Results The success rate of VTIQ measurement was 100%, while the success rate of VTQ was 84% (P <0.05). The average SWV of benign and malignant tumors was (3.73 ± 1.02) m / s and (5.76 ± 1.11) m / s, respectively. The mean value of VTV for measuring benign and malignant tumors was (3.84 ± 0.68) m / s And (5.03 ± 0.92) m / s, respectively. The SWV values of malignant breast tumors measured by both techniques were significantly higher than those of benign breast tumors (P <0.01). The sensitivity, specificity and coincidence rate of the diagnosis of malignant tumors were 91.7%, 85.7% and 87.1% respectively when the diagnostic threshold of VTIQ and VTQ was 4.34m / s and 4.05m / 72.7% and 75.2%. Among them, VTIQ specificity and compliance rate was higher than VTQ (P <0.05). Conclusion VTIQ is superior to VTQ in the diagnosis of benign and malignant breast tumors.
