Aims and objectives

To create an abbreviated breast MRI protocol (FAST) and to compare it with the complete protocol (FULL) to evaluate the diagnostic accuracy and the time of interpretation of the images using BI-RADS categorization.

Methods and materials

We conducted a retrospective study with 100 consecutive women who underwent breast magnetic resonance imaging (MRI) between January and February 2014. All patients performed a complete breast MRI protocol that was compared with an abbreviated protocol (pre-contrast sequence, second post-contrast sequence, subtraction of post and pre-contrast images) (Fig. 1 to 3). Both the abbreviated protocol (FAST) and the complete protocol (FULL) were analyzed by at least two radiologists with more than 10 years of experience, who classified the exams as positive or negative and described...

Results

From the 100 patients, 4 were classified as BI-RADS 5 or 6 and 16 as BI-RADS 4. In these 20 patients there were complete agreement between the readers regarding the final BI-RADS categorization in FAST and FULL protocols. Despite the BI-RADS agreement, in 4 of these 20 patients we found one or more lesions in the FULL protocol that were not seen in the FAST one. In relation to BI-RADS 1, 2 and 3 the agreement was smaller mainly due to the presence or absence...

Conclusion

Our data provide evidence that the abbreviated protocol (FAST) decrease interpretation time without compromising the accuracy of the method to detect malignant or suspect lesions.
