Molecular imaging, including fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET), offers sensitive detection of cancers and monitoring of treatment response. Advanced techniques like MR spectroscopy and SPIO particles show promise for specific cancer evaluations.

Area of Science:

  • Molecular imaging
  • Biomedical imaging technologies

Background:

  • Molecular imaging visualizes cellular biochemical processes with high sensitivity and specificity.
  • Fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) is the predominant molecular imaging technique for body imaging.
  • FDG PET is crucial for staging and restaging common cancers and monitoring therapeutic drug response.

Purpose of the Study:

  • To review current molecular imaging techniques in body imaging.
  • To highlight the utility of FDG PET in oncology.
  • To discuss emerging PET and MR imaging agents and techniques.

Main Methods:

  • Review of current literature on molecular imaging techniques.
  • Focus on fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET).
