Musculo-skeletal magnetic resonance imaging using inversion recovery pulse sequences at 0.08 T.
The potential of magnetic resonance imaging (MRI) for the assessment of musculo-skeletal tumours has until recently been underestimated. Most reports in the literature describe the MRI appearances of musculo-skeletal tumours using spin-echo pulse sequences with high field, superconductive magnets. This paper describes the use of inversion recovery pulse sequences using a low field resistive magnet for the study of musculo-skeletal disorders. Thirty patients who had either radiological evidence of a bone tumour or a soft tissue mass were studied by low field MRI and inversion recovery, and calculated T1 images compared with the tissue histology of the mass. It has been found that inversion recovery images display the size and extent of both bone and soft tissue tumours and that the use of coronal and axial images enable clear display of the relationship of bone and soft tissue tumours to the major blood vessels, muscle and cortical bone.
