Abstract

Background: Baltzer et al introduced The Kaiser score to aid the interpretation of enhancing breast MRI lesions, the score ranges from 1 to 11, reflecting an increased probabilities of malignancy.Aim of the study: To investigate whether the application of the Kaiser score, can improve the diagnostic performance in contrast enhancing lesions classified as BI-RADS4-5 on breast MRI.Patients and method: Prospectively Data collected at oncology teaching hospital in medical city teaching complex in Baghdad, the study included 60 female patients with breast lesions classified as BI-RADS4-5 on DCE-MRI. The diagnostic efficacy of Kaiser score was evaluated according to the pathological results... . .Results: The study included 60 females with 69 suspicious breast lesions categorized as BI-RADS 4-5 lesions on DCE-MRI, 45 lesions were malignant, 24 were benign, the results regarding the diagnostic performance of the Kaiser score, showed that it has high accuracy with AUC= 94.1%, high sensitivity of 92.3%, high specificity of 86.7%, and it was 88.4% accurate in diagnosis of breast malignancy...Conclusion: This study provides evidence that the Kaiser score can be used in improving the diagnostic performance of dynamic enhanced breast MRI in BI-RADS 4-5 lesions.Breast cancer, Magnetic resonance imaging, Kaiser score. ...
