What are Nuclear Medicine and Molecular Imaging?

Molecular imaging is a type of medical imaging that provides detailed pictures of what is happening inside the body at the molecular and cellular level. Where other diagnostic imaging procedures—such as x-rays, computed tomography (CT) and ultrasound—offer pictures of physical structure, molecular imaging allows physicians to see how the body is functioning and to measure its chemical and biological processes.

Molecular imaging includes the field of nuclear medicine, which uses very small amounts of radioactive materials (radiopharmaceuticals) to diagnose and treat disease. In nuclear medicine imaging, the radiopharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures of the area of the body being imaged. Nuclear medicine can also be used to treat certain types of cancer and  other diseases.

Molecular imaging offers unique insights into the human body that enable physicians to personalize patient care. In terms of diagnosis, molecular imaging is able to:

  • provide information that is unattainable with other imaging technologies or that would require more invasive procedures such as biopsy or surgery
  • identify disease in its earliest stages and determine the exact location of a tumor, often before symptoms occur or abnormalities can be detected with other diagnostic tests

  • September 16, 2014Rising to the Occasion: Radionuclide Therapy

    First-order treatment of cancer typically involves chemo and/or radiation therapy and surgical intervention, but radionuclide therapies offer some advantages for select patients by delivering a very intense dose sequestered to affected tumor sites. These are the therapies currently available and in clinical trials, with a few novel compounds waiting for validation in the wings.

  • September 16, 2014Q&A With Barry A. Siegel, MD: SNMMI Cassen Prize Winner

    As the 2014 Annual Meeting for the Society of Nuclear Medicine and Molecular Imaging (SNMMI) came to a close this year in St. Louis, Molecular Imaging Insight sat down with Barry A. Siegel, MD, professor of radiology and medicine and chief of the nuclear medicine division at local Washington University School of Medicine. Siegel was honored this year with the most highly regarded award in nuclear medicine: the Benedict Cassen Prize, presented during the Annual Meeting.

  • September 15, 2014Ga-68 DOTATATE PET/CT finds more NETs

    A comparison study of three different methods of neuroendocrine tumor (NET) detection that includes PET/CT, SPECT/CT and whole body MR imaging places PET/CT with gallium-68 (Ga-68) DOTATATE on a pedestal above the rest for its sensitivity in finding NETs, according to a study published Aug. 28 in the Journal of Nuclear Medicine .
