"Ideally, just upload the DICOM and then you don't have to worry about this. We will take care of the rest."
"it can be really hard to replicate a nice flat image when there is dense bone (when the film is completely transparent you get a lot of glare and can't see the rest)"
"Under no circumstances should any clinically relevant part of an image be altered in any way. Furthermore, under no circumstances should "realistic" or "deepfake" AI-generated images be uploaded. Doing so is a breach of the terms of use, and your account may be terminated without notice."
"JPG: small size but degraded by compression; use quality of 80 or above to minimise image degradation"
"PNG: non-lossy, reasonable size, the preferred format for diagrams, as edges and text will be crisp"
"JPG and PNG: for cross-sectional images (CT and MRI) or temporal sequences (DSA run), sequential images from a series can be uploaded as a .zip file containing sequentially numbered images; see stacks for more information"

"PLEASE avoid uploading every single thin image you have. A 650 x 0.6 mm stack is useless and takes forever to load. It is very unusual for a single series to require more than 100 images."

"Digitally exported images are strongly preferred over screenshots or photos over film."
"MRI: sequence-specific ranging from 128 to 1024 px"
"In the case uploader you can crop, pan and zoom images and stacks using the Crop tool. You can do so during upload or later. To go back to the images to edit them select Edit → Images from the case viewer."

"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 and is ideal as it will future-proof your case"
"JPG: small size but degraded by compression; use quality of 80 or above to minimise image degradation"
"JPG and PNG: for cross-sectional images (CT and MRI) or temporal sequences (DSA run), sequential images from a series can be uploaded as a .zip file containing sequentially numbered images; see stacks for more information"
"DICOM: sequential images are automatically separated into stacks when uploaded using this format; the uploader is available as an opt-in beta feature in the user settings"
"autofocus often does not work (fluffy images) so focusing on a sheet of paper with lines drawn on it placed in front of the film works well; alternatively set your focus to the central dot, and aim initially at the patient demographics (remember to exclude these or edit them out later)"
"In the case uploader you can crop, pan and zoom images and stacks using the Crop tool. You can do so during upload or later. To go back to the images to edit them select Edit → Images from the case viewer."
