A PET scan itself usually takes about 30 minutes. However, the entire process, including preparation and waiting time, can take between two and three hours.
PET Scan Duration Breakdown
While the actual scanning portion is relatively quick, there are other time considerations:
- Radioactive Substance Absorption: It takes approximately 30 to 60 minutes for your body to absorb the injected radioactive substance. During this period, you will need to sit quietly and minimize movement.
- Total Time in Department: You should expect to be in the PET imaging department for a total of two to three hours. This accounts for preparation, injection, absorption time, the scan itself, and any post-scan procedures.
Important Considerations
The quoted times are estimates. Factors that may influence the duration include:
- The specific area of the body being scanned.
- The type of PET scan being performed.
- The individual patient's physiology.
