Abbreviated MRI Protocols: Efficacy in Improving Acquisition and Interpretation Time in Breast Cancer

Abstract

Background: To be cost-effective, the abbreviated magnetic resonance imaging (MRI) protocols have to be proved to reduce  examination and reading times, while being clinically effective.

Objective: To investigate the efficacy of these protocols in enhancing the  efficiency of exams and reducing interpretation time. The study reviews the rationale behind abbreviated protocols and why they are an  essential evolving tool in breast screening programs.

Patients and methods: This was a prospective randomized study. 60 female  patients were examined. They were presented to Kasr Al-Ainy Medical School Breast Unit for screening. Patients were stratified using a  risk assessment model. Different risk categories were included.

Results: Abbreviated MRI is proved to be a cost-effective method of  screening for breast cancer. It has found to be faster to be performed compared with traditional mammogram, as given all the  preparation required and proper position needed in mammograms, MRI would be a better modality. Average time for completing  abbreviated MRI (AB-MRI) was 5.1 minutes, while mammograms took 10 min. Reading AB-MR took an average of 4.7 minutes, while  traditional mammograms 5.7minutes. Regarding efficacy, when compared to traditional screening methods, AB-MR showed the  following: 100% negative predictive value (NPV), 85.7% specificity, 50% positive predictive value (PPV), and 100% sensitivity in breast  cancer.

Conclusion: Abbreviated MRI was found to be an efficient method to identify breast cancer, with shorter imaging and reading  times.
