PET procedures allow for the early discovery of cancers and are useful in following the evolution of any specific cancerous growth. These three images of the same patient taken with a CT (Computed Tomography) scanner and a PET camera show the advantages of these nuclear imaging techniques. While the scanner provides detailed anatomical images but is unable to detect any lesions, the PET images show an abnormal cellular activity in the larynx close to the principal tumour. These tomography techniques allow for three body scans to be taken simultaneously.
