Medical illustrations and diagrams

High-quality medical illustrations and diagrams form an important part of Radiopaedia.org. 

Illustrations should have sufficient detail to accurately depict both the basic anatomy of the region and pathology of the condition, in a clear and understandable manner. "Free-style" drawing is discouraged. 

Illustrations should also be of high enough resolution as to view all relevant structures easily. Illustrations do not need to contain anatomic structures that are not relevant to the condition being depicted.

  • minimum resolution: 1600x1600 pixels
  • square image ratios only: all other image dimensions are automatically converted to square resolutions with black extension of the canvas when uploaded
  • header labels at the top of the image should be in bold with a leading capital letter
  • structure labels should be all lower-case (Eponyms excepted) in regular font (no bold or italic)
  • labeled structures should be indicated using a fine black or white line to the label
    • no arrowheads (these are distracting and do not add to clarity)
    • lines are preferably horizontal, vertical, 45 degrees or a combination of these
  • use 'drop shadow' with white text and lines

Google Open Sans is the preferred font for all Radiopaedia content.  It is a free Google font and can be installed on Windows and Mac computers. 

Acceptable alternatives:

  • Windows: Myriad Pro
  • Mac: Helvetica Neue
  • the artist's name or initials may be contained within the image in a non-obstructive, non-distracting location, preferably in the bottom right corner; this should not be larger in the vertical dimension than the smallest font size in the image
  • creative commons license is at artist’s discretion, however, the default on Radiopaedia is BY-NC-SA
  • do not watermark images

The illustration background color should ideally be plain white, plain black, or black with a subtle circular grey gradient. 

The following templates illustrate the above requirements and can be easily modified to suit your illustration.  Each file includes plain white, plain black and gradient backgrounds.
