Why are PET Scans required?

When people are instructed to undergo Pet CT Scanning, they approach it with a natural apprehension as they do not have much information about the PET diagnosis procedure. The following details are constructed to familiarize patients about the whole idea of PET and why it is needed to identify any type of cancerous growth in the body.

What is a PET scan?

PET is the acronym for positron emission tomography and the procedure is to develop more detailed, three-dimensional imageries that can help in disease diagnosis in the best possible way. As it is said in the medical books, correct diagnosis is the prime step into curing any disease.

How is PET done?

PET scans use radionuclides that are radioactive substances that collect at areas where cellular activities are higher. It is learned that cancerous cells are more active than normal cells and the trackers are able to highlight these areas where cellular functioning is higher helping to capture the images more efficiently.

Apart from using it for cancer detection, the scan is also used in the diagnosis of several other medical conditions as well. In the case of cancer, it is not only used in cancer diagnosis, but in understanding the progress of the treatment being carried out, as well.

Why is PET scan required?

PET medical imaging has become one of the most reliable ways to identify cancerous growth in humans. It is especially so due to the fact that the technique is able to provide well-detailed, three-dimensional mappings of the areas where the maligned growth is found.

Let us take a look at the advantages of diagnostic nuclear medicine and PET.

  • The PET scans are particularly effective and quick in identifying cancerous growth in the body as it detects how bio-chemical reactions in certain areas of human body vary. This ability of the scan to detect the metabolic activities in the cells and associate the same with cancerous growth helps in identifying cancer even before it becomes anatomically visible. This aids in quicker diagnosis, early treatment and better chances of cure from the disease.
  • As PET scans can study the metabolic functions in cells and organs, the scan comes in handy to understand the extent of growth of cancer without having to do biopsy or surgeries to detect the same.
  • PET scan has the ability to differentiate between cancerous and non-cancerous growths inside the body. It makes the scan an excellent tool to focus and accurately administer treatment accordingly.
  • PET has positive psychological effects on patients who are intimidated by complex and fear-inducing medical procedures in determining cancerous growths.

These advantages make PET scans the most preferred and trusted way to determine cancerous growths and other types of diseases. If you have any concerns or anxieties about undergoing the procedure, you can consult your cancer clinic and have your concerns addressed immediately.
