UTE images yielded the smallest artefact area at 1.5T. In addition, a significant difference in mean artefact area was found between images at 1.5 and 3.0T field strengths (p50.028) and between images from GRE and SE pulse sequences (p50.005).

Both are of great value to the patient in terms of diagnosis and comfort. 3T is ideal for imaging small bones, breast MRI, musculoskeletal MRI, neurological …

WitrynaComparing 3.0T and 1.5T machines, it means that the 3.0T scanner may be able to throughput more patients in the same amount of time with similar image quality to the 1.5T scanner. Of course, in facilities with relatively low-volume scanning needs, throughput may be a negligible factor. Artifacts.
