SPECT: SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY

Journal of Computer Assisted Tomography, 1980
Interest in single photon emission computed tomography (SPECT) has been renewed as a result of the successful application of transmission (x-ray) CT to diagnostic radiology. Many aspects of SPECT are different from those encountered in transmission CT, and often are more difficult to overcome.

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

Single-Photon Emission Computed Tomography/Computed Tomography in Abdominal Diseases

Seminars in Nuclear Medicine, 2007
Single-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.

[Positron emission computed tomography].

Journal of cardiology. Supplement, 1989
Positron 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/Computed Tomography in Brain Tumors

Seminars in Nuclear Medicine, 2007
Anatomic imaging procedures (computed tomography [CT] and magnetic resonance imaging [MRI]) have become essential tools for brain tumor assessment. Functional images (positron emission tomography [PET] and single-photon emission computed tomography [SPECT]) can provide additional information useful during the diagnostic workup to determine the degree ...

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).

The Diagnosis of Dementia With Single Photon Emission Computed Tomography

Archives of Neurology, 1987
Single 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

Recent Developments in Instrumentation for Emission Computed Tomography

Seminars in Nuclear Medicine, 1980
Equipment for emission tomography is currently undergoing a rapidly changing stage of development, both for single-gamma detection and for tomography using positron emitters. For single-gamma longitudinal tomography, the 7-pinhole collimator has won wide acceptance because of it simplicity and rapid reconstruction times.

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.
