What kind of scan is a CT scan?
Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical imaging test. Like traditional x-rays, it produces multiple images or pictures of the inside of the body. The cross-sectional images generated during a CT scan can be reformatted in multiple planes. They can even generate three-dimensional images.
Where are the heart structures on a CT scan?
To remind ourselves, we can see the axial plane on the top left-hand image, the coronal plane on the bottom left-hand image, and the sagittal on the bottom right-hand image. Let us now look at the various structures that we can see at the midportion of the left ventricle. We can now see [00:05:30] what we call the four-chamber view.
