Importance and Uses of PET Scans

Science & Technology
PET scan is known as Positron Emission Tomography scan where the doctor examines the patient’s body through images and detects diseases, if any. The scan utilizes a coloring agent which contains radioactive tracers. The patient has to swallow or inhale these traces to help the doctor diagnose the disease. The doctor can also inject it in the patient depending on the part of the body needs to be examined. When the internal organs and tissues absorb the tracer molecule, then the doctor is able to observe the metabolic processes in the body.

The molecules accumulate in certain parts of the body that exceed chemical secretion. It is often found that certain diseases generate a high level of chemical activity. Such areas display as bright spots when PET scanning is done. Doctors recommend performing PET scan in order to measure the flow of blood, use of oxygen and the sugar level in the body.

Why should you perform a PET scan?

A general practitioner may suggest you to carry out a pet scan oncology to examine the flood flow in the body or to detect the metabolism of your tissues and organs. PET scans can also detect issues at cellular level by presenting your doctors a clear view of the complex diseases. The scan is popularly used to identify diseases like-

  • Heart disorders
  • Cancer
  • Brain disorders
  • Issues related to Central Nervous System

The rate of metabolism is always high in cancer cells when compared to noncancerous cells. PET scans can easily recognize such cells as they generate high chemical activities. Thus, doctors mostly recommend PET scans not only to detect cancer cells but also to –
  • Check if the disease has spread to the internal organs
  • Examine whether the treatment is working and the patient is responding to it.
  • Find if there is a chance for recurrence for the disease

It is important for any doctor to carefully go through the reports, as sometimes, noncancerous cells may appear like cancer cells too. In other cases, tumors fail to appear on this scan. Thus, it is essential to re-check the internal organs ensure that nothing is left undiagnosed.

You should know that glucose is one of the main fuels of the brain. When PET scans are performed, tracing molecules are involved with glucose which is injected in the patient. Through radioactive glucose, PET scan helps to identify the part of the brain that utilizes a major part of glucose. It also detects if any abnormalities is occurring in the brain.

On the other hand, PET scan is also used for determining any disorders in the central nervous system of an individual. If you are suffering from depression, head trauma, epilepsy, Alzheimer’s disease or Parkinson’s disease, then you must opt for a PET scan to detect the actual problem.

Difference between PET scan and other similar diagnosis procedure

PET scan has a lot of contribution in the medical field. Doctors are recommending PET scans over CT scans and MRIs for detecting numerous diseases. PET scans help in detecting the metabolic changes happening at the cellular level in any organ or tissue. It plays a important role in identifying any disease in the initial stages which can be treated as soon as possible. Disorders mostly start growing at the cellular level, thus if you are facing any trouble due to internal injuries, PET scan is a must.

Benefits of PET scan diagnosis

Here are some of the immense benefits that PET scan facilitates for patients to provide them with faster improvement in their health. With the help of PET scan imaging tests, doctors can make precise diagnoses and utilize modern treatment procedures to ensure better and less-persistent treatments that result in faster improvements in the patient. PET scans enhance the comfort of the patient as it offers painless and non-invasive scans to detect any internal disorder. The time taken to perform this scan is relatively less than other tracing scans. Besides improving the experience of the patient, it also reduces the number of monitoring session that any individual has to undergo. It ensures that every abnormality is detected in one or two sessions. You can perform the process for free if you own private insurance or Medicare health insurance. It provides doctors with better quality images to help them get an accurate picture of the structure of organs and tissues. It is clinically proven, that these scans provide modern pieces of information that can change the treatment procedure to better target the stage of the cancer in a patient.

Risks drawn in PET scan imaging test

PET scan consists of radioactive tracing molecules, though its exposure to injurious radiation is negligible. However, in some cases there can be some patients who can be allergic to the tracer. If you happen to be allergic to aspartame, iodine or saccharin, then you must alert your doctor to avoid any kind of allergies. In case of pregnant women, PET scan can be harmful as the tracing molecule is not safe for developing fetuses. Thus, pregnant ladies should be kept away from such scans and should be offered some other treatment procedures.
