PET in Comparison with Other Modalities

Cancer is one of the leading causes of morbidity and mortality worldwide. Various imaging modalities like computed tomography (CT), ultrasonography (USG), magnetic resonance imaging (MRI) based on anatomic information play a vital role for the management of cancer patients; however, they have a notable limitation of inability to identify morphologically normal but functionally abnormal tissues. This limitation is overcome by functional imaging modalities such as Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). Fusion imaging in form of PET-CT has integrated the functional and morphological information in one investigation and has emerged as one of the most useful modality in practice of oncology. It has changed dramatically the management of numerous cancers and its impact has been felt worldwide.
