Introduction to Radiology:

Types of studies

Image A is an MR (magnetic resonance) image of the upper legs. You can see the thigh bone (femur) in the center of each leg.

Image B is a CT (computed tomography) of the chest. You can see ribs along the sides and the heart in the middle.

Image C is the hardest to figure out. It is an US (ultrasound) of the heart. Ultrasound images tend to be a bit blurry, so you usually need labels to show you what you are looking at. A strength of US is that it can show you moving pictures easily. This can help in seeing what part of the body is displayed. It is much easier to see that this is the heart if you look at the movie instead of the single still image.
