Evaluation Of The Ultrasound And Mammography For Breast Cancer Diagnosis Of Stratification

Objective:To explore the value of color Doppler ultrasonography and molybdenum target in diagnosis of patients with breast neoplasm which different size and glandular organ texture and patients in different groups of age. Methods:There were 173 patients were examined by color Doppler ultrasonography and molybdenum target, the stratified study were done for patients with breast neoplasm, the results of color Doppler ultrasonography and molybdenum target were compared with Pathology result. The value of color Doppler ultrasonography and molybdenum target in diagnosis of breast neoplasm was explored. Result:There was higher sensitivity and specificity of color Doppler ultrasonography than that of molybdenum target in diagnosis of patients with breast cancer which the groups age of patients less than 45. The molybdenum target examine had higher sensitivity and specificity than that of color Doppler ultrasonography in diagnosis of patients with breast neoplasm which the lesion size smaller than 1.0cm, while color Doppler ultrasonography had higher sensitivity and specificity in that of lesion size bigger than 2.0cm. There was higher sensitivity and specificity of color Doppler ultrasonography than that of molybdenum target in diagnosis of patients with breast cancer which breast texture was compactability, as well as molybdenum target examine had higher sensitivity and specificity which breast texture was cast type. There was a moderate level of agreement between color Doppler ultrasonography and molybdenum target in the diagnosis of breast tumors in the agespecific of<45 grouping,45～55grouping, neoplasms size grouping of 1～2cm,>2cm and breast texture grouping of catiieter type, mixted type (Kappa=0.43,0.45,0.44,0.60,0.4,0.46). There was a low of agreement in the agespecific of>55 grouping, neoplasm size grouping of<1cm and breast texture grouping of dense type, fat type (Kappa=0.33,0.35,0.39,0.33). Conclusion:There was advantage and disadvantage of color Doppler ultrasonography and molybdenum target in diagnosis of breast cancer. With the result of stratified study, it could provid an important evidence for clinician in selecting suitable examine to diagnosis breast neoplasm.
