Correction of step artefact associated with MRI scanning of long bones

Magnetic Resonance Imaging Versus Computed Tomography for Three‐Dimensional Bone Imaging of Musculoskeletal Pathologies: A Review

“…Some of the images were fat‐suppressed (eg, S‐GRE of the shoulder) or post‐processed (eg, VS‐GRE of the shoulder). Some images are reprinted with permissions from the reference given in the top left‐hand corner of the images 16–24 . Black bone/skull was reprinted by permission from Springer Nature 20 .…”

“…Second, care needs to be taken to avoid the edge of the FOV where the lower signal and field inhomogeneity may compromise the measurements 33 . As a solution, MR images can be acquired in multiple blocks, overlapping or not, to obtain the necessary information 18,24,30–32 . Such multi‐station acquisitions are, however, susceptible to slight changes in position between individual acquisitions that can compromise the geometric integrity of the bone 24 …”

Image resolution was often lower on MRI than on CT, with voxel sizes usually ranging between 0.6 mm and 1 mm in the reviewed literature (see Table 1).…”
