Is a PET scan machine the same as a CT scan machine?
They use different materials: CT scans pass x-rays through the body to create images. A PET scan uses a radioactive material which emits energy. The energy is then detected by a special camera to produce images. A PET scan is more time-consuming: A CT scan is performed in minutes.
What is the difference between a PET and a PET-CT?
A CT scan shows detailed pictures of the organs and tissues inside your body. A PET scan can find abnormal activity and it can be more sensitive than other imaging tests. It may also show changes to your body sooner. Doctors use PET-CT scans to provide more information about the cancer.
What is a PET TAC scan?
A PET-CT scan combines a CT scan and a PET scan. It gives detailed information about your cancer. The CT scan takes a series of x-rays from all around your body and puts them together to create a 3 dimensional (3D) picture.
What is scintigraphy used for?
A procedure that produces pictures (scans) of structures inside the body, including areas where there are cancer cells. Scintigraphy is used to diagnose, stage, and monitor disease. A small amount of a radioactive chemical (radionuclide) is injected into a vein or swallowed.
Do all cancers show up on PET scan?
Not all cancers show up on a PET scan. PET scan results are often used with other imaging and lab test results. Other tests are often needed to find out whether an area that collected a lot of radioactive material is non-cancerous (benign) or cancerous (malignant).
How is scintigraphy performed?
Scintigraphy is used to diagnose, stage, and monitor disease. A small amount of a radioactive chemical (radionuclide) is injected into a vein or swallowed. Different radionuclides travel through the blood to different organs.

How much does a PET-CT scanner cost?
PET-CT scanners come in both fixed and mobile versions, and whether you buy new, used or refurbished, price can vary across manufacturers and models. A new generation PET-CT machine can cost between $1.5 and $2 million.
What is the difference between PET/CT and PET/MRI?
Single photon emission CT/CT (SPECT/CT) and positron emission tomography/CT (PET/CT) units can perform both exams at the same time. PET/MRI is an emerging imaging technology. It is not currently available everywhere. A PET scan measures important body functions, such as metabolism.
What does a PET scan look like?
What does the equipment look like? A PET scanner is a large machine with a round, donut-shaped hole in the middle. It looks like a CT or MRI unit. Multiple rings of detectors inside the machine record the energy emissions from the radiotracer in your body.
