Code for methods of measuring tumor size, including physical examination, pathology, and imaging.


Changes since version true:


There are 3 broad categories of tumor size measurement methods:

  1. Pathology
    • Macroscopic size from pathology report is represented by SCT 787377000 ("Gross examination and sampling of tissue specimen (procedure)")
    • Microscopic size from pathology report is represented by SCT 104157003 ("Light microscopy (procedure)")
  2. Physical exam, represented by SCT 5880005 ("Physical examination procedure (procedure)")
  3. Diagnostic imaging
    • Imaging modalities commonly used for tumor sizing
      • X-ray represented by SCT 363680008 ("Physical examination procedure (procedure)")
      • Ultrasound represented by SCT 16310003 ("Diagnostic ultrasonography (procedure)")
      • Magnetic Resonance Imaging (MRI) represented by SCT 113091000 ("Magnetic resonance imaging (procedure)")
      • Computerized axial tomography (CAT) represented by SCT 77477000 ("Computerized axial tomography (procedure)")
      • Positron emission tomograph (PET) represented by SCT 82918005 ("Positron emission tomography (procedure)")
    • Imaging modalities that are less commonly used for tumor sizing
      • Imaging represented by SCT 363679005 ("Imaging (procedure)")

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
