Objective: Ultrasound diagnosis of breast lumps and pathological diagnosis of comparative analysis , in-depth study on ultrasound imaging diagnosis of breast lumps qualitative and accuracy . Methods: In this paper, a diagnosis of 500 cases of breast lumps preoperative ultrasound imagery and body disease gross specimen images, pathological diagnosis were analyzed retrospectively . Results : 500 cases in 436 cases of benign lesions and malignant lesions of 64 cases . Of which 148 cases of fibroadenomas , duct dilatation in 47 cases, 59 cases of breast cysts , breast cysts plot , 62 cases of breast abscess in 35 cases , intraductal papilloma in 37 cases, other benign tumors in 48 cases, 10 cases of intraductal carcinoma , invasive 49 cases of ductal carcinoma , invasive lobular carcinoma in 5 cases. Conclusions: ( 1 ) ultrasound imaging of the breast lumps positioning accuracy was 100%. Its sonographic morphological analysis and judgment is the most important basis for the positioning of breast lumps . Direct signs include shape, location , orientation , diameter and anteroposterior diameter ratio , contour edges , internal echo , sound absorption characteristics . Indirect signs include proximity to structural distortions , the suspensory ligament is retracted or angled , with or without dilatation , skin, subcutaneous fat and pectoralis major changes. Dynamic observation including compressibility and mass activity . ( 2 ) ultrasound imaging is difficult to distinguish benign breast lesions and precancerous lesions, but by its specific indicators such as spiculation , vicious ring , echo-free zone and the internal mass flow signal to increase breast lumps qualitative accuracy. For common benign breast lesions: breast cysts, fibroadenomas , integrated milk cysts, intraductal tumors, mastitis diagnosis clearly showing its characteristic . ( 3 ) through the first ultrasound imaging pictures, ill gross specimen images and pathological analysis in the form of a control can be clearly demonstrated that ultrasound image positioning, qualitative characteristics , can produce strong visual effect , makes clear . Has a high practical value.
