Abstract:
ObjectiveTo explore the value of the diagnosis of breast cancer by acoustic elastography, conventional ultrasonography (including gray-scale ultrasonography, color Doppler flow imaging and Doppler spectrum) and mammography.MethodsOne hundred and four patients with breast disease conifrmed by surgical pathology were studied retrospectively in Zibo Maternal and Children Health Hospital. All the patients were examined by acoustic elastography, conventional ultrasonography and mammography before surgery.ResultsPathological results of 104 cases were: sixty-five malignanies and 39 benignities. The most common signs in the diagnosis of breast cancer by conventional ultrasonography were spicule sign (76.9%, 50/65), taller-than-wide sign (73.8%, 48/65), vascular resistance index>0.7 (70.8%, 46/65), calciifcation (53.8%, 35/65). And breast masses without these signs were regarded as benign lesions. The diagnostic criteria of breast cancer by acoustic elastography was 5-point method. We regarded the lesions got more than 3 points as malignancy. The most common signs in the diagnosis of breast cancer by mammography were dense shadow (73.8%, 48/65), spicule sign (70.8%, 46/65), calcification (69.2%, 45/65). And breast masses without these signs were regarded as benign lesions. The diagnostic accuracy of acoustic elastography, conventional ultrasonography, mammography, conventional ultrasound plus acoustic elastography, conventional ultrasound plus mammography and acoustic elastography plus mammography for breast tumor were 88.4% (92/104), 86.5% (90/104), 83.7% (87/104), 93.3% (97/104), 90.4% (94/104) and 89.4% (93/104), respectively. ConclusionsThe combination of any two imaging modalities can improve the diagnostic accuracy of breast cancer. And conventional ultrasound combined with acoustic elastography could be an effective method in the diagnosis of breast cancer.
