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 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 .

  • September 8, 2014Quantifying absolute MBF in dynamic SPECT

    It is accepted within the cardiology community that measurements pertaining to absolute myocardial blood flow (MBF) and myocardial flow reserve (MFR) provide additional information about a patient’s heart condition than general perfusion. Researchers are still perfecting a standard procedure for obtaining these measurements, but they seem to be getting close in the case of dynamic SPECT, according to a study published Sept. 4 in the Journal of Nuclear Medicine .

  • September 5, 2014New Autofluorescence Imaging Platform Detects and Tracks Bacteria in Chronic Wounds

    Chronic wounds are a significant burden to patients, health care professionals, and health care systems worldwide. Diagnosis of wound infection currently relies on clinical judgment, which varies widely and is subjective in nature, as well as culture-based tests, which can take days to yield results. This can lead to inappropriate use of empiric antibiotics, which is an increasing healthcare concern due to the emergence of drug resistant microbes. Thus, there is a need for better methods of early wound diagnosis and treatment guidance.
