Colon (punctuation)

Dr Jeremy Jones et al.

Colons are often used to denote the start of a list, but can also be used within a list to separate a term and its descriptor. Colon use at follows standard English style with no space preceding the colon and a space after it. 

Examples of colon use include:

  • disc level: confined to between the vertebral endplates
  • T1
    • fluid: hypointense
    • fat: hyperintense
  • T2: fluid appears hyperintense
    • haemorrhage: variable signal intensity depending on age of blood

Note: colons are not to be used within a bullet list when there is no content to add in the same line (example 2 above).
