Abstract
Objective To observe the value of ultrasonic elastography in qualitative diagnosis of breast cancer.MethodsTotally 243breast lesions in 230female patients before surgical operation or pathological biopsy were examined with twodimensional gray scale ultrasound and color Doppler flowing imaging(CDFI),and then graded according to breast imagingreporting and data system standard.Then ultrasonic elastography was performed,and the tumors were graded using 5-score evaluating method.Taking pathological findings as gold standards,the accuracy of ultrasonic elastography and conventional ultrasound were compared.Results The sensitivity,specificity,accuracy of ultrasonic elastography was 93.85%(122/130),94.69%(107/113),94.24%(229/243),of conventional ultrasound was 92.31%(120/130),86.72%(98/ 113),89.71%(218/243),respectively.The accuracy of ultrasonic elastography was higher than that of conventional ultrasound(χ2=4.17,P0.05).Conclusion The accuracy of ultrasonic elastography is higher than that of conventional ultrasound.Ultrasonic elastography has important value in diagnosis and differential diagnosis of breast cancer.
