CT – CT scan stands for computed tomography scan. It is also known as a CAT (Computer Axial Tomography) scan. It is a medical imaging method that employs tomography, a process of generating a two-dimensional image of a slice or section through a 3-dimensional object (a tomogram).

PET CT - Positron emission tomography - computed tomography (known by its acronym PET-CT or PET/CT) is a medical imaging technique using a device which combines in a single system a Positron Emission Tomography (PET) and an x-ray Computed Tomography, so that images acquired from both devices can be taken sequentially, in the same session from the patient and combined into a single superposed image.
