The high prevalence of malignancy associated with focal hypermetabolic thyroid nodules found on F-FDG-PET warrants further evaluation when detected.

It remains inconclusive whether FDG-PET or bone scintigraphy is superior in detecting osseous metastasis from breast cancer. However, FDG-PET does have a higher specificity and may better serve as a confirmatory test than bone scintigraphy and used to monitor response to therapy.

Colorectal cancer is commonly diagnosed in the United State and is one of the leading causes of cancer deaths. Positron emission tomography has been used for the evaluation and management for patients with colorectal cancer. Frequently, abnormal incidental lesions are detected on positron emission tomography. This article will review current literature for the prevalence of malignancy and pre-malignancy in incidental focal hypermetabolic colorectal lesions detected by positron emission tomography and briefly discuss its clinical impact.
