Usually, the gamma-emitting tracer used in functional brain imaging is 99mTc-HMPAO (hexamethylpropylene amine oxime). 99mTc is a metastable nuclear isomer that emits gamma rays that can be detected by a gamma camera. Attaching it to HMPAO allows 99mTc to be taken up by brain tissue in a manner proportional to brain blood flow, in turn allowing cerebral blood flow to be assessed with the nuclear gamma camera. Because blood flow in the brain is tightly coupled to local brain metabolism and energy use, the 99mTc-HMPAO tracer (as well as the similar 99mTc-EC tracer) is used to assess brain metabolism regionally, in an attempt to diagnose and differentiate the different causal pathologies of dementia. Meta-analysis of many reported studies suggests that SPECT with this tracer is about 74% sensitive at diagnosing Alzheimers disease vs. 81% sensitivity for clinical exam (cognitive testing, etc.). More recent studies have shown the accuracy of SPECT in Alzheimers diagnosis may be as high as 88%.[4] In ...
First they compared healthy controls with depressed patients without medication for at least 2 weeks before undergoing SPECT. Single photon emission computed tomography (SPECT) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera. However, it is able to provide true 3D information. Usually the gamma-emitting tracer used in functional brain imaging is 99mTc-HMPAO (hexamethylpropylene amine oxime). 99mTc is a metastable nuclear isomer which emits gamma rays which can be detected by a gamma camera. When it is attached to HMPAO, this allows 99mTc to be taken up by brain tissue in a manner proportial to brain blood flow, in turn allowing brain blood flow to be assessed with the nuclear gamma camera. Because blood flow in the brain is tightly coupled to local brain metabolism and energy use, the 99mTc-HMPAO tracer (as well as the similar 99mTc-EC tracer) is used to assess brain metabolism regionally ...
We used 99mTc-hexamethylpropyleneamine oxime single-photon emission computed tomography (SPECT) to study cerebral perfusion in patients treated with streptokinase for acute ischemic stroke in an open and prospective study. Our primary aims were (1) to compare the extent of reperfusion between patients who had received thrombolytic therapy and a control group studied during the same period who were ineligible to receive such therapy and (2) to determine if, among all patients, reperfusion led to improved outcome.. Fifty-seven patients (22 treated with streptokinase) had two SPECT studies performed, the first before streptokinase administration and the second 24 hours later.. On the first SPECT study hyperfusion was present in the middle cerebral artery or anterior cerebral artery territories in 40 patients (17 treated with streptokinase). Patients in the treatment and control groups with initial hypoperfusion on SPECT were well matched for the volume of the perfusion defect and the severity of ...
This is the first study to have determined the extent to which99mTc-HMPAO SPECT contributes to the clinical differentiation of dementing conditions. Moreover, it has provided information that is useful to the clinician in the interpretation of individual test results and a guide to the optimal clinical usage of CBF imaging in the diagnosis of dementia.. To facilitate the interpretation of individual patterns of CBF abnormality, it is suggested that table 3 is used as follows: if a demented patient is considered to have either Alzheimers disease or vascular dementia at initial presentation (table 3a) on the basis of neuropsychological evaluation, neurological examination, and CT, then bilateral posterior CBF abnormality or bilateral posterior plus unilateral anterior CBF abnormality provides support for the diagnosis of Alzheimers disease. By contrast, bilateral anterior CBF abnormality, bilateral anterior plus unilateral posterior CBF abnormality, or "patchy" CBF changes provide support for ...

Brain perfusion SPECT is highly useful for the diagnosis of the dementias, including Alzheimers disease, Fronto-Temporal Dementia, and Lewy Body Disease. Studies of the accuracy of SPECT for diagnosing Alzheimers Disease report sensitivities of 65%-85% and specificities (for other dementias) of 72%-87% (1) In the largest study to date, both HMPAO SPECT and 18F-FDG PETwere able to completely separate 26 AD cases from controls (2) SPECT has been advocated over18F-FDG PET on the basis of its wider availability, lower cost, and perceived better patient tolerability, although a recent review suggested 18F-FDG PET had greater diagnostic accuracy over Brain Perfusion SPECT where available (3) Guidelines of the European Association of Nuclear Medicine and the American College of Radiology endorse the clinical use of Brain Perfusion SPECT in the workup and diagnosis of dementia (4,5).. Brain perfusion SPECT is useful because the clinical diagnosis of dementia is often inaccurate, especially in early ...

RATIONALE AND OBJECTIVES: In the general context of perfusion pattern modeling from single-photon emission computed tomographic (SPECT) data, the purpose of this study is to characterize interindividual functional variability and functional connectivity between anatomic structures in a set of SPECT data acquired from a homogeneous population of subjects. MATERIALS AND METHODS: From volume of interest (VOI)-perfusion measurements performed on anatomically standardized SPECT data, we proposed to use correspondence analysis (CA) and hierarchical clustering (HC) to explore the structure of statistical dependencies among these measurements. The method was applied to study the perfusion pattern in two populations of subjects; namely, SPECT data from 27 healthy subjects and ictal SPECT data from 10 patients with mesio-temporal lobe epilepsy (MTLE). RESULTS: For healthy subjects, anatomic structures showing statistically dependent perfusion patterns were classified into four groups; namely, temporomesial
The introduction of acetylcholinesterase inhibitor therapy for AD has demonstrated for the first time that the progression of this fatal disease can be affected, albeit temporarily.11 As treatments become more powerful and effective it will become increasingly important to make an early and accurate diagnosis in the earliest stages of cognitive impairment.. Several groups have reported posterior cortical atrophy-either bi-parietal and/or occipito-temporal involvement-as a presentation in AD. An informative study noted that patients with the bi-parietal variant present with visuo-spatial problems-that is, agraphia and dyspraxia- which may progress to Balints syndrome (visual disorientation, optic apraxia, and simultanagnosia) whereas patients with the occipito-temporal variant, the visual variant of AD, present with complaints of visual distortion, difficulty with object recognition, topographical agnosia, and alexia.12 Histopathological material is becoming available in an accruing number of ...
A very simple and low-cost brain dedicated, rapidly rotating Single Photon Emission Tomograph SPECT is described. Its use in following patients with ischemic stroke is illustrated by two middle cerebral artery occlusion cases, one with persistent occlusion and low CBF in MCA territory, and one with early lysis of the occlusion having high CBF (massive luxury perfusion) for some weeks. Evidence of this kind may be essential in the evaluation of therapeutic measures in ischemic stroke. ...
For thousands of years, we, as humans, have sought to understand the mechanisms responsible for neural activity (Walsh, 1978). As long ago as 10,000 B.C., craniotomies are known to have been performed. In the 1500s, Vesalius published the first anatomic drawings of the brain after an unprecedented observation and dissection of the brain. In the 19th century, lesion studies introduced the lesion/deficit hypothesis of neural functioning, which subsequently led to much of the current functional neuroanatomical terminology (e.g., Brocas and Wernickes areas). Through the last few decades of what may be considered modern neural research, a "greater interest in the cognitive correlates of structural and functional brain lesions" has led to the development of todays technology for imaging the nervous system (Mega, 1999, p. 41 ...

We evaluated the feasibility of interictal single photon emission computed tomography (SPECT) to detect alterations in regional cerebral blood flow and neuronal activity in dogs with idiopathic epilepsy. Twelve dogs with idiopathic epilepsy underwent interictal technetium-99m-ethyl cysteinate dimer SPECT of the brain. Different cortical regions of interest (ROIs), 1 ROI at the cerebellum and 1 ROI at the subcortical area were evaluated by semiquantitative analysis and compared with a control group (18 dogs). Significant hypoperfusion (P=0.02) was present in the subcortical area of epileptic dogs. This hypoperfusion was not associated with seizure frequency, age at onset of seizures, duration of epilepsy, or time since the last seizure. Interictal SPECT did not reveal cortical or cerebellar perfusion alterations. The subcortical area may play an important role in the pathophysiology of canine idiopathic epilepsy. ...
Background: For a quantitative comparison of images obtained during 99mTc-hexamethylpropylene amine oxime (HMPAO) single-photon emission computed tomography (SPECT), brain activity values are usually normalized to a reference region. In studies of Alzheimer-type dementia (ATD), the cerebellum is often used as a reference region, assuming that it is spared any major pathological involvement. Statistical parametric mapping (SPM) may enhance the evaluation of SPECT scans in ATD patients. However, current SPM software only allows scaling to average whole brain activity (i.e., global normalization). The aim of this study was to develop an easily applied, objective, and reproducible method for determining average cerebellar tracer uptake so that images can be scaled specifically to cerebellar activity prior to the performance of SPM analysis. We also investigated whether cerebellar normalization increases the sensitivity and specificity of SPM analysis of ATD patients compared with global ...

PURPOSE To characterize perfusion patterns of periictal single-photon emission tomography (SPECT) in patients with unilateral temporal lobe epilepsy (TLE) and to determine their relationship to the epileptogenic zone (EZ). METHODS We studied periictal SPECT scans of 53 patients after anterior mesial temporal lobectomy who had good seizure outcome after surgery. Ictal SPECT scans were performed during video-EEG monitoring. Typical SPECT patterns consisted of ipsilateral ictal hyperperfusion or ipsilateral postictal hypoperfusion. Atypical ictal patterns included normal scans, bilateral temporal hyperperfusion, or contralateral patterns. These perfusion patterns were retrospectively analyzed searching for concordance rate with the EZ. RESULTS We obtained 51 ictal and two early postictal scans. In the typical group, 40 (75.4%) patients had ipsilateral ictal temporal lobe hyperperfusion, and one (1.9%) patient had ipsilateral postictal temporal lobe hypoperfusion. Twelve (22.7%) patients exhibited

article{412594, abstract = {Impulsive aggression in dogs has an important impact on human public health. Better insight into the pathophysiology of this phenomenon could lead to more adequate diagnosis and treatment. Indirect in vivo research on peripheral body fluids and post-mortem studies in impulsive animals and humans indicate a deficient serotonergic system in general and disturbances in the serotonin-2A (5-HT2A) receptor in particular. In this study, brain perfusion and the 5-HT2A receptors were examined in impulsive, aggressive dogs, in comparison with a group of normally behaving animals. In order to decide which dogs to include in this study, owners were asked to describe the general behaviour of the dogs, the circumstances in which aggression occurred and their conduct during aggressive acts. Finally, 19 dogs were retained for this study, showing, according to different behavioural specialists, disinhibited dominance aggression. Functional imaging studies were performed on all these ...

Investment Costs for the Separation Nozzle Process Investment Costs for the Gaseous Diffusion Process. Thus, in spite of the fact that, according to the estimate above, the specific suction volume is greater by a factor of 8.8 one would not expect an appreciably greater investment cost for the separation nozzle process than for the gaseous diffusion process. It is expected that the separation nozzle process will have a real advantage compared to the gaseous diffusion process with respect to the equilibrium time of a separation cascade. By the term, equilibrium time, one refers to the time required between the start-up of a cascade and the attainment of the product concentration, i.e. the time during which no product can be withdrawn. The equilibrium time for cascades which enrich 235U to medium or high concentrations can be so long that they may not be neglected in the economic considerations. Foragiven separation job, the equilibrium time is directly proportional to the average residence time ...

A patient who suffered a transient global amnesia (TGA) attack underwent regional cerebral blood flow (rCBF) SPECT imaging and neuropsychological testing in the acute phase, after one month and after one year. Neuropsychological testing in the acute phase showed a pattern of anterograde and retrograde amnesia, whereas memory was within age normal limits at follow up. SPECT data were analysed with a within subject comparison and also compared with those of a group of healthy controls. Within subject comparison between the one month follow up and the acute phase detected increases in rCBF in the hippocampus bilaterally; further rCBF increases in the right hippocampus were detected after one year. Compared to controls, significant hypoperfusion was found in the right precentral, cingulate and medial frontal gyri in the acute phase; after one month significant hypoperfusion was detected in the right precentral and cingulate gyri and the left postcentral gyrus; after one year no significant hypoperfusion
