As modern medicine and technology continue to advance, PET CT scan in Chandigarh have become quite revolutionary, offering the latest in the way of diagnostic techniques. PET CT scans have been effective in detecting, staging, and monitoring a variety of health concerns in individuals. PET CT scans are very sophisticated and meld imaging techniques that allow professionals to assess the functionality of the structure of internal organs and tissues simultaneously. While imaging techniques before focused on structural images, PET CT imaging allows Doctors in real-time to see and assess the functionality of many of the organs of the body, while also seeing if there are any abnormalities or changes. In this article, we will discuss in detail the PET Scans and when they are used for cancer diagnosis.

What is a PET scan?
A PET scan in Chandigarh is short for Positron Emission Tomography. A PET scan is a procedure to produce live images of internal organs along with information on physiological activities. A small safe amount of radioactive material is ingested; the radioactive material is called the “tracer” because it can be injected into the patient. The PET scanner will also highlight the tissues and organs that absorbed the most radiotracer; this indicates anything abnormal related to health. PET scans can be done anywhere in the world and are a very useful test to detect, diagnose, and monitor treatment for cancerous lesions. PET scans can assist clinicians in evaluating some heart and brain conditions, in addition to other conditions.
How does a PET scan differ from a CT scan or an MRI?
The major difference between a PET scan in Mohali, and imaging such as CT or MRI that use X-rays or magnets and radio waves to generate chemical imaging is that a PET scan can show real-time functions of the tissues and organs. CT or MRI imaging provides still imaging (static pictures) of the tissues that can’t show or prove that a tissue is actually functioning. They provide chemical imaging, but can’t show if a tissue is functioning because they are still images. PET scans provide real-time diagnostic imaging, improving the evaluation of the functional tissues of the body. Hospitals have also started to utilize PET scan imaging with CT imaging to give even further imaging results in 3D space and overall better imaging results.
A PET CT scan plays a pivotal role in the diagnosis, staging, and follow-up of cancer. It combines metabolic and structural imaging of different organs in order to enable doctors to plan treatments and track the progress of the treatment of every patient.If you are looking for the best pet ct scan centre in Mohali, or the best PET CT Scan in Chandigarh, Sohana Hospital might just be the best option for you.
