Truncation May Mimic Pathology

Answer this...

What pathology might truncation artefact mimic?

Truncation artefacts can obscure normal anatomy and be mistaken for pathology, for example a pseudo tear of the knee meniscus. It is particularly problematic in spinal imaging, in which they may generate a line down the centre of the cord which may be misinterpreted as a syrinx (fluid-filled cavity).
