A PET scan is a medical imaging technique that uses a small amount of radioactive material to visualize and assess metabolic activity in the body, aiding in the diagnosis and monitoring of diseases such as cancer and neurological disorders.
PET scan stands for Positron Emission Tomography.
Here are the basic details for the PET Scan .
|Also Known As||Positron Emission Tomography (PET)|
|Type||Nuclear Medicine Imaging|
|Purpose||Evaluate organ function and detect diseases|
|Preparation||Fasting, avoid strenuous activity|
|Age Group||All age groups|
|Procedure Duration||1-2 hours|
|Reporting Time||Typically within a few days|
|Cost||10,000 - 40,000* INR|
|Pregnancy Consideration||Avoided during pregnancy|
|Risks and Safety||Low radiation, minor risks of allergies|
|Accessibility||Available in specialized centers|
*Price range may vary as per location, facility, type, and procedure.
Here are common reasons for PET Scan.
Here are the types of PET Scan along with their primary use.
|PET Scan Type||Organ/System||Primary Use|
|Whole-Body PET Scan||Whole body||Detect metabolic abnormalities|
|Brain PET Scan||Brain||Assess brain function|
|Cardiac PET Scan||Heart||Evaluate cardiac blood flow|
|FDG-PET/CT Scan||Various||Detect cancer and metastases|
|Gallium Scan||Various||Assess inflammation or tumors|
|Renal Scan||Kidneys||Evaluate kidney function|
|Hepatobiliary Scan||Liver/Gallbladder||Assess liver and bile ducts|
|Lung Ventilation/Perfusion Scan||Lungs||Assess lung function|
|Octreotide Scan||Various||Detect neuroendocrine tumors|
These PET scan types provide valuable insights into specific organs and conditions.
Here is the basic preparation before, during, and after PET Scan for any patient.
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.
|Nuclear Medicine Technologist||Administers radioactive tracers, operates PET scanner.|
|Radiologic Technologist||Assists during the procedure.|
|Radiologist||Interprets PET scan images, provides a diagnosis.|
The procedure for PET Scan typically follows these steps:
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.
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.
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.
Here are some limitation associated with a PET Scan.
Here are some risk factors associated with a PET Scan
|High radiation risk||Low radiation exposure|
|Dangerous for all||Specific medical purposes|
|Harmful for health||Generally well-tolerated|
|Invasive procedure||Non-invasive imaging|
|Risky for children||Used in pediatric medicine|
|Permanent effects||Temporary radiation|
|Not for everyone||Risk assessment considered|
