Animal Scans


The Crump Institute's Preclinical Imaging Technology Center provides state-of-the-art in vivo imaging technologies and related services to UCLA faculty, staff and students, as well as contract work with the non-UCLA community. The Center functions both as a shared preclinical imaging resource for researchers and laboratory facility for imaging research and technology development.

We offer full-service in vivo microPET, microCT and optical imaging and complementary in vitro/ex vivo assays to measure tissue function and structure. Companion PET tracer radiochemistry and radiolabeling services are available in-house and is supported by two on-campus cyclotron facilities. Training in imaging and staff assistance are offered regularly to all users. Study design, development and quotes are provided free of charge. Contact Dr. Jason T. Lee directly at to get started.
