A Nordic survey of CT doses in hybrid PET/CT and SPECT/CT

PET/SPECT molecular neuroimaging. PET and SPECT have made a significant contribution for many years as to evaluate the physiological function and biochemical changes of molecular targets. Both techniques are based on the measurement of the radionuclide’s decay, during which a positron or a γ-ray will be emitted and thus generate photos. The functional data comes from one of three modalities, PET, SPECT or functional Magnetic Resonance imaging (fMRI). Both PET and SPECT are based on detection of radioactive substances called tracers that are injected into patient.

The SPECT/CT protocols are a set of clinical applications for review and analysis of SPECT/CT studies. Separate applications are provided for General, Prostacint, WBC, Somatostatin, Parathyroid, and Extremities, each with optimized settings for scaling, color and layouts. Up to 4 SPECT/CT scans can be loaded simultaneously for comparison purposes.

Basic principle of PET and SPECT. PET and SPECT are imaging techniques in which a radionuclide is synthetically introduced into a molecule (a ligand, peptide, antibody or antibody fragments etc) of potential biological relevance/interest and administered to an animal or a patient. When the radiotracer is injected into the studied subject, the Se hela listan på digirad.com SPECT, en förkortning av »single photon emission computed tomogra-phy», är en teknik som kan användas bl a för tredimensionell avbildning in vivo av fördelningen av radioaktivt märkta substanser i ett organ, t ex hjär-nan. SPECT är, liksom positronemis-sionstomografi (PET), en avbildning av organet baserad på emitterad gamma- PET/CT bör göras efter avslutad behandling.

The detectors in the PET scanner measure these photos to create images of internal organs. PET Scan Images are Clearer For basic research, PET is the more flexible tool, because innovative tracers are more easily synthesised for PET than for SPECT.

Procedures such as X-rays; computed tomography (CT); magnetic resonance imaging (MRI); positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are important in clinical decision-making, including therapy and follow-up.

ADVANTAGES OF SPECT Improved contrast and reduced structural noise, due to elimination of overlapping structures (compared to planar imaging). Localization of defects is more precise and more clearly seen. Extent and size of defect is better defined.

When the radiotracer is injected into the studied subject, the Generally, SPECT radiotracers last longer in the patient and are primarily used in cardiology where myocardial stress imaging takes about three to four hours, whereas PET radiotracers emit gamma 2019-12-20 SPECT (Single Photon Emission Computed Tomography) and PET (Positron Emission Tomography) are both highly efficient cardio imaging technologies that various facilities use.
