X-ray arteriogram of a child (1899). Early X-ray showing in fine detail the arteries in a child's body. The X-ray was made in 1899 at St. Thomas' Hospital in London,and published in the Archives of the Roentgen Ray. It was titled: "An injected infant". The cadaver of a young boy was injected,at the femoral artery of the leg,with four pounds of mercury. Under X-ray,arteries of the limbs,abdomen,heart,neck and face are highlighted. This important diagnostic technique was later to become known as an arteriogram or angiogram. It took,however,many years before harmless X-ray opaque substances were developed which could be injected to show arteries in living patients |
