Abstract:
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 (χ2 =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(χ2 =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.
