SPECT) and random coincidences (in PET) are ad-dressed in the next, two sections.

PET and SPECT scans use radiopharmaceuticals to create 3D images, but the tracers used are differently. SPECT scans measure gamma rays, and the radiotracers used with PET scans produce small particles called positrons. The detectors in the PET scanner measure these photos to create images of internal organs. PET Scan Images are Clearer. PET scan images are generally reported to offer a higher resolution of 5 to 7 mm, compared with a cardiac SPECT scan resolution of 12 to 15 mm.

SPECT) Single-photon emission computed tomography (SPECT): is lower cost; uses gamma emitting radioisotope (tracer): technetium-99m; iodine-123; iodine-131 Se hela listan på digirad.com PET and SPECT scans use radiopharmaceuticals to create 3D images, but the tracers used are differently. SPECT scans measure gamma rays, and the radiotracers used with PET scans produce small particles called positrons. The detectors in the PET scanner measure these photos to create images of internal organs. PET Scan Images are Clearer.

SPECT is now a cornerstone with any patient with heart disease. At the same time, some published results suggest that PET may offer increased accuracy and improved sensitivity compared to SPECT [5,6], particularly for heavier patients, where breast, chest wall and diaphrag-matic attenuation interfere with conventional SPECT.

However it lacks good spatial (i.e., where exactly the particle is) or temporal (i.e., did the contrast agent signal happen at this millisecond, or that millisecond) resolution. 2014-11-11 · SPECT and 18F-FDG PET differ in the equipment needed, im-age characteristics, availability, and patient experience.

Option 3  SPECT is much more widely available than PET. It’s also much more affordable, with the average camera costing between $400,000 and $600,000. Due to its widespread use, there are more trained technologists available too. The longer half-life of the SPECT radiotracer makes it more widely available and is ideal for cardiac stress testing. 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. Positron emission tomography (PET): SPECT has a wider range of circulation than PET which also makes it more affordable with an average cost of $500,000. The worldwide usage of technology also indicates that there is more trained personnel available. Ideal ford cardiac stress testing with the expectation to boost image quality.

It is not the intent of this book to present an in-depth explanation of nuclear medicine technology. The discussion will include only a brief introduction into the world of nuclear medicine and the use of single photon emission computed tomography (SPECT) and positron emission tomography (PET).

Diagnostic accuracy in identifying cardiac coronary artery disease for PET and SPECT is 95% and 83% respectively. SPECT is now a cornerstone with any patient with heart disease. At the same time, some published results suggest that PET may offer increased accuracy and improved sensitivity compared to SPECT [5,6], particularly for heavier patients, where breast, chest wall and diaphrag-matic attenuation interfere with conventional SPECT.

The final method is positron emission tomography (PET). This involves injection of a different type of radiotracer, one which emits positrons (positively charged electrons). Cardiac SPECT vs PET Increasingly, cardiologists prefer cardiac PET scans to SPECT scans for the following reasons: PET scans offer a higher spatial resolution and accuracy than SPECT scans. Diagnostic accuracy in identifying cardiac coronary artery disease for PET and SPECT is 95% and 83% respectively. This represents the major advantage of SPECT as a molecular imaging technique, since it is significantly cheaper than either PET or fMRI. However it lacks good spatial (i.e., where exactly the particle is) or temporal (i.e., did the contrast agent signal happen at this millisecond, or that millisecond) resolution.
