Abstract:

Objective     To compare values of the area ratio and the Itoh scoring system with sonoelastography in the diagnosis of breast lesions. Methods       Forty-eight patients with 56 lesions were included in the study. The lesions were scored with the Itoh scoring system. By the area ratio measurement equipped with the ultrasonic machine, the area ratio of the lesion was calculated, with 1.1 being the cut-off point of benign and malignant lesions. According to pathological diagnosis, diagnostic performances of the 2 methods were evaluated with the Chi-square test. Results     The accuracy was 87.5% for the area ratio, 82.1% for the Itoh scoring system, and 92.8% for combined imaging. The diagnostic performance of the area ratio was similar to the Itoh scoring system (P>0.05). Conclusion      Area ratio with sonoelastography is helpful in the differential diagnosis of breast lesions. When area ratio and the Itoh scoring system are combined, the diagnostic accuracy of breast lesions is improved.
