Accurate Detection is the key to Cure Cancer!!

What is PET / CT Scan?

PET / CT Scan ( Positron Emission Tomography and Computerized Tomography) is the standard imaging tool that can help physicians locate the exact location of cancer. It helps in early and accurate detection that enables you to take the right treatment decisions at the right time.

The PET scan is a highly sensitive tool that can easily detect the metabolic signals of cancer cells that are actively growing within a person’s body. On the other hand, a CT scan offers precise internal anatomy images that clearly points out the shape, size and location of the cancerous growth. Thus, a combination of PET-CT scan helps in detecting the stage and details of cancer more accurately than any other detection method.

How PET / CT Scan Helps Cure Cancer

The most common use of PET / CT is in the detection of cancer and the evaluation of cancer treatment. Your doctor may use a PET / CT scan to:
  • Diagnoses cancer accurately.
  • Detects the size and spread of cancer (Stage of cancer).
  • Determines whether you need surgery to remove the cancer.
  • Decides which is the best treatment method to be followed.
  • Keeps a tab on whether cancer makes a comeback.
  • Helps to plan the radiotherapy treatment.
Studies prove that the top five cancers account for about 47.2% of cancer in both men and women. These cancers can be easily cured/prevented if they are detected early, diagnosed correctly and treated during the early stages Thus, early and accurate detection has the potential to significantly lower cancer-related deaths.

How Does A PET / CT Scan Work?

  • The doctor injects a radiotracer in your vein. It can also be injected directly to the organ, taken it by mouth or breathed in.
  • The radiotracer will take 30-90 minutes to reach the target (Time varies according to the organ).
  • The organs and tissues will absorb the tracer. As the cancer cells have greater energy, they absorb the tracer more. Hence, they will be highlighted as brighter spots in the scan.
  • The patient has to stay still without talking. Some patients will be given medicines to help them relax.
  • After the patient gets ready, they will be taken to the scanning room and will be asked to lie down on a cushioned scanning table.
  • The table slowly slides inside a large hole, and the patient will be surrounded by the machine. The patient will have to stay as calm as possible during the scan.
  • The machine takes images. Depending on the organ tested, the time can vary up to 30 minutes.
  • The scan is not painful. In case the patient feels any discomfort, they can alert the staff by pressing the buzzer.
  • The entire scanning procedure is completed within 2 hours. The patient can go home immediately after the scan.
