Short version is that a medical image, like a typical MRI, is a 3D picture at least 1024 x 1024 x 1024 pixels, meaning each image is multiple gigabytes. SQL databases don't do well at storing huge binary blobs like that.

The filesystem is a perfectly good hierarchical document-based database, and it's worth thinking about it that way in both theory and in practice.
