Whole body magnetic resonance imaging - A valuable adjunct
to clinical examination
When Lauterbur and Damadian described the
application of magnetic resonance imaging (MRI) as a clinical
imaging tool in the early 1970s the popular belief was that
the technique would become the ultimate screening tool for
the whole body.1 2 However, similar to other modalities
limited by cost, acquisition times, availability, and artefact
produced by motion, it evolved as a technique to image stationary
body parts. Supported by technical developments in the past
decade, improved excitatory pulse sequences, and faster
methods of localising derived signal, and by increasing
awareness of the hazards of radiation imposed by traditional
techniques, the ability to use MRI as a rapid imaging tool
for the whole body has now been revisited.3-11 Reduced acquisition
times have been mirrored by a logical reduction in acquisition
costs, and the recent development of the moving MRI table
top has facilitated the clinical introduction of this technique
as a practical diagnostic tool.3
