Abstract:
Objective：To compare the accuracy and cost-effectiveness of full-digital mammography and combined magnetic resonance imaging in the diagnosis of breast ductal carcinoma in situ(DCIS)，so as to provide reference for the selection of early screening schemes for DCIS.Methods：The clinical data of 84 patients with DCIS diagnosed by pathological examination in our hospital from August 2014 to August 2018 were retrospectively analyzed.The preoperative full digital mammography and magnetic resonance imaging(MRI) findings were sorted out.The accuracy of DCIS diagnosed by molybdenum target，magnetic resonance imaging and molybdenum target combined with magnetic resonance imaging was analyzed.Cost/accuracy was used to calculate the correct detection cost of DCIS diagnosed by three modes，i.e.cost-effectiveness.Results：The diagnostic accuracy of DCIS by digital mammography and MRI alone was 77.38% and 85.71%，respectively.The combined diagnostic accuracy of DCIS was 91.67%(77/84).The combined diagnostic accuracy was higher than that by single diagnosis(P<0.05).There was no significant difference between the diagnostic accuracy of DCIS by MRI alone and that by digital mammography alone(P>0.05).The cost-benefit ratio of DCIS diagnosed by full digital mammography was the lowest，followed by MRI，and the cost-benefit ratio of combined diagnosis was the highest，with statistical significance(P<0.05).Conclusion：For most suspected DCIS patients，full digital mammography can meet the needs of early clinical diagnosis，and high-risk patients can consider joint MRI examination.
