In this article, we will discuss about the difference between PET scan and the CT scan. We will also discuss some common questions related to the procedures.
PET scan uses radioactive tracer for the detection of abnormalities at the cellular level. This helps in easy and early detection of cancer and tumors, which can be treated easily and early. CT scan uses X-rays to create the 3D images of the conditions or abnormalities in the patient. The procedure uses motorized X-rays for the detection of abnormalities in the body. It is used to detect the fractures, internal bleeding and tumours. It gives anatomical view of the cancer and helps to design the treatment.
