PET CT Scan in Bangalore

What is a PET CT scan?

A PET CT scan is a powerful scan that takes pictures of your entire body to help diagnose and stage cancer. The CT scan takes a series of images of the whole body and converts them into a 3 D shape for better understanding of the body's internal organs. The PET scan uses low-dose radiation to assess the activity of the cells. The combination of a PET scan and CT scan is called a PET CT scan. Cancers cells have much higher activity than the normal cells and hence show up better on the PET CT scan. For a PET scan in Bangalore consult the best cancer hospital near you.

Why am I undergoing PET CT scan?

You may be asked to undergo a PET CT scan because your doctor might suspect cancer.

If cancer is diagnosed, then PET CT scan will help identify the extent of cancer and whether cancer has reached to any other parts of the body as the treatment may change significantly depending upon the spread of cancer and the organs involved.

PET CT scan is also done to plan radiotherapy treatments accurately.

PET CT scan can be used to assess response to treatment and to see if the treatment is working well or not.

You will be required to be fasting for at least 6 hours before your PET CT scan appointment.

The RBS should be less than 150 mg/dl after 6 hours of fasting for you to undergo the PET CT scan.

The PET CT scan is not painful. You will first be given an injection containing low dose radioactive glucose in one of your veins. After the injection, you will be requested to rest in a dark room for about 45 to 60 minutes. You will need to lie down on the bed of the scanner, and multiple X-Rays will be taken by the scanner of your body over the next 30 minutes or so. You will most likely be alone in the room, but the radiographers will be watching you from outside. Once the scan is completed satisfactorily, you will be asked to leave the room. Occasionally, you may be called back again for taking more images or for doing a delayed scan depending upon your requirements.

After the scan is completed and given, okay, yoinu can go home. Please drink plenty of water and liquids throughout the day.

If the results are urgent, then your doctor can get the results by directly speaking to the department.

PET is an abbreviation for Positron Emission Tomography. It uses radiation or nuclear medicine imaging to create three-dimensional colour images of the functional activities within the human body.

A Computed Tomography (CT) scan shows the structure. Combining these two scans into a single advanced PET/CT imaging technique gives detailed information about the existence or spread of disease and accurately identifies its specific locati

It is a procedure that involves injecting a radiotracer (radioactive glucose) into the veins of a patient's arm. The radiotracer will travel through the body and get absorbed by the tissues or organs which are to be studied. Then using high-tech machines or devices, the energy given off by the tracer is converted into a 3-D image.

A PET scan is used to know about the energy changes at the cellular level. It also detects small malignancies, differentiates between benign and malignant tumors, and also allows accurate staging. On the other hand, CT or MRI will identify structural organ or tissue changes that grow at a later stage.

  • Drink fluids to ensure urinating and clearance of the radioactive fluorodeoxyglucose (FDG). 
  • After the scan, you can drive and resume your daily activities.

A PET-CT scan helps your physician in the following ways :

  • To identify disease in its initial stages, often before the patient becomes symptomatic especially when other diagnostic tests are likely to give negative results.
  • Examining the extent and severity of the disease.
  • To tailor the therapy on an individual basis based on the findings of the PET-CT scan report.
  • Evaluate the effectiveness of a treatment regimen.
  • Modify treatment plans in response to the altered biological behaviour of the tissue.
  • Assess disease progression.
  • Identify recurrence of disease and help manage the condition.
