[Abstract]

Along with the rise of living standard, late procreation, usage of contraceptive drug, incidence of breast tumor seemed to obviously step up. The surgical operation combined with neoadjuvant chemotherapy in early stage could obviously raise five-year survival rate, so early diagnosis played an important role. Currently, diagnosis and general investigation of breast cancer mainly depended on imageology, including mammography, near infrared Scanning and ultrasonography. But these methods had various disadvantages, such as the poor discrimination of soft tissue. Magnetic Resonance Imaging (MRI) can display perspicuously the structure of mammary gland with standout soft tissue discrimination perspicuously and harmlessly, so it had already been used to diagnose breast diseases. Nevertheless, the application of MRI in the diagnosis of breast diseases is still in a beginning stage, lack of research on large sample. The recognition of MRI feature about breast diseases was deficient. In this research 71 cases with breast tumor underwent MRI scan, including SE sequence, diffusion-weighted imaging and dynamic Contrast-enhanced MRI since 2006. We Compared MRI appearances with mammography, near infrared Scanning, ultrasonography and pathology, Summarized MRI characteristics of breast lesions especially of breast tumors, and evaluated the value of MRI to discriminate local recurrence from postoperative scar after breast conservation therapy.Experiment?Application of the routine MRI and DWI in breast cancerObjective: To investigate the characteristic of routine MRI and DWI of the breast tumor. Methods: Scanned 55 patients suffered breast tumor with routine MRI and DWI using Magnetom trio# tim 3.0T MRI manufactured by Siemens. Analyzed the results of the MRI of the breast tumor along with the results of other examination including mammography, near infrared scanning and ultrasonography and pathology. Results: 55 patients had 37 malignant and 18 benign lesions. Breast cancer showed as irregular?shaped masses nodes without identified border and with uneven low T1 signal and uneven high T2 signal. Benign breast tumor appeared as round mass with smooth border with even low T1 signal and even high T2 signal. The ADC value of breast cancer, benign breast signal and normal breast gland is (1.02?0.17)?10-3(mm2/s), (1.78?0.24)?10-3(mm2/s),(1.97?0.26)?10-3(mm2/s) respectively. The ADC value of breast cancer is lower than that of benign tumor and normal breast gland(p
