An X-ray image of the bladder taken after injecting a special dye to make it visible on the film.
Combining Greek 'kystis' (bladder) with '-gram' (a written record or image). This medical imaging term arose in the early 20th century when X-ray technology made internal imaging possible.
Doctors use cystograms to see if there are stones, tumors, or damage inside your bladder without surgery—it's like taking a picture of the inside of your body!
