What are the Limitations of PET Scans in Toxicology?
Despite its numerous benefits, PET scans do have limitations:
Cost and accessibility: PET scans are expensive and not as widely available as other imaging techniques, limiting their use in some research settings. Radiation exposure: The use of radioactive tracers poses a risk of radiation exposure, which must be carefully managed, especially in repeated studies. Tracer specificity: The effectiveness of a PET scan largely depends on the specificity of the tracer used, which can be a limiting factor in detecting certain toxins.
