Probably worth mentioning also that "used in DICOM standard" is true but possibly misleading to someone unfamiliar with it.

DICOM is a vast standard. In it's many crevasses, it contains wire and file encoding schemas, some of which include (many different) image data types, some of which allow (multiple) compression schemes, both lossy and lossless, as well as metadata schemes. These include JPEG, JPEG-LS, JPEG-2000, MPEG2/4, HVEC.

I think you have to encode the compression ratio as well, if you do lossy compression. You definitely have to note that you did lossy compression.
