Objective To explore the application value and applying rules of local spot compression technique in mammography.Methods 156 patients with suspicious lesions examined through mammography were tested by using local spot compression photography.The diagnosis results of mammography combined with local spot compression photography were analyzed and compared with the pathological results.The radiation dose of mammography combined with local spot compression photography was also compared with that of mammography.Results The sensitivity and specificity of mammography were 85.3% and 79.5% while those of mammography combined with spot local compression photography were 94.2% and 86.5%.There was no significant difference between the radiation dose of mammography and that of mammography combined with local spot compression photography.Conclusion The detection rate and diagnosis accuracy of mammography for breast diseases can be improved with the local spot compression technique,which is especially suitable for the X-ray examination of small lesions exsit in hidden parts and compact breasts.But we should pay attention to the indications during the using process of the local spot compression technique.
