Positron Emission Tomography and Computed Tomography Information Powerpoint

Positron Emission Tomography (PET) and CT Scan Presentation

By: Harry H. Holdorf

PET CT image

This presentation discusses Positron Emission Tomography/Computed Tomography (PET/CT), a medical imaging technique using a device which combines two scan techniques into one, Positron Emission Tomography (PET) and Computed Tomography (CT). The images can be taken sequentially from the patient in the same session and then combined into a single superimposed image. The two procedures together provide information about the location, nature, and extent of a lesion. This Powerpoint will also discuss the role of PET/CT in:

  • Oncology
  • Cancer Treatment & Prognosis
  • Neurology
  • Cardiology
  • Advantages & Disadvantages
  • Radiation Dose Comparison
