Understand the limitations of a PET scan for cancer. Learn what factors can affect the results and accuracy of this imaging test in oncology.
Overview
Unlike CT or MRI which provide anatomical information PET imaging evaluates the biological activity of cells. Cancer cells grow and divide rapidly, requiring more energy than normal cells. As a result they absorb larger amounts of the radioactive glucose tracer used during a PET scan. The PET scanner detects these areas of increased activity allowing physicians to identify suspicious lesions throughout the body. Healthcare professionals frequently recommend PET scans before treatment during therapy and after treatment completion. The information obtained from the scan assists in staging cancer, selecting appropriate therapies, monitoring treatment response and detecting the recurrent disease.
What are the Limitations of PET Scan for Cancer?
- Involves exposure to a small amount of ionising radiation.
- Requires injection of a radioactive tracer.
- Some slow-growing cancers may not absorb significant amounts of tracer.
- Infections and inflammation may occasionally produce false-positive results.
- More expensive than many conventional imaging tests.
- Limited availability in some healthcare centres.
- High blood glucose levels can reduce image quality.
- Small lesions below the scanner's resolution may occasionally be missed.
- Additional imaging or biopsy may still be required.
- Results should always be interpreted together with clinical findings and other investigations.
