Webb15 juli 2016 · Computed tomography (CT) was created in the early 1970s to overcome many of these limitations ().By acquiring multiple x-ray views of an object and performing mathematical operations on digital data, a full 2D section of the object can be reconstructed with exquisite detail of the anatomy present ().During the years since its … WebbMRI (magnetic resonance imaging) is a type of scan that uses magnetism and radio waves to take pictures of inside the body. The scan takes between 15 and 90 minutes. You might have one to find out whether you have cancer and if you do to measure how big it is and whether it has spread. You might also have one to see how well treatment is working.
