Single photon emission computed tomography in Huntington's chorea

Psychiatry Research, 1989
Ten clinically affected patients (6 men, 4 women, aged 33-60 years) who met criteria for definitive HC (family history of at least one other member affected with typical symptoms of HC, dementia, impairment of voluntary movements, and chorea) and nine at-risk subjects (3 men, 6 women, aged 14-37 years) with a positive family history were ...

Single Photon Emission Computed Tomography in the Canine Lung

Journal of Computer Assisted Tomography, 1981
A whole body single photon emission computed tomographic system (SPECT) has been used to investigate canine pulmonary perfusion utilizing 99mTc-microspheres and has been compared to conventional radionuclide pulmonary perfusion studies. The SPECT data were reconstructed and displayed in 32 transverse, 16 sagittal, and 16 coronal plane sections ...

Thallium imaging with single photon emission computed tomography

American Heart Journal, 1987
Evaluation 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

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

Single Photon Emission Computed Tomography in Alzheimer's Disease

Archives of Neurology, 1989
To 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).

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 (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 and Renal Pseudotumor

Clinical Nuclear Medicine, 1985
Single photon emission computed tomography (SPECT), recently introduced into clinical nuclear medicine, potentially offers improved spatial resolution compared to planar imaging by eliminating activity from surrounding structures, and permitting three-dimensional reconstructions. Its clinical applications to date have been limited.

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 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.
