The ability to scroll through a stack of images is the cornerstone of cross-sectional imaging and is now expected for all cases containing CT or MRI. In the new uploader (available as an option in your user settings) you can crop, pan and zoom images and stacks. Therefore, for any diagrams or images with non-black background please ensure the image is square so that it displays well. Any space not taken up by the image will have a black background. Most images on the site are displayed in a square 1:1 container. We keep all the original images and optimize the images for display on browsers.
x-ray: variable but generally larger than 1600 x 1600 px. MRI: sequence-specific ranging from 128 to 1024 px. Never (except for plain films and mammography) upload images that are smaller than the size acquired: Thus uploading a larger size, particularly native modality resolution is recommended. accepts (essentially) any size and then resizes it to serve up to viewers. 
DICOM: lossless, an original image format that is the standard for storing and transmitting medical images Uploading DICOM images to Radiopaedia directly (with full client-side anonymisation) is available as an opt-in beta feature in the user settings.PNG: non-lossy, reasonable size, the preferred format for diagrams, as edges and text will be crisp.
JPG: small size but degraded by compression use quality of 80 or above to minimize image degradation. In the new uploader (available as an opt-in beta feature in the user settings) you can crop/pan/zoom images prior to uploading. are appropriate for teaching (slice thickness, views, etc.). are of sufficient resolution (see below). the images have appropriate window/level/contrast/brightness. We are not all blessed with state-of-the-art hardware, but that is no excuse for poorly optimized images.īefore uploading an image please ensure that: Radiology is all about image quality and as such it is crucial for the site as a whole and for your online contributions to be of high quality.
