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.
