PET Instrumentation Development Lab Group

The non-invasive visualization of molecular functions and genetic expression can provide valuable information about cancer management. 

Positron emission tomography (PET) has emerged as a powerful diagnostic tool because of its ability to detect the smallest molecular reactions without using invasive techniques. This unique system can advance research on cancer genetic expression, detection and therapy in humans and genetically engineered mice.

The heart of PET is its complex camera system. We have developed and validated ultra-high-resolution, less expensive camera technology that has been adopted commercially for the next generation of PET cameras.


The PET Development Laboratory at MD Anderson Cancer Center strives to:

  • Develop PET systems with spatial resolution significantly better than commercially available scanners for earlier cancer detection and more accurate staging.
  • Develop PET camera with higher sensitivity to reduce scanning time, cost and patient exposure to radiation.
  • Decrease the cost of PET to make its powerful technology more widely available.
  • Develop high-resolution and high-sensitivity small cameras for genetically engineered mouse cancer models to aid in new drug development.
  • Develop dedicated breast PET camera.

The PET Instrumentation Development Laboratory was created in 1993 by Wai-Hoi (Gary) Wong, Ph.D., with funding from the National Institutes of Health. The laboratory, which has grown significantly and continuously being supported completely by NIH grants, is recognized as one of the premier nuclear instrumentation development laboratories in the world.
