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 significant lesions according to the BI-RADS lexicon.
The variability between readers and between protocols for the classification of BI-RADS and the diagnostic accuracy were also evaluated.
