Abstract

Conventional full-protocol breast magnetic resonance imaging (MRI) includes T2-weighted imaging and dynamic contrast-enhanced MRI, consisting of pre-contrast and four to six post-contrast T1-weighted images. By contrast, abbreviated breast MRI consists of pre-contrast and a single post-contrast T1-weighted image as core sequences, along with reconstructed subtraction and maximum intensity projection images. Additional sequences, such as T2-weighted imaging, diffusion-weighted imaging, and a second postcontrast T1-weighted image, can be included in the abbreviated protocol based on user preferences; however, the recommended total acquisition time is less than 10 minutes. Using abbreviated MRI, the scan time is reduced, and MRI throughput increases, which can lower costs and improve accessibility. Moreover, the current evidence consistently suggests that the accuracy of abbreviated breast MRI in detecting breast cancer is comparable to that of full-protocol MRI. With these advantages, abbreviated breast MRI may be increasingly used for screening women at average to intermediate risk. This review discusses the background of abbreviated MRI, the results of clinical studies, and outstanding issues for future consideration.
