A Comparative Study on the Diagnostic Value of Breast Abbreviated MRI for Breast Diseases
Objective To compare the diagnostic value of breast MRI full diagnostic protocol(FDP),first postcontrast subtracted(FAST)and diffusion weighted imaging(DWI)and in breast phymatoid disease,and union FAST-DWI Find out the best solution for MRI of breast disease.Methods A retrospective analysis of 84 patients who underwent full-sequence breast MRI examination with pathological findings was performed by two experienced radiologists,respectively,to evaluate breast MRI-FDP,FAST,DWI and FAST+DWI schemes,and then complete the evaluation reports.If there is any disagreement,it will be completed through consultation between two physicians,with a two-week interval between each protocol.Using pathological results as the gold standard to compare the number of images of each scheme,the time spent on diagnosis,the confidence of diagnosis,and the sensitivity,specificity,positive predictive value,and negative predictive value of diagnosis.Results The time spent and the number of images of two physicians using FDP to evaluate breast disease were significantly greater than those of FAST,DWI and FAST+DWI(P＜0.01),and the time spent and number of images of DWI were less than those of FAST(P＜0.05).The diagnostic confidence of FDP and FAST+DWI had no statistical difference(P＞0.05),both were higher than FAST and DWI(P＜0.01),and the diagnostic confidence of FAST was higher than DWI(P＜0.01).The diagnostic sensitivity,specificity,positive predictive value and negative predictive value of the four protocols were not significantly different.Conclusion The breast FAST+DWI scheme can reduce the scanning time and diagnosis time,improve the work efficiency of radiologists,and can be used for routine screening of female breasts on the basis of ensuring the diagnostic confidence,sensitivity,specificity,positive predictive value and negative predictive value.
