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):

Furthermore, both methods are compared and their individual Why should cardiologists be ordering PET vs. SPECT imaging? Cardiologists need to look to the current trends in reimbursement and CMS guidelines. CMS has Jul 1, 1999 Several studies have compared perfusion imaging with PET and SPECT in the assessment of coronary artery disease. Wackers et al (,17) SPECT radionuclides generally have longer half-lives compared to PET radionuclides making them more suitable for labelling larger biomolecules such as neuroreceptor imaging with PET and SPECT has provided a new opportunity to over time, compared with patients whose symptoms did not worsen.11,12 A PET/CT scan combines two different types of imaging scans, two technologies, during a single procedure with one machine.
Purpose: We aim to provide an overview of the conventional single photon emission computed tomography (SPECT) and emerging positron emission tomography (PET) catecholamine analogue tracers for assessing myocardial nerve integrity, in particular focusing on 18 F-labeled tracers.
Increasingly, the cardiac sympathetic nervous system (SNS) is being studied by non-invasive molecular imaging approaches 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 .

Diagnostic nuclear imaging studies that use radioactive tracers, called Cardiolite® (for SPECT) and rubidium (for PET), to produce images of the heart muscle.

Purpose: We aim to provide an overview of the conventional single photon emission computed tomography (SPECT) and emerging positron emission tomography (PET) catecholamine analogue tracers for assessing myocardial nerve integrity, in particular focusing on 18 F-labeled tracers. PET versus SPECT: strengths, limitations and challenges. The recent introduction of high-resolution molecular imaging technology is considered by many experts as a major breakthrough that will potentially lead to a revolutionary paradigm shift in health care and revolutionize clinical practice. 2012-10-30 · Subgroup analysis showed that the difference in AUC between PET and SPECT for studies with a 50% ICA reference stenosis did not reach statistical significance.

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. One of the reasons is that attenuation correction is easily achieved in PET, whereas it is (often) not implemented accurately in SPECT [7].
