Position Emission Tomography – Computer Tomography (PET/CT) is a diagnostic test that acquires images from both the PET and CT in the same session and lays one image over the other to create a single image. The metabolic activity measured by the PET scan is precisely aligned with the images obtained by the CT scan, and combined, it provides a detailed 3-D anatomical image.
These 3-D functional images are used to evaluate a variety of diseases, including:
- Cancers in the lung, colon and rectum, skin (melanoma), head and neck, esophagus, breast, cervix, ovaries, pancreas, testes, and thyroid
- Lymphoma (e.g. Non-Hodgkin’s and Hodgkin)
- Soft Tissue Sarcoma
- Solid tumors
- Brain Perfusion (e.g. Alzheimer’s)
