SNOMED started in 1965 as a Systematized Nomenclature of Pathology (SNOP) and was further developed into a logic-based health care terminology. [6] [7]SNOMED CT was created in 1999 by the merger, expansion and restructuring of two large-scale terminologies: SNOMED Reference Terminology (SNOMED RT), developed by the College of American Pathologists (CAP); and the Clinical Terms Version 3 (CTV3 ...
The International Health Terminology Standards Development Organisation (IHTSDO), trading as SNOMED International, is private company limited by guarantee and established under the laws of England [1] that owns SNOMED CT, a leading clinical terminology used in electronic health records.
In 2002 CAP's SNOMED Reference Terminology (SNOMED RT) was merged with, and expanded by, the National Health Service's Clinical Terms Version 3 (previously known as the Read codes) to produce SNOMED CT. [2] [3] Versions of SNOMED released prior to 2001 were based on a multiaxial, hierarchical classification system.
The first version was developed in the early 1980s by Dr James Read, a Loughborough general medical practitioner. [2] The scheme was structured similarly to ICD-9: . each code was composed of four consecutive characters: first character 0-9, A-Z (excepting I and O), remaining three characters 0-9, A-Z/a-z (excepting i,I,o and O) plus up to three trailing period '.' characters
A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography ( CAT ) scan technology is used, it is known as a full-body CT scan , though many medical imaging technologies can perform full-body scans.

What hampers the use of SNOMED-CT are systems created which do not understand the cognitive models of clinicians and which do not understand how to properly use SNOMED-CT. User interfaces can be simplified (but only so much), and still capture complex concepts, but it requires better developers than what are working on the problem today.
A notable example of applications is the reconstruction of computed tomography (CT) where cross-sectional images of patients are obtained in non-invasive manner. Recent developments have seen the Radon transform and its inverse used for tasks related to realistic object insertion required for testing and evaluating computed tomography use in ...
