SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]
Gated SPECT is a nuclear medicine imaging technique, typically for the heart in myocardial perfusion imagery. [1] An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.
DaT Scan (DaT scan or Dopamine Transporter Scan) commonly refers to a diagnostic method, based on SPECT imaging, to investigate if there is a loss of dopaminergic neurons in striatum. The term may also refer to a brand name of Ioflupane (123I) tracer used for the study.
High resolution 99m Tc-MDP mouse scan acquired with a stationary SPECT system: animated image of rotating maximum intensity projections.. Preclinical or small-animal Single Photon Emission Computed Tomography is a radionuclide based molecular imaging modality for small laboratory animals [1] (e.g. mice and rats).
All nuclear medicine scans give information to the referrering clinician on the function of the system they are imaging. Specific techniques used are generally either of the following: Single-photon emission computed tomography (SPECT), which creates 3-dimensional images of the target organ or organ system. Scintigraphy, creating 2-dimensional ...
Coded aperture mask for gamma camera (for SPECT) Scintigraphy ("scint") is the use of gamma cameras to capture emitted radiation from internal radioisotopes to create two-dimensional [1] images. SPECT (single photon emission computed tomography) imaging, as used in nuclear cardiac stress testing, is performed using gamma cameras. Usually one ...
SPECT is commonly used to diagnose certain diseases. [1] SPECT imaging is conducting by injecting a radioactive probe (or tracer) into the person's blood stream. [1] A 3-dimensional image is produced using cameras that can image radioactive substances as the tracer is absorbed by specific types of body tissue.
Single-photon emission computed tomography (SPECT) is similar to PET and uses gamma ray-emitting radioisotopes and a gamma camera to record data that a computer uses to construct two- or three-dimensional images of active brain regions. [16] SPECT relies on an injection of radioactive tracer, or "SPECT agent," which is rapidly taken up by the ...
