What is a PET CT Scan?

PET – Positron Emission Tomography is a technique that helps to detect and evaluate any disease or abnormality inside your body. It involves the use of a camera and a special dye, having minimal amounts of radioactive materials called radioactive tracers. These are injected, swallowed, or inhaled. The traces get accumulated in those areas of the body in which the level of chemical activities is comparatively higher and the same show as bright spots on the computer screen, which is attached to the camera.

PET scan also superimposes nuclear medicine images with computed tomography (CT) to produce special images. For precise information and accurate diagnoses, doctor associate and interpret information from two different exams on one image. PET/CT units both perform bot the exams at the same time.

To produce multiple images of the inside of the body, CT imaging utilizes x-ray equipment, and in some cases a contrast material. On a computer monitor, these images are viewed by a radiologist. CT imaging provides the user information on anatomic function. Almost, all PET/CT scanners perform all PET scans today.

PET CT scan can be performed to:

  • Determine any abnormality in the otherwise normal blood flow
  • Evaluate your oxygen intake
  • Assess the metabolic activities of your organs and tissues.

PET CT Scan is used to detect the following:

  • Malignancies – Since malignant cells tend to have a comparatively higher metabolic rate as compared to normal cells, these are easily detectable with the help of a PET scan, which also helps to determine how far cancer has spread, whether cancer treatment is effective and if there are any chances of recurrence.
  • Neurological ailments - The tracers get attached to the glucose present in the brain. The imaging guidance technique helps to determine the areas with elevated utilization of radioactive glucose, which is likely to happen in the regions that are not functioning normally.
  • Cardiovascular diseases and disorders – PET scan helps to detect those areas of the heart where the blood supply is lower than normal. Since healthy heart tissues absorb more tracer, it is relatively easy to detect the areas that are not functioning properly.

What are the accepted indications for PET CT Scan?

PET-CT is a blend of the metabolic information provided by positron emission tomography (PET) and cross-sectional anatomic information provided by CT. PET is most generally performed with 2-[F-18]fluoro-2-deoxy-D-glucose (FDG).

Following are the indications for F-18 fluorodeoxyglucose (FDG) PET-CT imaging:

  • Staging of cancer which is treated radically.
  • Establish baseline cancer staging before proceeding for treatment
  • Analysis of an indeterminate lesion
  • Assessing whether therapy is working or not
  • Evaluation of suspected recurrence of disease, relapse and/or residual disease
  • To guide a biopsy

In addition, PET CT is also used as a problem-solving tool:

  • Occult primary lesion such as non-metastatic manifestation of neoplastic disease
  • Evaluation of recurrence of disease in patients with equivocal conventional imaging
  • Assessment of residual disease in patients with treated medullary thyroid carcinoma and differentiated thyroid carcinoma with negative/equivocal conventional imaging
  • Suspicious malignant transformation in plexiform neurofibromata
  • Difference between tumour recurrence and radiation-induced necrosis

What To Expect in a PET CT scan?

Before the PET CT scan Procedure

  • You will be asked to wear a hospital gown. If a woman is pregnant, then she should tell their doctor and technologist about it.
  • You must inform the doctors and the technologist performing your exam about any medications you are taking.
  • The doctors and technologists will give special instructions to prepare for this exam.
  • You will have to leave any metal objects at home.
  • Generally, your doctor will ask you to come empty stomach before a whole-body PET/CT scan.
  • Your doctor will also check you for any medical conditions you may have that could increase the risk of receiving intravenous contrast material.

During the PET CT Scan Procedure

  • For the scan, you will be asked to lie on an examination table. A nurse or technologist will place an intravenous (IV) catheter into a vein in your hand or arm.
  • As PET CT scans only use radiotracer injections, you will be asked to rest quietly and to avoid movement and talking while the radiotracer travels through your body and gets absorbed by the area under examination.
  • During the PET/CT scanning, you will have to lie still. The CT exam will take place first, and then the PET scan is performed.
  • The total scanning time is usually about 30 minutes.

After the PET CT ScanProcedure

  • After the PET CT Scan examination, you will be asked to wait until the technologists check the images for some more images.
  • The intravenous (IV) line inserted for the procedure will be removed after the procedure.
  • A radiologist or other doctor specially trained in nuclear medicine will analyze and interpret the images and share it with you or send them to your physician.

Are there any risks involved with PET CT Scan?

  • A nuclear medicine exam has a relatively low radiation exposure, and thus there are very low risks.
  • Tell your medicine personnel of any allergies beforehand to avoid any complications.
  • Injection of the catheter may cause quiet discomfort.
  • If you are pregnant or breastfeeding, always tell your doctor and radiology technologist beforehand.
