Abstract :Purpose: The aim of this study was to compare the diagnostic performances of abbreviated protocol insert ignore into journalissuearticles values(AP); magnetic resonance imaging insert ignore into journalissuearticles values(MRI);, AP combined with diffusion-weighted imaging insert ignore into journalissuearticles values(DWI);, and full dynamic protocol insert ignore into journalissuearticles values(FDP); in the differentiation of breast cancers from benign breast diseases. Materials and Methods: The total study population consisted of 68 patients who underwent breast MRI insert ignore into journalissuearticles values(1.5 Tesla); between January 2016 and December 2021 for the evaluation of suspicious findings on mammography or ultrasonography. All lesions were evaluated by 2 radiologists using AP, AP+DWI, and FDP. The reader sensitivity, specificity, and accuracy were analyzed using the “Chi-squared” test. The inter-observer agreement insert ignore into journalissuearticles values(IOA); between the Breast Imaging Reporting and Data System insert ignore into journalissuearticles values(BI-RADS); category assessments of the two readers was evaluated by using the “Kappa statistics”. Results: Sixty-eight patients with 72 lesions insert ignore into journalissuearticles values(31 malignant and 41 benign); were analyzed. The sensitivity/specificity for AP and AP+DWI for reader 1 was 67.7/90.2% and 80.6/87.8%, respectively, and for reader 2 was 67.7/92.6% and 70.9/90.2%, respectively. The sensitivity/specificity for FDP for reader 1 was 83.7/85.3% and for reader 2 was 80.6/90.2%. The IOA in the BI-RADS category assessment was almost perfect in all models between two readers insert ignore into journalissuearticles values(the kappa value was 0.907, 0.825, and 0.858 in AP, AP+DWI, and FDP, respectively);. Conclusion: FDP showed greater diagnostic efficiency in the characterization of tumor biology as compared to AP and AP +DWI. Combining AP with DWI improved the diagnostic performance of MRI for the determination of malignancy.
