Brain SPECT Artifact in Multidetector SPECT System
Clinical Nuclear Medicine, 1994Stringent quality control cannot be overemphasized in performing SPECT. SPECT artifacts related to camera uniformity, center of rotation, and the patient's motion are well recognized. In this communication, another rare cause of a SPECT artifact related to a triad system is reported.

Preclinical SPECT and SPECT-CT in Oncology
2020Molecular imaging enables both spatial and temporal understanding of the complex biologic systems underlying carcinogenesis and malignant spread. Single-photon emission tomography (SPECT) is a versatile nuclear imaging-based technique with ideal properties to study these processes in vivo in small animal models, as well as to identify potential drug ...

Summary: The localizing value of ictal single‐photon emission computed tomography (SPECT) performed with cerebral blood flow agents in patients with epilepsy is based on cerebral metabolic and perfusion coupling. Ictal hyperperfusion is used to localize the epileptogenic zone noninvasively, and is particularly useful in magnetic resonance (MR ...

Seminars in Nuclear Medicine, 1999
Gated SPECT imaging has allowed the simultaneous assessment of both perfusion and function through one study. The popularity of this is amply shown by the unprecedented growth of this imaging modality throughout the country. In addition to the benefits that ventricular function adds to perfusion, gated SPECT imaging also adds to the specificity of ...

Clinical Nuclear Medicine, 1995
A 41-year-old woman had a mild confusional state after an assault. She reported a history of sexual promiscuity, and subsequent testing revealed a serum rapid plasma reagin titer of 1:64, a cerebral spinal fluid venereal disease research laboratory titer of 1:8, and fluorescent treponemal antibody absorption reactive in both serum and CSF ...

Conventional nuclear medical imaging uses radiopharmaceuticals labeled by single-photon emitters such as Tc-99m, I-123, or I-131 in vivo. Classical clinical examples are the study of bone metabolism by bone scintigraphy with the Tc-99m-labeled polyphosphonates or of iodine transport into the thyroid gland using Tc-99m-pertechnetate.

Neuroscience & Biobehavioral Reviews, 1994
SPECT studies for rCBF imaging in clinical epilepsy are reviewed divided into interictal, ictal and postictal SPECT studies in partial and generalized epilepsies, as compared with the corresponding PET studies, and at times referring to SPECT studies in experimental models of epilepsy.

Somatostatin is a peptide with a broad distribution in the nervous system and acts as a neurotransmitter in several organs, having a wide range of mainly inhibiting effects, such as the suppression of growth hormone release, as well as the inhibition of pancreatic and gastrointestinal hormone release.

Neurology, 1996
To the Editor: In their excellent paper, Dr. Gilman et al. [1] suggested that ``a study of patients with OPCA [olivopontocerebellar atrophy] using SPECT [single-photon emission computed tomography] to examine local cerebral blood flow (lCBF), and assessing the ability of SPECT measurements to differentiate between OPCA and normals might be useful ...
