Mammograms

so i've been sitting on a jury (doing my civic duty and all that) for a civil trial the last few days where the central issue is mammograms and it occurs to me that x-rays of other body parts don't seem to get special names (at least to my knowledge). do they have a name for an arm x-ray other than "x-ray of your arm?"

anyway, i wish they had picked "breast-ray" rather than "mammogram". it would make me chuckle.
