Single-photon emission-computed tomography (SPECT)

1998
Abstract 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, 1996
Neuroimaging 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

Single-Photon Emission Computed Tomography (SPECT)

2003
Single-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

2006
Conventional 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 in epilepsy

Seminars in Nuclear Medicine, 1990
Functional brain imaging by either single photon emission computed tomography (SPECT) or positron emission tomography (PET) is now a well-established technique in the diagnosis and evaluation of the epilepsies. Perhaps only in stroke have these emerging technologies proven of greater significance. Scalp, cortical, or depth electroencephalographic (EEG)

Brain single‐photon emission computed tomography ^*

Neurology, 1994
Single-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 ...

Quantitative single-photon emission computed tomography imaging

Current Cardiology Reports, 2005
Over the past decade, quantitation of cardiac single-photon emission computed tomography (SPECT) data, once limited to perfusion assessment, has been extended to global and regional function assessment for both the left and the right ventricle, as well as to measurement of additional cardiac parameters of diagnostic and prognostic interest. A number of

Single Photon Emission Computed Tomography Brain Imaging

Neurosurgery Clinics of North America, 1996
SPECT brain perfusion imaging has definite value in the evaluation of cerebrovascular disease (particularly acute stroke), dementia, epilepsy, and may have a role in the diagnosis of brain death and head trauma. SPECT with tumor tracers T1-201 and Tc-99m sestamibi shows promise for detecting tumor recurrence.

Single Photon Emission Computer Tomography

2018
In 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
