    DICOM can hold raw pixel data and also can hold JPEG-compressed pixel data, as well as many other formats. The transfer syntax tag of the DICOM file gives you the compression protocol of the pixel data within the DICOM. The first thing is to figure out whether you need lossless or lossy compression.
