Stacks are a set of sequential images that can be scrolled. Sequential images from cross-sectional modalities (e.g. CT/MRI) or time-resolved modalities (e.g. DSA) and should be presented as a scrollable stack, rather than as multiple single images.
Stacks should ideally contain less than 100 images per stack. There are two ways of uploading stacks: automatic and manual.
To upload cases from a DICOM/PACS as stacks to Radiopaedia, please use one of our uploaders. This is by far the easiest way of creating great cases.
To manually upload a stack all you need to do is zip (see below) sequentially numbered images and upload the zip file in exactly the same way you would upload a single image.
- MacOS: highlight images, right click and select 'compress'
- Windows: highlight images, right click and 'send to compressed (zipped) folder'
Make sure the images are sequentially numbered, preferably with leading zeros (although this is not mandatory) as follows:
It is worth keeping in mind that the middle image within a stack is used as the thumbnail image by default and that often, this will not be a good representation of the pathology. Therefore, it is often helpful to select a specific different key image.
Please use the list box under the stack to specify the appropriate plane/projection and sequence/contrast phase.
Although at present each stack can have its own specific description, this feature is going to be deprecated in the near future, so please avoid relying on this.
