Metabolic Biopsy through PET-CT

  • Going further the CT-guided biopsy, this procedure involves a biopsy under the guidance of PET-CT imaging
  • Since PET imaging demonstrates metabolic activity of the lesions, the biopsy needle is then specifically targeted to the most active site within the tumour, this ensuring to get enough viable tissue for histopathology studies
  • The tissue yield is the highest with this image guidance
  • In certain specific sites like liver, the lesion may not be apparent on a plain CT scan for the biopsy. In such cases, the PET still demonstrates the abnormal focus of activity, which can again be targeted for a biopsy.
