  • Involves a small amount of radioactive material.
  • This material is called a radiotracer.
  • Radiotracer is injected or ingested by the patient.
  • Special detectors capture emissions from radiotracer.
  • Provides images showing tissue function and metabolism.

Preparing for Your PET Scan: Tips and Information

Here is the basic preparation before, during, and after PET Scan for any patient.

 

Before the PET Scan:

  • Consultation: Schedule the PET scan and discuss your medical history, allergies, and any concerns with your healthcare provider.
  • Fasting: Follow any fasting instructions provided by your healthcare team. Typically, you'll need to fast for several hours before the scan, usually overnight.
  • Medications: Inform your healthcare provider about all medications you are taking, as they may affect the scan. You may need to adjust your medication schedule.
  • Allergies: If you have known allergies to any substances used in the scan, such as contrast agents, inform your healthcare provider in advance.

 

During the PET Scan:

  • Injection: You will receive a radioactive tracer (often through an IV) before the scan. This tracer helps create detailed images of the inside of your body.
  • Waiting Period: After receiving the tracer, there may be a waiting period for it to distribute within your body before the actual scan.
  • Positioning: You'll be positioned on the PET scanner table, and the scanner will move slowly over the area of interest.
  • Communication: You can communicate with the healthcare team if you have any questions or concerns during the procedure.

 

After the PET Scan:

  • Recovery: Typically, there is no special recovery needed, and you can resume your normal activities immediately.
  • Hydration: Drinking fluids can help eliminate the radioactive tracer from your body. Follow any hydration recommendations from your healthcare team.
  • Results: Your PET scan results will be reviewed by a specialist, and a report will be sent to your healthcare provider.
  • Follow-Up: Schedule a follow-up appointment with your healthcare provider to discuss the PET scan results and any further steps or treatments if needed.

Please note that the specific instructions and procedures can vary based on your medical condition and the type of PET scan you are undergoing. Always adhere to the guidance provided by your healthcare team for a successful and safe PET scan.

 

Who Performs a PET Scan?

Professional Role
Nuclear Medicine Technologist Administers radioactive tracers, operates PET scanner.
Radiologic Technologist Assists during the procedure.
Radiologist Interprets PET scan images, provides a diagnosis.

 

PET Scan Procedure

The procedure for PET Scan typically follows these steps:

  • Check-in and registration at the PET scan department.
  • You may be asked to fast for several hours before the scan (typically 4-6 hours).
  • A radioactive tracer, usually FDG (fluorodeoxyglucose), is injected intravenously or administered orally.
  • You'll wait for about 30-60 minutes to allow the tracer to distribute in your body.
  • You'll be asked to empty your bladder before the scan.
  • You'll lie down on an examination table in a quiet room.
  • The PET scanner, a large ring-shaped machine, will slowly move over your body.
  • The scanner detects signals emitted by the radioactive tracer.
  • You'll need to remain as still as possible during the scan, which can take 30-60 minutes.
  • You may be asked to hold your breath briefly for certain images.
  • The procedure is painless, but it's important to relax and avoid movement.
  • After the scan, you can resume normal activities and eating.
  • The images are interpreted by a radiologist or nuclear medicine physician.
  • You may receive the results during your visit or at a later time.

 

PET Scan Results

Here are some common elements you might find in a PET Scan report:

PET Scan Findings Interpretation
Area of Imaging (e.g., brain, chest, etc.) Normal or Abnormal
Standardized Uptake Values (SUV) Quantitative measurements of radiotracer uptake, if applicable
Metabolic Activity Assessment of increased or decreased metabolic activity
Radiotracer Distribution Information about the distribution pattern of the radiotracer
Impression Summary of key findings or diagnostic impressions
Recommendations Follow-up tests, treatments, or further evaluation, if necessary
Conclusion Final remarks or clinical recommendations

PET scans are often used to assess metabolic activity and detect abnormalities in various tissues and organs. The results are typically discussed with the healthcare provider, and any abnormal findings would prompt further evaluation and management based on the clinical context.

 

PET Scan Abnormal Result

Here are potential causes of abnormal PET scan results:

Abnormal PET Scan Finding Potential Causes
Increased Metabolic Activity Cancerous tumors, infection, inflammation, metabolic disorders
Decreased Metabolic Activity Areas of tissue damage, decreased blood flow, necrosis
Altered Radiotracer Distribution Abnormal tissue growth, lesions, infections
Asymmetry in Activity Benign tumors, structural abnormalities, positional differences
Unusual Focal Uptake Lesions, focal infections, granulomas
Impaired Clearance Kidney or liver dysfunction, metabolic disorders

Abnormal PET scan findings require further evaluation by a healthcare provider or specialist to determine the underlying cause and appropriate next steps for diagnosis and treatment. PET scans are valuable for assessing metabolic activity and identifying areas of concern in the body.

 

How Long Does a PET Scan Take?

The duration of a PET (Positron Emission Tomography) scan can vary based on the specific procedure being performed. Here's a general overview of the approximate time it takes for different types of PET scans:

PET Scan Procedure Duration
Whole-Body PET Scan 30 minutes to 1 hour
Brain PET Scan 30 minutes to 1 hour
Cardiac PET Scan 2-3 hours (including rest and stress phases)
FDG-PET/CT Scan (commonly used) 1-2 hours
FDG-PET/MRI Scan (less common) 1-2 hours
  • Please note that these are approximate times and can vary depending on factors such as the type of radiotracer used, the patient's specific condition, and the imaging equipment's capabilities.
  • Additionally, some PET scans may require additional preparation time, such as allowing the radiotracer to circulate in the body before imaging.
  • Always follow the instructions provided by your healthcare provider for your specific PET scan.

PET Scan FAQ

What is a PET scan?

A PET scan, or Positron Emission Tomography, is a medical imaging technique that uses a small amount of radioactive material and a special camera to visualize and assess various processes within the body. It provides detailed information about organ function and can detect abnormalities on a cellular level.

How does a PET scan work?

PET scans work by injecting a radioactive tracer into the patient's body, which emits positrons that interact with electrons in the tissues. These interactions produce gamma rays, which are detected by a PET scanner to create images of the body's metabolic activity.

What are the common uses of PET scans?

PET scans are commonly used to detect and diagnose cancer, assess cancer staging, monitor cancer treatment effectiveness, evaluate heart conditions, and study brain disorders like Alzheimer's disease.

Are PET scans safe?

PET scans are generally considered safe. The amount of radiation used is small and unlikely to cause harm. However, it's important for pregnant women to inform their healthcare provider before undergoing a PET scan.

How do I prepare for a PET scan?

Preparation may include fasting for several hours before the scan and avoiding strenuous physical activity. You should inform your healthcare provider about your medical history, medications, and allergies.
