Nuclear Imaging

Molecular imaging, also called nuclear imaging, includes positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. This section includes radiopharmaceuticals and tracersPET-CTSPECT-CT, and PET-MRI

PET, neuroinflammation, multiple sclerosis, MS, Adam Rosenberg, SNMMI 2016

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.

Comparison of Ga-68-DOTATOC PET/CT with Y-90 DOTATOC PET/CT. Although the positron associated with Y-90 is rarely emitted, there is still sufficient signal to acquire a quantitative PET/CT image of Y-90 DOTATOC after a therapeutic administration. The white arrows indicate kidneys and the yellow arrows tumor.

VASH collimator, DOE, molecular breast imaging, SNMMI 2016

Adding this variable angle slant hole collimator to an existing breast molecular imaging system allows the system to get six times better contrast of cancer lesions in the breast, providing the same or better image quality while also potentially reducing the radiation dose to the patient by half. Technologies developed at DOE’s Jefferson Lab for the variable angle slant hole collimator are included in two filings to the U.S. Patent and Trademark Office. Image courtesy of DOE’s Jefferson Lab.

A PET-CT head and neck cancer scan showing various image reconstructions

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.
