Positron emission tomography PET is a test that uses a special type of camera and a tracer radioactive chemical to look at organs in the body. The tracer usually is a special form of a substance such as glucose that collects in cells that are using a lot of energy, such as cancer cells. During the test, the tracer liquid is put into a vein intravenous, or IV in your arm. Emergency management or disaster management is the organization and management of resources and responsibilities for dealing with all humanitarian aspects of. CRPK11195. PET imaging of activated microglia with TSPObinding radioligands is being increasingly utilised in MS research. The first in vivo TSPOPET pilot. Positron emission tomography PET is a test that uses a special type of camera and a special test medicine radioactive tracer to look at organs in the body. Pets and Disaster Why You Need to Be Prepared H urricanes, floods, wildfires, hazardous material spillsdisasters can strike anytime, anywhere. If you think you. The tracer moves through your body, where much of it collects in the specific organ or tissue. The tracer gives off tiny positively charged particles positrons. The camera records the positrons and turns the recording into pictures on a computer. PET scan pictures do not show as much detail as computed tomography CT scans or magnetic resonance imaging MRI because the pictures show only the location of the tracer. The PET picture may be matched with those from a CT scan to get more detailed information about where the tracer is located. A PET scan is often used to evaluate cancer, check blood flow, or see how organs are working. Why It Is Done. A positron emission tomography PET scan is done to Study the brains blood flow and metabolic activity. A PET scan can help a doctor find nervous system problems, such as Parkinsons disease, multiple sclerosis, transient ischemic attack TIA, amyotrophic lateral sclerosis ALS, Huntingtons disease, stroke, and schizophrenia. Find changes in the brain that may cause epilepsy. Evaluate some cancers, especially lymphoma or cancers of the head and neck, brain, lung, colon, or prostate. In its early stages, cancer may show up more clearly on a PET scan than on a CT scan or an MRI. See how advanced a cancer is and whether it has spread to another area of the body metastasized. It is often necessary to do both CT and PET scans to evaluate cancer. Help a doctor choose the best treatment for cancer or to see how well treatment is working. PET scans may also be done to see whether surgery can be done to remove a tumor. Help diagnose Alzheimers disease when the symptoms are not clear or when a person has dementia symptoms at a young age usually younger than 6. This is called amyloid imaging. Find poor blood flow to the heart, which may mean coronary artery disease. Find damaged heart tissue, especially after a heart attack. Help choose the best treatment, such as coronary artery bypass graft surgery, for a person with heart disease. Continued. How To Prepare.

A positron emission tomography PET scan is done in a hospital nuclear medicine department or at a special PET center by a radiologist or nuclear medicine specialist and a technologist. You will lie on a table that is hooked to a large scanner, camera, and computer. During the test. The radioactive tracer is usually given in a vein IV. You may need to wait 3. During this time, you may need to avoid moving and talking. The PET scanner, which is shaped like a doughnut, moves around you. The scanned pictures are sent to a computer screen so your doctor can see them. Many scans are done to make a series of pictures. It is very important to lie still while each scan is being done. At some medical centers, a CT scan will be done at the same time. Continued. For a PET scan of the brain, you will lie on a bed. You may be asked to read, name letters, or tell a story, depending on whether speech, reasoning, or memory is being tested. During the scan, you may be given earplugs and a blindfold if you do not need to read during the test to wear for your comfort. If you are having a PET scan of your heart, electrodes for an electrocardiogram EKG, ECG will be put on your body. During the test, you will be alone in the scanner room. The technologist will watch you through a window and you will be able talk to him or her through a two way intercom at all times. The test takes 1 to 3 hours. After the test.

If you dont feel well during or after the test, tell the person who is doing the test. You may feel nervous inside the PET scanner. Risks. There is always a slight chance of damage to cells or tissue from radiation, including the low levels of radiation used for this test. But the chance of damage is usually very low compared with the benefits of the test. Most of the tracer will be flushed from your body within 6 to 2. Allergic reactions to the tracer are very rare. In rare cases, some soreness or swelling may develop at the IV site where the radioactive tracer was put in. Apply a moist, warm compress to your arm. Results. Positron emission tomography PET is a test that uses a special type of camera and a tracer radioactive chemical to look at organs in the body. The radiologist may discuss preliminary results of the PET scan with you right after the test. Complete results are usually available in 1 to 2 days. Instrumental Church Music. Positron emission tomography PET Normal Blood flow is normal and organs are working well. The flow and pattern of the tracer shows normal distribution in the body. Abnormal Heart Decreased blood flow and increased glucose metabolism may show that the blood vessels are narrowed or blocked. This may mean coronary artery disease CAD is present. Decreased blood flow and glucose metabolism may mean that heart tissue is scarred and damaged, such as from a heart attack. Brain Tumor detection Areas of increased glucose metabolism may mean a tumor is present. Continued. What Affects the Test. Reasons you may not be able to have the test or why the results may not be helpful include Being pregnant. A PET scan is not usually done during pregnancy because the radiation could harm the unborn baby fetus. Using caffeine, tobacco, or alcohol in the past 2. Not being able to lie still for the test. Using sedatives. Taking medicines, such as insulin, that change your metabolism. Having recently had surgery, a biopsy, chemotherapy, or radiation therapy. What To Think About. References. Citations.
