Abstract

Objectives

Elastography is an adjunctive method used in the evaluation of breast lesions combined with ultrasonography. The goal of this study is to analyse the efficiency of strain elastography and its concordance with pathological results on patients who have sonographically demarcated breast lesions.

Materials and methods

39 female patients with breast lesion were included in this study. Strain elastography technique was applied and lesions were categorized into 5 groups by Tsukuba scoring system, and each lesion was scored. Strain ratio value was measured for each lesion. The collected data was compared with the histopathological results which were taken as gold standard.

Results

The mean age of the patients was calculated as 46±12. 26 of 39 lesions were determined as benign, 13 lesions as malignant. The mean SR of the benign lesions was calculated as 2,02±1,73 and the mean SR of the malignant lesions is calculated as 5,7±4,2 (p<0,002). The threshold value of strain ratio is calculated as 2,36 according to ROC curve. While 20 of the benign lesions’ SR values were below the threshold value, 6 were above. On the other hand, 11 of the malignant lesions’ SR values were above threshold value whereas 2 were under. All benign lesions had an elasticity score representing benignancy. 11 of the malignant lesions had an elasticity score representing malignancy; however, elasticity scores of 2 lesions indicated benignancy.

Conclusion

Strain elastography technique of benign and malignant breast lesions may reduce the necessity of biopsy and lower the costs.
