Feasibility of online non-rigid motion correction for high-resolution supine breast MRI.

ABSTRACT:

Purpose

Conventional breast MRI is performed in the prone position with a dedicated coil. This allows high-resolution images without breast motion, but the patient position is inconsistent with that of other breast imaging modalities or interventions. Supine breast MRI may be an interesting alternative, but respiratory motion becomes an issue. Motion correction methods have typically been performed offline, for instance, the corrected images were not directly accessible from the scanner console. In this work, we seek to show the feasibility of a fast, online, motion-corrected reconstruction integrated into the clinical workflow.

Methods

Fully sampled T₂ -weighted (T₂ w) and accelerated T₁ -weighted (T₁ w) breast supine MR images we
