The Value of B-CAD Assisted Ultrasonography in Diagnosis of Breast Cancer
Objective: To evaluate the feasibility of diagnosing breast cancer by ultrasound with computer-aided detection system (CAD).
Materials and Methods: A total of 99 patients with 100 lesions were included in this study(mean age, 51years; range, 27-75). Of 100 lesions, 64 breast cancer and 36 benign lesions confirmed by pathology. All patients underwent conventional ultrasound examination and ultrasound examination with B-CAD system in sequence in the same day by two doctors, and accuracy of the diagnosis was calculated and compare the accuracy of B-CAD system in diagnosing the breast cancer of different size.
Results: there was no significant difference in diagnosis accuracy of breast cancer by ultrasound with and without B-CAD system. The diagnosis accuracy of breast cancer increased 44% with B-CAD system when the lesions were less than 1cm in diameter and there was a significant difference compared to conventional ultrasound without B-CAD system(p<0.05). However, there was no significant difference when the lesions were more than 1cm in diameter with and without B-CAD system(p>0.05).
Conclusions: The detection rate of breast cancer can be significantly improved with B-CAD system when the lesion is less than 1cm in diameter.
