Single-Photon Emission Computed Tomography/Computed Tomography in Abdominal Diseases
Seminars in Nuclear Medicine, 2007Single-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.

Single-Photon Emission Computed Tomography/Computed Tomography in Brain Tumors
Seminars in Nuclear Medicine, 2007Anatomic 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 (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 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

Quantitation in Positron Emission Computed Tomography
Journal of Computer Assisted Tomography, 1980Effect of insufficient transverse sampling on quantitative positron emission computed tomography (ECT) was investigated with computer simulation and measurements on parallel bar and line source phantoms. Aliasing artifacts were observed and were found to be dependent on both the configuration and the location of imaged objects.

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.

Recent Developments in Instrumentation for Emission Computed Tomography
Seminars in Nuclear Medicine, 1980Equipment 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.
