Free-breathing radial 3D fat-suppressed T1-weighted gradient echo (r-VIBE) sequence for assessment of pulmonary lesions: a prospective comparison of CT and MRI.

Cancer imaging : the official publication of the International Cancer Imaging Society

Yu N, Duan H, Yang C, Yu Y, Dang S.
PMID: 34930463
Cancer Imaging. 2021 Dec 20;21(1):68. doi: 10.1186/s40644-021-00441-3.

PURPOSE: To determine whether the pulmonary MR imaging with free-breathing radial 3D fat-suppressed T1-weighted gradient echo (r-VIBE) sequence can detect lung lesions and display lesion profiles with an accuracy comparable to that of computed tomography (CT), which is the...
