October 23, 2024

PET scans with CT are the advanced imaging technologies used much in the diagnosis and treatment of several medical conditions, such as cancer. If you are someone looking for the advanced PET and CT scan in Chandigarh and are already going through the healthcare system for yourself or for a dear one, you may ask how often this procedure is required. This article speaks to you about what a PET CT scan is, its importance, and how frequent it should be done.

 

What Is a PET CT Scan?

Two advanced imaging techniques named PET and CT scan are used for Cancer diagnosis: 

  1. PET Scan: PET Scan uses a radioactive substance known as tracer. After it is injected into the patient it emits positrons which are then detected by the scanner. Doctors thus get to see tissues and organs functioning and which sites exhibit heightened metabolic activity-characteristically-an indicator of disease such as cancer.
  2. CT Scan: CT scan with the help of a X-Ray takes a detailed image of the internal body structure. Such an imaging scanning will enable the doctors to have clear anatomical information about where the abnormalities identified in the PET scan are present.

It integrates a combined view by two scans, whereby the functional and structural aspects of organs and tissues are shown to be quite useful in determining the accuracy for proper diagnosis.

 

Why Are PET CT Scans Important?

Pet CT scans are very important for patients because:

1.  Cancer Diagnosis: They are the most crucial scans to be able to confirm that the presence and the spread of cancerous growths are also diagnosed.

2. Monitoring Treatment: PET CT scans can be used in tracking the efficacy of treatment; for instance, monitoring the efficacy of chemotherapy.

3. Post-treatment follow-up imaging exams: These are done after the treatment has elapsed to ensure if there is a recurrence of cancer.

4. Evaluating Other Diseases: Though PET CT scans are mostly used in cancer, they can also help diagnose and follow up heart disease and neurological disorders.

 

How Often Should You Get a PET CT Scan?

For many patients, getting a PET CT scan whole body scan could be done once every one to two years. However, the frequency would often depend on a patient's individual situation, including their kind and stage of disease. For cancer patients, for instance, the frequency of PET CT scans often depends on the type and stage of their cancer:

 

1. Type and Stage of Disease

  1. Primary Diagnosis: PET CT scan whole body can be done to confirm the existence of cancer.
  2. Follow-up Evaluation: Subsequently, follow-up will likely be recommended through multiple scans every quarter or some years.
  3. Extended Surveillance: Intervals may become less frequent, such as annually depending on a patient's risk factor in the prolonged period of follow-up from the initial treatment.

 

2. Treatment Guidelines

  1. The frequency of scanning can also be depended upon the type of treatment you are undergoing:
  2. Aggressive Treatments: If a person is on aggressive therapies where the line of treatment is as intense as a high dose of chemotherapy, then the doctors would only space out the time between scans to almost a few months without really missing something.
  3. Stable Treatments: When there is no alteration or significant change in a stable treatment plan, then patients are scanned less often.

 

3. New Symptoms

If you ever start experiencing some new or weird symptoms, it is extremely imperative to visit a doctor. Then your health provider could prescribe a PET CT scan at whatever time of their judgment, depending on the changes observed.

 

4. Doctor Advice

Your doctor will personalize a plan for your scanning, depending on your condition. You should really obey that advice since they are able to know everything that is affecting your health, even your medical history and the current treatment status.

 

Risks and Precautions

PET CT Scan of whole body scans are considered generally safe procedures; however, there are some points to be noted. Some risks associated with PET CT scans are as follows:

  1. Radiation Exposure: While PET CT scans expose a patient to some radiation, in general, the dose is quite low. The benefits in an accurate diagnosis and monitoring treatment makes the risks because of exposure less.
  2. Allergic Reactions: There is a minimal possibility for a patient to react allergic through the radioactive tracer that is applied during the scan. It is always imperative that you are aware of any allergies that you may have and inform the doctor before the procedure.
  3. Pregnancy and Breastfeeding: If you are pregnant or a nursing mother, you should communicate this with your physician, since other imaging options will be suggested in order to prevent risk exposure during medical test procedures.
