【摘要】：目的探讨超声弹性成像(UE)在乳腺肿瘤诊断中的价值,并与弥散成像(DWI)进行对比分析。方法收集经病理检查证实的160例患者影像资料,共182处病灶,术前均行超声UE及DWI,UE采用5分法诊断,DWI依据所测病灶ADC值诊断,分别与病理检查结果进行比较。结果 UE诊断恶性肿瘤89处,其中,正确诊断恶性肿瘤78处,漏诊7处,良性误诊为恶性11处;诊断良性肿瘤93处,正确诊断86处,漏诊11处,恶性误诊为良性7处,敏感性为87.6%,特异性为92.5%,准确性为93.9%。UE联合DWI诊断恶性肿瘤86处,其中,正确诊断恶性肿瘤81处,漏诊4处,良性误诊为恶性5处;诊断良性肿瘤96处,正确诊断92处,漏诊5处,敏感性为94.1%,特异性为95.8%,准确性为97.2%。结论 UE对乳腺良、恶性肿瘤诊断有较高的敏感性、特异性、准确性,联合DWI检查能明显提高对乳腺肿瘤良、恶性诊断的敏感性、特异性及准确性。
[Abstract]:Objective to evaluate the value of (UE) in the diagnosis of breast neoplasms and compare it with (DWI). Methods the imaging data of 160 patients confirmed by pathological examination were collected. All the lesions were diagnosed by UE and DWI,UE with 5 points before operation. DWI was diagnosed according to the ADC value of the lesions, and the results were compared with those of pathological examination. Results among 89 malignant tumors diagnosed by UE, 78 were correctly diagnosed, 7 were missed, and 11 were misdiagnosed as malignant. Of the 93 benign tumors, 86 were correctly diagnosed, 11 were missed, 7 were misdiagnosed as benign, the sensitivity was 87.6, the specificity was 92.5, and the accuracy was 93.9%.UE combined with DWI in the diagnosis of 86 malignant tumors. 81 malignant tumors were correctly diagnosed, 4 were missed and 5 were misdiagnosed as malignant. 96 benign tumors were diagnosed correctly, 92 were correctly diagnosed, 5 missed diagnoses, the sensitivity was 94.1, the specificity was 95.8and the accuracy was 97.2B. Conclusion UE has high sensitivity, specificity and accuracy in the diagnosis of benign and malignant breast tumors. Combined with DWI, it can improve the sensitivity, specificity and accuracy of diagnosis of benign and malignant breast tumors.
