Despite its advantages, PET also has some limitations:
Limited Spatial Resolution: PET has lower spatial resolution compared to other imaging techniques like CT or MRI, which can make it challenging to precisely localize small lesions. False Positives/Negatives: Inflammatory processes or infections can cause false-positive results, while some low-metabolism tumors might lead to false negatives. Cost and Availability: PET scans are relatively expensive and may not be readily available in all medical facilities. Exposure to Radiation: Although the radiation dose from a PET scan is generally low, it is still a consideration, especially for certain patient populations.
