Breast cancer is one of the most common malignant tumor in women, At present, there are different ways in clinical diagnosis of breast cancer,Imaging test is the important way for early detection of breast cancer, CT, MRI examination requirements as a result of equipment, inspection is very expensive ,application is not yet universal.It is not easy for Molybdenum target X-ray to examin of the breast mass benign calcification and malignant calcification ,to locate relatively accurate, the test leads to a higher rate of missing. Because of accurate positioning, high resolution, easy to operate, no pain, non-radioactive, low-cost, Therefore, ultrasonography has become the one of the best methods of imaging for early detection of breast cancer,.This study used two-dimensional ultrasound to display lesion location, size, shape, edge, envelope, internal echo, echo the rear, Microcalcification. Three-dimensional ultrasound contain all the information of two-dimensional ultrasound imaging, at the same time providing an intuitive three-dimensional image of the image, for superficial organs such as eye disease, thyroid, breast qualitative and quantitative positioning to provide an important basis for diagnosis.Objective: Explore the two-dimensional ultrasound, three-dimensional ultrasound in the role of diagnosis of breast masses --compared with the pathological results , Explore the practical value of two kinds of methods in diagnosis of breast masses .Methods: Breast examination revealed 70 cases of patients with breast masses were lines of two-dimensional ultrasound, three-dimensional ultrasound examination, all cases were confirmed by biopsy or surgical pathology. Ultrasonography using color iu22 Philips ultrasound device, high-frequency linear array probe, the probe frequency of 12MHz. using three-dimensional ultrasound to select tumor area, at the same time start the PD key 3Dkey, access vector, cross, crown of the images in three different directions, for image storage. The images will be stored out of choosing the best direction to observe three-dimensional reconstruction imaging.Ultrasonography in patients with supine position from fully exposed bilateral breast scanning with the probe directly and with bilateral contrast, if necessary, to take seat. If the activities of large breast mass can be fixed by hand and then scanning, observation of tumor size, shape, location, echo, whether or not coated, with or without rear side sound attenuation and shadow, and whether the probe pressure to change the attention to form, and then color Doppler flow imaging to observe the availability of internal and peripheral blood flow and distribution.Results: 70 cases of patients with pathological diagnosis of 36 cases are malignant, 34 cases are benign. CDFI and Two-dimensional ultrasound diagnosis : 38 cases are malignant, 32 cases are benign. Three-dimensional ultrasound diagnosis : 34 cases are malignant, 36 cases are benign. the difference of the two kinds of methods was not significant, two-dimensional ultrasound, three-dimensional ultrasound in the diagnosis of benign and malignant tumor on the audio-visual difference was significant.Conclusions: the difference of Two-dimensional ultrasound in identifying benign and malignant masses was significant, and because of sensitivity, specificity and accuracy, lower false positive and false-negative, three-dimensional ultrasound have a high clinical value in identifying the malignant.and benign breast masses,...
