Yes, if their fear prevent's them from entering, they can be sedated. Although for entering at will, it depends on how strong their claustrophobia is, E.g. I have claustrophobia but unless I fell like I will get stuck, I am fine. And by get stuck, that does NOT include elevators (For me)
Yes, PET scan (positron emission tomography) is a type of imaging test used on humans to visualize how organs and tissues are functioning. It is commonly used in the diagnosis and monitoring of conditions such as cancer, brain disorders, and heart disease.
The technique is called positron emission tomography (PET). It involves injecting a radioactive form of glucose into the bloodstream, which is then taken up by active brain regions. The scanner detects the emitted positrons to create a map of brain activity.
Claustrophobic patients are typically afraid of small or confined spaces where they feel trapped and unable to escape. This can lead to feelings of panic or anxiety when in situations such as crowded elevators, tunnels, or small rooms with limited exits.
DefinitionA brain positron emission tomography (PET) scan is an imaging test that uses a radioactive substance (called a tracer) to look for disease or injury in the brain.Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structure of the brain, a PET scan shows how the brain and its tissues are working.Alternative NamesBrain nuclear medicine scan; Brain positron emission tomographyHow the test is performedThe health care provider will inject a small amount of a radioactive material into one of your veins, usually on the inside of the elbow. Or you may inhale the radioactive material as a gas. The substance travels through the blood and collects in the tissues of the brain.You will be asked to wait nearby as the radioactive substance is absorbed by your body. This usually takes about 1 hour.Then, you will lie down on a table that slides into a tunnel-shaped hole in the center of the PET scanner.The PET machine detects energy given off by the radioactive substance and changes it into 3-dimensional pictures. The images are sent to a computer, where they are displayed on a monitor for the health care provider to read.You must lie still during the PET scan so that the machine can produce clear images of your brain. You may be asked to read or name letters if your memory is being tested.The test takes between 30 minutes and 2 hours.How to prepare for the testYou must sign a consent form before having this test. You will be told not to eat anything for 4 - 6 hours before the PET scan, although you will be able to drink water.Tell your doctor if you are pregnant or think you might be pregnant.Also tell your doctor about any prescription and over-the-counter medicines that you are taking, because they may interfere with the test.Be sure to mention if you have any allergies, or if you've had any recent imaging studies using injected dye (contrast).People with diabetes who take insulin injections will need special preparation. Call the PET scan office the day before the study for instructions.During the test, you may need to wear a hospital gown. Take off any jewelry, dentures, and other metal objects because they could affect the scan results.How the test will feelYou will feel a sharp prick when the needle with the radioactive substance is inserted into your vein. You shouldn't feel anything during the actual PET scan.Why the test is performedA PET scan can reveal the size, shape, and function of the brain, so your doctor can make sure it is working as well as it should. It is most often used when other tests, such as MRI scan or CT scan, do not provide enough information.This test can be used to:Diagnose cancerEvaluate a patient with epilepsy who may need surgeryHelp diagnose dementia if other tests and exams do not provide enough informationSeveral PET scans may be taken to determine how well you're responding to treatment for cancer or another illness.Normal ValuesThere are no problems detected in the size, shape, or function of the brain. There are no areas in which the radiotracer has abnormally collected.What abnormal results meanAbnormal results may be due to:Alzheimer's disease or dementiaBrain tumors(cancerous and non-cancerous)EpilepsyMovement disorders (such as Parkinson's disease)What the risks areThe amount of radiation used in a PET scan is low. It is about the same amount of radiation as in most CT scans. Also, the radiation doesn't last for very long in your body.However, women who are pregnant or are breastfeeding should let their doctor know before having this test. Infants and fetuses are more sensitive to the effects of radiation because their organs are still growing.Before receving the contrast, tell your health care provider if you take the diabetes medication metformin (Glucophage) because you may need to take extra precautions.It is possible, although very unlikely, to have an allergic reaction to the radioactive tracer. Let your doctor know if you have ever had an allergic reaction to injected contrast dye. Some people have pain, redness, or swelling at the injection site.Special considerationsIt is possible to have false results on a PET scan. Blood sugar or insulin levels may affect the test results in people with diabetes.Most PET scans are now performed along with a CT scan. This combination scan is called a PET/CT.ReferencesFoldvary-Schaefer N, Wyllie E. Epilepsy. In: Goetz GC. Textbook of Clinical Neurology. 3rd ed.

The list is innumerable that would exceed the discussion window. Essentially, jobs that require long periods of close quarters; anything that bound you in a small space should be avoided. For example, Astronaut; aircraft fuel cell maintenance; numerous military disciplines require gas mask attire; a claustrophobic's worst nightmare would probably be joining the Navy and being sent to serve on a submarine. Frankly, to be perfectly honest, a claustrophobic should avoid military service entirely. because the unpredictability of that career path combined with the danger you may present to others.
Yes, there are apps available that can scan pet microchips. These apps use the smartphone's camera to scan the microchip and provide information about the pet.

Are you talking about a PET scan?
One drawback of having an MRI scan is that it can be claustrophobic for some people, as the machine is a tight space that patients must remain still in for an extended period of time.
A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.
Yes, but bone scan has to be completed first.
they are not good 4 every1 as some people can get claustrophobic and some people may not be a certain size for this scan.
A PET scan, or Positron Emission Tomography, is used to scan internal organs for abnormalities, like tumors, or cancer. PET scans for animals may cost hundreds, or thousands of dollars, depending on the size of the animal, and the complexity of the scan.
no
A full body PET scan can take 30 to 45 minutes. A scan of a single lamp or a single organ can take as little as 10 minutes.
Yes, many modern CT scan machines are designed to accommodate claustrophobic patients. These machines often have a wider opening and shorter scanning times, which can help reduce feelings of confinement. Additionally, healthcare providers may offer sedation or other coping strategies to help manage anxiety during the procedure. It's always best to discuss any concerns with your healthcare team prior to the scan.
the bad thing about an MRI scan is if you are claustrophobic or don't like small spaces, it will be difficult because you have to wait there for a while. another bad thing is that it is very expensive as the machine is expensive!
