A positron emission tomography scan pet scan is a type of imaging test that is used to diagnose many diseases in a person’s body. Pet scans are used to uncover areas of the body where the rates of certain chemical activities increase.

A PET scan can tell a patient’s physician how their body uses oxygen, how their body processes glucose and their bloodstream. These specialized scans can inform the patient’s physician about problems occurring at the cellular level, helping to identify and evaluate some complex systemic conditions and diseases.

The most common issues are PET scans to identify neurological disorders, cancer, and heart problems. About two million PET scans are performed annually in the United States.

Now get full details on positron emission tomography scan.
PET scans are used to diagnose and evaluate the progression of many different disorders, diseases and conditions.

The most common use of PET scans is for the detection, diagnosis and progression of cancer in the body and for the evaluation of cancer treatment. Other causes of positron emission tomography scans may be used to diagnose conditions associated with deterioration of brain function such as Parkinson’s disease, Huntington’s disease, Alzheimer’s disease, epilepsy, neurological accidents, and other types of dementia.

PET scans can be used to evaluate the flow of blood in a patient’s heart muscle tissue to evaluate the efficacy of a therapeutic procedure to help the blood flow to the heart muscle. Positron emission tomography scans can help identify lesions or lesions seen in a patient’s lung tissue in a chest CT or chest X-ray.

PET scan preparation

A PET Scan is performed on an outpatient basis, which means that the patient who undergoes the test will be able to go home immediately. Before having a PET Scan, a patient should inform their physician about all the vitamins, herbal remedies, supplements, and medications they are taking.

Certain medications, supplements and vitamins may cause patients to follow additional instructions before their positron emission tomography scan.

Patients should tell their doctor if they are pregnant or if there is a possibility that they are pregnant. In most cases, patients will be instructed not to consume food and any drinks at least six hours to eight hours before their PET scan.


If a positron emission tomography scan involves examining any part of their heart, they are usually advised not to consume caffeine twenty-four hours before the scan.

We can compare PET scans with CT and MRI scan tests.
Positron emission tomography scans can reveal problems occurring at the cellular level of the patient’s body in contrast to CT scans and MRI scans. A CT scan uses special X-ray equipment to create detailed images inside a patient’s body.

MRI scans use radio frequency pulses and magnetic fields to produce detailed images of the patient’s internal structures such as bone, organs, and other soft tissues.

CT scans and MRI scans can only reveal changes in the patient’s body that occur in the later stages of their associated disorder or disease. CT scans and MRI scans can bring changes in the patient’s body until the disease or condition changes the composition of tissues or organs in their body. In some cases, a person must have a PET-MRI scan or PET-CT scan.

By combining MRI or CT scans with a positron emission tomography scan, the computer can mesh images from two scans for more accurate diagnosis.

Also, become familiar with the risks of PET Scans.

Risk of PET Scan.

Positron emission tomography scans have lower risk with them than MRI scans, CT scans, and standard X-rays. A minimal amount of radiation will be generated during a PET Scan because a substance called radio tracer chemistry is used.

Radiotracer chemicals can also be referred to as radionuclides, radiopharmaceuticals, or radioactive tracers. The radiotracer used in a positron emission tomography scan is a molecule that contains glucose and an attached radioactive component.

A patient may have an allergic reaction to substances used as radioactive tracers. Individuals known to be allergic to aspartame, saccharin, and iodine are at greater risk of experiencing problems during their PET scans.

Patients taking asthma, heart disease, dehydration, kidney disease and beta-blockers, non steroidal anti-inflammatory and interleukin-2 are at greater risk of experiencing complications with PET Scans.
