A Meta-analysis of the value of mammography,ultrasound and MRI in the diagnosis of breast tumors / 实用放射学杂志

ABSTRACT

Objective To investigate the value of mammography (MAM),ultrasound (US)and MRI in the diagnosis of breast tumors using a Meta-analysis.Methods A systematic search of relevant literatures was done from CNKI,CBM,VIP,EMBASE OvidSP,PubMed and The Cochrane Library databases.Some related literatures about MAM,US and MRI in the diagnosis of breast tumors and the quality was evaluated,and the available information was extracted.The Meta-analysis was then performed by a Meta-disc 1.4 software,and a Review Manager 5.3 software was used to calculate the summary receiver operating characteristic curves and the area under the curve.Results The diagnostic effect of the MAM+US+MRI was significantly higher than that of mammography or ultrasound (P <0.05).The MAM study heterogeneity among sources was affected by whether it based on BI-RADS diagnostic criteria,and US study heterogeneity was affected by average age of patients.However,the MRI heterogeneity between studies displayed by regression analysis was not affected by each covariate.The diagnostic sensitivity and specificity were 76% (95%CI0.73-0.79)and 72% (95%CI0.69-0.75)for MAM,85% (95%CI0.82-0.87)and 70% (95%CI0.67-0.73)for US,and 95% (95%CI0.93-0.96)and 72% (95%CI0.69-0.75)for MRI,respectively.And the area under curve (AUC)of summary receiver operating characteristic (SROC)curve was 82.0%,88.5% or 97.4%, respectively.Moreover,the AUC of combined three methods together was 98.3%.Conclusion The value of MAM,US and MRI in diagnosis of breast tumor is higher,and the highest one exists when the combined three methods together are used.
