Single photon emission computed tomography (SPECT) and positron emission tomography (PET) are nuclear medicine imaging techniques which provide metabolic and functional information unlike CT and MRI. They have been combined with CT and MRI to provide detailed anatomical and metabolic information Pros and Cons of PET vs. SPECT Technology. The main positives of SPECT scanning are that it's much more available and widely used and much cheaper than PET. A SPECT scanner gamma camera costs $400,000 to $600,000, while a PET-CT scanner can cost around $2 million. While PET is more expensive in terms of purchasing equipment, SPECT radio. PET/CT-Scanner Der Computer erstellt aus den Messdaten des PET-Scanners wiederum ein dreidimensionales Bild, aus dem dann Schnittbilder berechnet werden. Die Qualität und die räumliche Auflösung der Aufnahmen ist jedoch deutlich besser als beim SPECT-Verfahren - unter anderem auch, weil die Tot- und Abklingzeiten der verwendeten PET-Kristalle erheblich kürzer sind. Neuere Geräte nutzen. When it was suggested, during our interview with Dr Torsten Kuwert, Director and Professor of Clinical Nuclear Medicine, Clinic of Nuclear Medicine, at Friedrich-Alexander University Hospital, Erlangen, that SPECT-CT is the little sister of PET-CT, and that he might have preferred to install the 'big brother', Dr Kuwert pointed out the greater cost of PET, explaining: 'The isotopes are.

SPECT Scanner vs. PET, Which is Best? SPECT Scanner DAI

B X-Ray Computed Tomography. X-ray CT is a form of transmission computed tomography that is based on the reconstruction techniques described in Chapter 16. It shares many of the features of transmission scanning that already have been described for attenuation correction for SPECT (see Chapter 17, Section B.3) and PET (see Chapter 18, Section D.4) imaging CT scan (computer tomography) and PET scan (positron emission tomography) are different but related imaging techniques. A PET scan uses nuclear medicine imaging to produce a three-dimensional picture of functional processes in the body. PET scans provide metabolic information and are increasingly read alongside CT or MRI (magnetic resonance imaging) scans, which provide anatomic information

Comparing CT and PET-CT. PET/CT scans provide significantly more information than CT scans, and are far more reliable when diagnosing cancer. The reality is that you cannot rely on a CT scan (or ultrasound, MRI, or blood test) to tell you if you have cancer. It is only with a PET/CT scan that you will know for sure.. PET/CT, which is a combination of positron emission tomography (PET) with. Hierbei scheint die SPECT/CT der MRI häufig überlegen bzgl. der Detektion der Lokalisation der schmerzauslösenden Pathologie, sodass es durch diese Zusatzinformation in einer signifikanten Anzahl der Fälle zu einer Beeinflussung des weiteren klinischen Prozederes kommt (Accuracy / PPV MRI 0.56 / 0.80 vs. SPECT/CT 0.77 / 0.98). Gerade auch bei Statikfehlern im Bereich des oberen oder.

Auch bei der SPECT kommen die bei der PET gebräuchlichen schnell zerfallenden radioaktiven Substanzen als sogenannte Tracer zum Einsatz. Die SPECT erzeugt durch eine besondere Messmethode mit beweglichen Kameras viele Bilder, die ähnlich wie bei der Computertomographie (CT) den Körper in vielen dünn geschichteten Querschnitten zeigen.

Researchers demonstrate that combined PET/CT (right) of a mouse provides a more complete view of the spine than CT (left) or PET (middle) alone. Approved tracers are called radiopharmaceuticals since they must meet FDA's exacting standards for safety and appropriate performance for the approved clinical use. The nuclear medicine physician will select the tracer that will provide the most. Compared with PET/CT, diagnostic CT protocols including intravenous or oral contrast agent enhancement are seldom performed at SPECT/CT but may be appropriate in certain clinical situations (Tables 1 and 2).

Thus, the 2 datasets can be acquired. SPECT vs. PET: SPECT stands for Single Photon Emission Computed Tomography. PET stands for Positron Emission Tomography. The basic idea is that you label a molecule with a radioactive emitter and watch where it goes in the body. You should use a molecule that gets concentrated in a specific type of tissue so that you can get a good picture of that tissue. The technical difference between SPECT. Purpose . The use of SPECT/CT in bone scans has been widespread in recent years, but there are no specific guidelines concerning the optimal acquisition protocol. Two strategies have been proposed: targeted SPECT/CT for equivocal lesions detected on planar images or systematic whole-body SPECT/CT. Our aim was to compare the diagnostic accuracy of the two approaches.<i> Methods</i>. 212. Positron emission tomography (PET) scanning is another type of imaging study, which instead uses radiolabelled glucose as a marker. As neural tissue uses glucose as its fuel, regional cerebral metabolic rate of glucose can be imaged directly using fluorine-18 fluorodeoxyglucose (F-18 FDG). Although FDG-PET has superior resolution to SPECT, its availability in Australia is currently limited. In. As part of the family of nuclear imaging techniques, PET and SPECT scans use small amounts of radionuclides (radioactive isotopes) to measure cellular/tissue change. Radionuclides are absorbed by healthy tissue at a different rate than tissue undergoing a disease process. A deviation in normal rates of absorption may be an indication of abnormal metabolic activity, which could lead to.
