- SPECT scans are mostly used to perform thyroid imaging, infection (leukocyte) imaging, tumor imaging, or bone scintigraphy. In this scan, radioactive tracers and a scanner are utilized to record data that is then converted into two- or three-dimensional images. As SPECT allows accurate localization in 3D space, its application in brain and cardiac imaging has increased significantly.
- PET scans are extensively applied in clinical oncology and for clinical diagnosis of specific diffuse brain disorders such as various kinds of dementias. The efficiency of this scanning technique in drug development is propelling its application remarkably in the pharmaceuticals, biotechnology, and life science sectors.
