KnowraSingle-photon emission computed tomographyLinked fromLinked fromThe 8 pages that link to Single-photon emission computed tomography, each with the reason it gives.All 8Broader topic 2Related 3Compared with 3ElectroencephalographyCompared with: SPECT images tracer distribution over longer intervals rather than recording rapid electrical fluctuations.Positron emission tomographyCompared with: SPECT uses single emitted photons, whereas PET detects photon pairs from positron annihilation.NeuroimagingCompared with: SPECT provides tracer-based brain images with different sensitivity and resolution tradeoffs than PET.Nuclear medicineBroader topic: SPECT adds three-dimensional localization to gamma-camera measurements.RadiopharmaceuticalBroader topic: SPECT commonly images gamma-emitting radiopharmaceuticals within organs and tissues.Nuclear isomerRelated: Technetium-99m is a common radiotracer for this imaging method.TechnetiumRelated: SPECT cameras commonly detect gamma rays from technetium-99m tracers.Gamma-ray techniquesRelated: It forms tomographic images from gamma rays emitted directly by radiotracers.
