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

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

Journal of cardiology. Supplement, 1989Positron emission computed tomography (PET) provides high quality tomographic images of the heart with accurate attenuation correction. The use of various compounds labeled with ultra-short lived positron-emitting radionuclides, such as 11C, 13N, 15O and 18F, allows physiological and biochemical measurements in vivo.

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 (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 Positron Emission Computed Tomography
2007Single photon emission computed tomography (SPECT) allows the user to obtain a threedimensional (3D) representation of the patient’s in vivo radiopharmaceutical distribution. Planar nuclear imaging leads to a twodimensional (2D) image of a 3D object.

Single Photon Emission Computer Tomography
2018In diesem Kapitel wird in den hauptsachlichen Aufbau und die wesentliche Funktionsweise konventioneller SPECT-Systeme eingefuhrt, wie sie in der standardmasigen nuklearmedizinischen Diagnostik Anwendung finden. Den zentralen Bestandteil eines konventionellen SPECT-Systems bilden i. Allg. mehrere Gammakameras, welche an einer rotierenden Aufnahmeeinheit

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 ...

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.
