Computed tomography (CT), also known as "CAT scanner" (Computed Axial Tomography) uses X-rays to create detailed pictures that show cross-sections, or slices, of structures in the body.
X-rays are taken from a variety of different angles and processed through a computer to produce a three-dimensional (3-D) image known as a tomogram rather than the overlapping images typically produced by conventional X-ray exams.
CT scan is a noninvasive procedure and is considered to be safe as the amount of radiation
used is low.
