PET Imaging
Positron emission tomography (PET) is a nuclear imaging technology (also referred to as molecular imaging) that enables visualization of metabolic processes in the body. The basics of PET imaging is that the technique detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (also called radiopharmaceuticals, radionuclides or radiotracer). The tracer is injected into a vein on a biologically active molecule, usually a sugar that is used for cellular energy. PET systems have sensitive detector panels to capture gamma ray emissions from inside the body and use software to plot to triangulate the source of the emissions, creating 3-D computed tomography images of the tracer concentrations within the body.

A PET-CT head and neck cancer scan showing various image reconstructions. The top left image is the separate CT scan showing the anatomy. The top right scan shows the fused PET and CT scans with false color added to help interpret the image. The bottom left scan is an initial FDG PET image showing tracer hot spots in the neck and a lymph node in the right jaw due to cancer. The right bottom image is a delayed enhancement scan showing tracer uptake over time, with normal hot spots in the bladder, kidneys, testicles and brain, which normally have higher metabolic activity. The low-grade gray shading of the anatomy is due to the normal cellular metabolism uptake of the FDG throughout the body.

A. Increased F-18 TZ3504 uptake was observed in the inflamed lumbar spinal cord of EAE-treated animals in the rat model of MS compared to sham control rats. Representative sagittal, coronal and transverse views of the thoracic and lumbar spine are shown. B. The time activity curve of F-18 TZ3504 uptake in the lumbar spinal cord was significantly higher for the first 30 minutes in EAE-treated rats. C. F-18 TZ3504 was able to cross the blood brain barrier and showed homogeneous distribution in the brain of a healthy nonhuman primate.
