Single Photon Emission Computed Tomography (SPECT); Positron Emission Tomography (PET). When is Nuclear Medicine Used? Your doctor may use a nuclear

In contrast to PET, single photon emission computer tomography (SPECT) instead of positron emitter uses radiopharmaceuticals labelled with gamma emitters with different gamma energies (like 99mTc or 123I) . SPECT also enables three dimensional imaging and there are today also hybrid SPECT/CT scanners available. Typical procedures are bone scans

Nuklearmedicinsk undersökning (NM) och SPECT. Nuklearmedicin NM, (2D) eller SPECT , Single photon emission Tomography (3D) är en undersökningsmetod som visar de fysiologiska funktionerna i organ eller vävnadselement. Undersökningen sker med hjälp av injektion av ett spårämne, en radionuklid, vanligen 99-Tc, 123-I och 111-In 133-Xe.

It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information. PET and SPECT Single photon emission computed tomography (SPECT) imaging is routinely used and is the primary functional imaging tool used to evaluate the heart. More recently, positron emission tomography (PET) has been applied to the study of the heart and its uses continue to expand.

Single-photon emission computed tomography, förkortad SPECT, är en apparat som ger tredimensionella medicinska bilder av olika funktioner i kroppen. Den används vid medicinsk diagnostik. Den använder sig av en eller flera gammakamerahuvuden för att registrera gammastrålning från en injicerad radionuklid i patienten.

For basic research, PET is the more flexible tool, because innovative tracers are more easily synthesised for PET than for SPECT. In addition, the spatial resolution of PET is better than that of SPECT - far better. This is due to the physical nature of nuclear decay of positrons.

SPECT still manages to be the leading choice for cardiac images, although PET is also attracting considerable interest. PET (positron emission tomography) and SPECT (single photon emission computed tomography) are two of the main imaging methods used in nuclear medicine for visualizing the way a … A major difference between PET and SPECT is that SPECT only requires single gamma rays, while PET requires two gamma rays, released in opposite directions.

SPECT es similar a PET en su uso de un material radiactivo como marcador, y la detección de rayos gamma. En contraste con PET, los marcadores usados en SPECT emiten radiación gamma que se puede medir directamente, mientras que los marcadores de PET emiten positrones que se aniquilan con electrones que tienen a unos milímetros, produciendo dos fotones gamma que se emiten en direcciones opuestas.

Die SPECT wird als diagnostische Untersuchung und zur Vorbereitung eines neurochirurgischen Eingriffs auch in der Neuroonkologie eingesetzt. Die SPECT gehört wie die Positronen-Emissions-Tomographie (PET) zu den funktionellen bildgebenden Verfahren, das heißt, die erzeugten Schnittbilder geben Aufschluss über Stoffwechselabläufe des Körpers.

SPECT-teknikken gir en tredimensjonal fremstilling av det aktuelle organet man undersøker. The Albira SI from Bruker provides fully integrated PET/SPECT/CT in a compact footprint. This preclinical SPECT system enables the study of dynamic biological processes. SPECT versus PET • PET delivers absolute activity, but appropriate radionuclides with multiple-day half lives are hard to find. • SPECT probably needs at least attenuation correction. This correction, in turn, probably requires a multi-modality (PSPECT/CT) imager or SPECT-CT registration. SPECT a PET. SPECT a PET jsou jako sestry, v mnohém jsou si podobně a zároveň odlišné.

PET Scan Images are Clearer SPECT is an imaging technique similar to PET that uses radioligands to detect molecules in the body.
