Methods Patients with a history of positive antiphospholipid antibodies and neuropsychiatric symptoms but without thromboembolism composed the case group; patients without antiphospholipid antibody served as the control group. Subjects with autoantibodies to extractable nuclear antigens were excluded from this study. All patients underwent Tc-99m ECD SPECT and were classified by the number of positive antiphospholipid antibodies they carried. The heterogeneity of brain perfusion was defined as the coefficient of variation. Analysis of variance (ANOVA) was used to evaluate the differences between groups. ...http://lupus.bmj.com/content/4/Suppl_1/A8.3

Cognitive-nigrostriatal relationships in de novo, drug-naïve Parkinson's disease patients: a [I-123]FP-CIT SPECT study. -...
To unveil cognitive-nigrostriatal correlations in Parkinson's disease (PD), 30 de novo, drug-naïve PD patients and 15 patients with essential tremor (Controls, CTR) underwent a neuropsychological (NPS) battery and brain SPECT with [I-123]Ioflupane, as a biomarker of nigrostriatal function. Automatic extraction of uptake at caudate and putamen level was conducted through the BasGan software, also allowing partial volume effect correction. Because of the multicollinearity among neuropsychological tests and among SPECT variables, factor analysis was applied to 16 neuropsychological scores; moreover, the four SPECT variables were merged into a mean SPECT value (mSPECT). Factor analysis identified four NPS factors: a dys-executive (NPS-EX), a visuospatial (NPS-VS), a verbal memory (NPS-VM), and a 'mixed' (NPD-MIX) factor. In PD group, there were inverse correlations between UPDRS-III score and both NPS-VS (P | 0.01) and mSPECT (P | 0.05), and a direct correlation between mSPECT and NPS-EX (P | 0.05).

OSA | Method for reducing background artifacts from images in single-photon emission computed tomography with a uniformly...
Uniformly redundant array coded apertures have proven to be useful in the design of collimators for x-ray astronomy. They were initially expected to be equally successful in single-photon emission computed tomography (SPECT). Unfortunately, the SPECT images produced by this collimator contain artifacts, which mask the true picture and can lead to false diagnosis. Monte Carlo simulation has shown that the formation of a composite image will significantly reduce these artifacts. A simulation of a tumor in a compressed breast phantom has produced a composite image, which clearly indicates the presence of a 5 mm × 5 mm × 5 mm tumor with a 6:1 intensity ratio relative to the background tissue.. © 2002 Optical Society of America.

A star whose spectrum reveals the presence of the element technetium. The first such stars were discovered in 1952 and provided the first direct evidence for stellar nucleosynthesis - the manufacture of heavier elements from lighter ones in stellar interiors. Because the most stable isotopes of technetium have half-lives of only a few million years, the only way this element could be present inside stars is if it had made there in the relatively recent past. Technetium is observed in some M stars, MS stars, MC stars, S stars, and C stars ...http://www.daviddarling.info/encyclopedia/T/technetium_star.html
Follow-up study of depression in the elderly. Clinical and SPECT data. - Department of Psychiatry
BACKGROUND: Imaging studies in depression of the elderly are often small and highly selective. AIMS: To investigate a large group of elderly depressed patients in order to assess changes in clinical, imaging and neuropsychological variables at follow-up. METHOD: Patients (n = 175, age range 65-91 years) with clinical depression were identified from consecutive local referrals. Clinical interviews, neuropsychological tests and SPECT scans were carried out at referral and at two-year follow-up. RESULTS: Of 84 re-examined patients, 46.5% were well, 9.5% were ill, 33% partially recovered and 11% had developed dementia. Duration of illness before index assessment was the only factor to predict outcome. Thirty-nine patients could be scanned and followed up. There were no differences between patients with good or poor depressive outcome on SPECT. Ten clinically improved patients could be re-examined with SPECT. There were relative increases in right cingulate gyrus and right cerebellum at follow-up.https://www.psych.ox.ac.uk/publications/583014
A Study of 123I-CMICE-013 Radiopharmaceutical in Healthy Volunteers - Full Text View - ClinicalTrials.gov
Single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is an established, cost effective tool for the risk stratification and management of patients suspected or known to have coronary artery disease (CAD)Myocardial perfusion imaging is significantly affected by interruptions in the supply of 99mMo, the parent isotope of 99mTc used for the majority of MPI. An alternative radiotracer, I123-CMICE-013,developed at the Canadian Molecular Imaging Center of Excellence (C-MICE) at the University of Ottawa Heart Institute, has completed pre-clinical trial testing and is ready for Phase 1 human trials.. This Phase I study will be a single centre, open label study. Subjects will receive 2 doses of study drug. One rest dose and one stress dose will be administered on separate days, one week apart. Subjects will undergo a standard clinical exercise stress protocol for the stress dose. Gamma camera imaging following each administration will be done over 2 ...https://clinicaltrials.gov/ct2/show/NCT01558362

PBMC (Peripheral Blood Mononuclear Cells) /Lymphocyte SPECT (Single Photon Emission Computerized Tomography) Imaging in Crohn...
This study is based on the established technology of scintigraphic 'white cell scanning', in which the leukocytes in a limited volume of patient's blood are radiolabeled with indium-111 or technetium-99m, re-introduced into the circulation, and their subsequent trafficking and accumulation in areas of active inflammation is visualised by scintigraphic imaging. This methodology is routinely used for diagnosis of inflammatory conditions and pharmacodynamic changes have been documented in the literature. As it is intended that this technology could be used in future drug intervention studies.. However, because this sub-population labelling methodology remains exploratory, this study will investigate the utility of such techniques for use in future clinical trials in Crohn's patients.. Two parallel exploratory approaches will be investigated to enrich for lymphocyte populations expressing leukocyte trafficking inhibitors. In the first, whole blood will be fractionated on a ficoll gradient to purify ...https://clinicaltrials.gov/ct2/show/NCT01051622
Specialty Clinical - AAMS
Pre-hospital and critical care transport medicine are rapidly advancing fields with implementation of new technology and research based care. In effort to improve patient outcomes, we continually look for diagnostic measures to confirm clinical impressions. Ultrasound (US) technology is becoming more readily available outside of the hospital and can be used to guide definitive interventions. This presentation discusses the benefits of ultrasound use in the settings of ACS (Acute Coronary Syndromes) and even Cardiac Arrest. US imagery is used to show valve dysfunction, areas of compromised cardiac muscle as well as pericardial effusion/tamponade. Materials covered are basics of image interpretation, optimal probe placement and actual case presentations. These cases demonstrate ways in which US was used to confirm extent of myocardial injury in ACS/STEMI and even myocardial activity in the presence of apparent cardiac arrest. The most interesting case and inspiration for this presentation was a ...http://aams.org/education-meetings/specialty-clinical-sessions/
