# Explore and Review SNOMED CT

SNOMED CT browsers and other applications that enable access SNOMED CT concepts allow the content and structure of the terminology to be explored. This exploration can serve many different purposes, ranging from allowing people to get a broad idea of the scope of SNOMED CT to looking for specific concepts that interest them. The same applications can be used to enable a more thorough review of the terminology in a particular specialty area to assess the breadth, depth and applicability of SNOMED CT to a particular set of requirements. Tools that enable visual review of a released SNOMED CT Edition are also valuable for quality assurance and when considering requests for addition or changes to the terminology.
