What are some common uses of the procedure? The slices thus acquired may be transferred digitally to a linear accelerator which is used to perform precise bombardment of the target areas using high energy photons radiosurgery. Metal objects including jewelry, eyeglasses, dentures and hairpins may affect the CT images and should be left at home or removed prior to your exam.
When the radiotracer is given intravenously, you will feel a slight pin prick when the needle is inserted into your vein for the intravenous line.

These images can then be interpreted by a radiologist on a computer monitor. For more information on how a CT scan is performed, see Computed Tomography. An intravenous bolus injection of a dose of recently produced 2-FDG or 3-FDG is made, usually by a vein in one of the arms.
Instead, you are encouraged to drink water. When swallowed, the radiotracer has little or no taste. These imaging scans use radioactive materials called radiopharmaceuticals or radiotracers.

Diabetic patients will receive special instructions to prepare for this exam. Nuclear medicine procedures can be time consuming.
The risks of the treatment are always weighed against the potential benefits for nuclear medicine therapeutic procedures.With PET+CT, PET is done on a PET-only system followed by a CT scan in a standalone CT scanner, with the two image sets fused using specialized software.
With PET/CT, PET and CT are acquired, nearly simultaneously, in the same killarney10mile.comon: S. Central Ave, Glendale,CA. Mar 29, · CT vs PET SCAN Computed tomography and Positron Emission tomography are both nuclear medicine scans used to detect abnormalities in the different organs of the body.
It is an imaging procedure that helps determine appropriate diagnosis and decide necessary treatment for the impending disease.
"Difference Between CT /5(6). A PET/CT scan creates detailed, computerized pictures of areas inside the body. The test merges two imaging technologies, positron emission tomography (PET) and computed tomography (CT), into one machine for a single imaging session.
Visit Cancer Treatment Centers of America (CTCA) to learn more. What is Positron Emission Tomography – Computed Tomography (PET/CT) Scanning? Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging.
