Single Photon Emission Computed Tomography in Alzheimer's Disease
Archives of Neurology, 1989To the Editor. —We would like to comment on the article by Johnson et al 1 that appeared in the April 1988 issue of theArchives. 1 The authors reported that single photon emission computed tomography (SPECT) brain imaging with iofetamine hydrochloride I 123 was able to reflect dementia severity in patients with Alzheimer's disease (AD).

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
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.

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 ...

Single-photon emission-computed tomography (SPECT)
1998Abstract Although the principles of single-photon ennssioncomputed tomography (SPECT) have been well understood for many years and several centres were using SPECT clinically in the late 1960s and early 1970s, there has been a dramatic increase in the number of SPECT installations in recent years. In the early 1980s, however, SPECT was a

Single-Photon Emission Computed Tomography (SPECT)
2003Single-photon emission computed tomography (SPECT) is a nuclear medicine technique that provides tomographic images of the distribution of radiopharmaceuticals in the body. Radiopharmaceuticals have been developed to image cerebral perfusion as well as a wide range of brain neurotransmitter systems, especially the dopamine system.

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 Endocrinology
Seminars in Nuclear Medicine, 2006The introduction of fusion of functional and anatomical imaging modalities into the field of endocrinology led to a major breakthrough in diagnosis, staging, and follow-up of patients with endocrine tumors. The management of endocrine tumors is based on a wide variety of conventional techniques, including computed tomography, ultrasound, or magnetic ...

Single Photon Emission Computed Tomography
2006Conventional gamma cameras provide two-dimensional planar images of three-dimensional objects. Structural information in the third dimension, depth, is obscured by superimposition of all data along this direction. Although imaging of the object in different projections (posterior, anterior, lateral, and oblique) gives some information about the depth ...

Positron emission tomography and single photon emission computed tomography
Current Opinion in Neurology, 1996Neuroimaging techniques have had a dramatic impact on the evaluation and treatment of patients with epilepsy. In order to take full advantage of their potential, it is important to place them in clinical and electrophysiological context and to understand their technical limitations. Positron emission tomography with 18F-2-deoxyglucose and single photon
