PET (Positron Emission Tomography)

Positron Emission Tomography (PET) and Computed Tomography (CT) imaging are essential diagnostic tools physicians use to reveal the presence and severity of cancers. PET/CT detects cancer, evaluates the extent of disease, selects the most appropriate treatments, determines if the therapy is working, and detects any recurrent tumors.
