超声弹性成像硬度评分与面积比对乳腺肿块的诊断价值

The diagnostic value of ultrasound elastography hardne＇s score and area ratio to identity benign and malig-nant lesions

目的：探讨超声弹性成像硬度评分与面积比对乳腺良、恶性肿块鉴别的诊断价值。方法收集接受治疗的乳腺肿块患者90例，采用超声弹性成像技术对患者进行检测，并根据手术病理学诊断结果将其分为恶性组（40例，肿块共45个）与非恶性组（50例，肿块共57个），分析肿块成像硬度评分与面积比值等资料。结果良性肿块超声弹性成像0～2分50个，3～4分7个，恶性肿块0～2分7个，3～4分38个，两组差异有统计学意义（χ^2＝28．55，P ＜0．05）；良性肿块平均面积比值为（1．01±0．27），恶性肿块为（2．28±1．68），两组差异有统计学意义（t ＝9．22，P ＜0．05）；弹性成像硬度评分诊断乳腺恶性肿块灵敏度、特异度、准确率分别为87．72％、84．44％、86．27％，面积比值法分别为85．96％、86．67％、86．27％，两种方法联合诊断乳腺恶性肿块灵敏度、特异度、准确率分别为96．49％、95．55％、96．08％，联合检查具有明显优势，差异有统计学意义（χ^2＝16．24、13．58，均 P ＜0．05）。结论超声弹性成像硬度评分联合面积比值法对鉴别乳腺良恶性肿块具有较高准确率。

Objective To investigate the diagnostic value of ultrasound elastography hardness score and area ratio to identify benign and malignant lesions.Methods 90 patients with breast lumps were selected and divided into the malignant and non -malignant group according to surgical pathology diagnosis,they were 40 cases （a total of 45 tumors）and 50 cases （a total of 57 tumors）,two groups of patients were detected in ultrasound elastography,anal-ysis of imaging hardness ratings and area ratio and other information,to investigate the clinical diagnostic value. Results The ultrasound elastography of 50 cases with benign tumor were 0 -2 point,7 cases were 3 -4 point, 7 cases with malignant tumors were 0 -2 point,38 cases were 3 -4 point,the difference between the two groups were statistically significant （χ^2 =28.55,P 〈0.05）;The average area ratio of benign tumor was （1.01 ±0.27）,malignant tumors was （2.28 ±1.68）,the difference between the two groups was statistically significant（t =9.22,P =0.001）;the sensitivity,specificity,accuracy of elastography hardness rating in diagnosis of malignant breast tumors were 87.72%,84.44%,86.27%,the area ratio method were 85.96%,86.67%,86.27%,joint inspection of the two groups were 96.49%,95.55%,96.08%,joint inspection had obvious advantages,the difference was statistically sig-nificant（χ^2 =16.24,13.58,P 〈0.05）.Conclusion Ultrasound elastography hardness rating combined area ratio has a higher accuracy rate for differentiating benign and malignant breast tumors.
