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.
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.
