Single-photon emission computed tomography (SPECT) uses radioisotope-labeled tracers that are injected into or ingested by the subject. The radiation is measured and can be imaged in 3-D.
microSPECT is a specialized version of SPECT that creates the high-resolution images necessary to image small animals. This imaging technique is used to monitor the distribution of treatments and probes as they circulate through a living body. Treatments can be labeled with radioactive particles, which broadcast their location to the SPECT machine. This capability allows experiments to be designed so the same animals can be used throughout the experiment, thereby reducing the burden on the animals and decreasing uncertainty in the results.
