Single-Photon Emission Computed Tomography
2016Single-Photon Emission Computed Tomography (SPECT) is the most widely used nuclear imaging technique in cardiology, playing an important role in the detection of coronary artery disease (CAD), viability assessment, and risk stratification. Myocardial perfusion imaging (MPI) improves the sensitivity and specificity over standard exercise stress testing ...

Single-Photon Emission Computed Tomography/Computed Tomography in Abdominal Diseases
Seminars in Nuclear Medicine, 2007Single-photon emission computed tomography (SPECT) studies of the abdominal region are established in conventional nuclear medicine because of their easy and large availability, even in the most peripheral hospitals. It is well known that SPECT imaging demonstrates function, rather than anatomy.

Single-photon emission computed tomography
Proceedings of the IEEE, 1983The subject of singl-photon emission computed tomography (SPECT) is generally reviewed. The basic interaction processes of gamma rays in matter are outlined, and the formation of conventional gamma-ray images is described. We then outline the extension of these concepts to the formation of three-dimensional or tomographic images.

The Diagnosis of Dementia With Single Photon Emission Computed Tomography
Archives of Neurology, 1987Single photon emission computed tomography is a practical modality for the study of physiologic cerebral activity in vivo. We utilized single photon emission computed tomography and N-isopropyl-p-iodoamphetamine iodine 123 to evaluate regional cerebral blood flow in nine patients with Alzheimer's disease (AD), five healthy elderly control subjects, and

Single-photon emission computed tomography–computed tomography in imaging infection
Nuclear Medicine Communications, 2013This review focuses on the current evidence available on the use of single-photon emission computed tomography-computed tomography (SPECT-CT) in infection imaging. The single-photon functional agents commonly used to image infection include In-111-labelled or Tc-99m-labelled leucocytes, Ga-67 citrate, Tc-99m-biphosphonates and radiolabelled ...

Single Photon Emission Computed Tomography Tracer
2012Single photon emission computed tomography (SPECT) is the state-of-the-art imaging modality in nuclear medicine despite the fact that only a few new SPECT tracers have become available in the past 20 years. Critical for the future success of SPECT is the design of new and specific tracers for the detection, localization, and staging of a disease and ...

Brain single‐photon emission computed tomography *
Neurology, 1994Single-photon emission computed tomography (SPECT) provides cost-effective information on regional cerebral perfusion and, indirectly, on regional cerebral metabolism. Its ease of use facilitates the application of SPECT in clinical neurology. SPECT is emerging as a useful tool for the management of patients with stroke, epilepsy, recurrent brain ...

Bone single photon emission computed tomography
Imaging, 2001Bone SPECT has improved the accuracy of bone scanning.The benefit arises from improvements in contrast and spatial localization.The lumbar spine is the site where the greatest benefit has been demonstrated.Other skeletal sites include knees, hips, base of skull and temporomandibular joints.

Thallium imaging with single photon emission computed tomography
American Heart Journal, 1987Evaluation of myocardial perfusion with thallium-201 SPECT has advantages over planar images. These advantages are related to better contrast of the images, lack of superimposition of normal and abnormal areas, and a three-dimensional representation of the site and extent of perfusion abnormalities (ischemia, scar, or both). For this reason, rotational
