60 Years of Achievements by KSNM in Neuroimaging Research
Nucl Med Mol Imaging. 2022 Feb;56(1):3-16. doi: 10.1007/s13139-021-00727-1. Epub 2022 Jan 15.ABSTRACTNuclear medicine neuroimaging is able to show functional and molecular biologic abnormalities in various neuropsychiatric diseases. Therefore, it has played important roles in the clinical diagnosis and in research on the normal and pathological states of the brain. More than 400 outstanding studies have been conducted by Korean researchers over the past 60 years. In the 1990s, when multiheaded single-photon emission computed tomography (SPECT) scanners were first introduced in South Korea, stroke research using brain perfu...

IJERPH, Vol. 18, Pages 10633: Socio-Economic Disparities in Access to Diagnostic Neuroimaging Services in the United Kingdom: A Systematic Review
This study includes the analysis of diagnostic imaging used for dementia, minor head injury, stroke, cancer, epilepsy, chronic inflammatory demyelinating polyneuropathy and Parkinson’s disease. With this study, we aim to assess the health inequalities at disease diagnosis. Methods: Using Medline (via Ovid), PubMed and Web of Science databases as sources of information, we critically appraise existing studies on neuroimaging use in the U.K. health care system, published between January 2010 and February 2021. Findings: A total of 18 studies were included in this research, revealing that there was an increase in patients o...

Value of SPECT/CT over planar imaging during Tc-99m MDP triple phase bone scintigraphy for detection of osteomyelitis in patients with stage IV pressure ulcers
Conclusion: SPECT/CT imaging has a significant added diagnostic value over planar imaging in accurately detecting osseous involvement with stage IV pressure ulcers. It significantly reduced equivocal results by accurate uptake localization, reducing false positive results due to other associated pathologies and reducing false negative results due to overlap by other structures or difficult patient positioning.

Prognostic value of 99m Tc-ECD brain perfusion SPECT in patients with atrial fibrillation and dementia
ConclusionThis study demonstrated that decreased cerebral blood flow in the temporo-parieto-occipital lobe could be a potential prognostic value in patients with both AF and dementia.

Optimized sampling for high resolution multi-pinhole brain SPECT with stationary detectors.
Abstract Brain perfusion SPECT can be used in the diagnosis of various neurologic or psychiatric disorders, e.g. stroke, epilepsy, dementia and posttraumatic stress disorder. As traditional SPECT provides limited resolution and sensitivity, we recently proposed a high resolution focusing multi-pinhole clinical SPECT scanner dubbed G-SPECT-I (Beekman et al 2015). G-SPECT-I achieves data completeness in the scan region of interest by making small translations of the patient bed while using projections from all bed positions together for image reconstruction. A strategy to restrict the number of bed translations is d...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Brain imaging of locomotion in neurological conditions
Publication date: Available online 25 October 2018Source: Neurophysiologie CliniqueAuthor(s): Gilles Allali, Helena M. Blumen, Hervé Devanne, Elvira Pirondini, Arnaud Delval, Dimitri Van De VilleSummaryImpaired locomotion is a frequent and major source of disability in patients with neurological conditions. Different neuroimaging methods have been used to understand the brain substrates of locomotion in various neurological diseases (mainly in Parkinson's disease) during actual walking, and while resting (using mental imagery of gait, or brain-behavior correlation analyses). These studies, using structural (i.e., MRI) or ...

Rhenium and technetium complexes of thioamide derivatives of pyridylhydrazine that bind to amyloid- β plaques.
Rhenium and technetium complexes of thioamide derivatives of pyridylhydrazine that bind to amyloid-β plaques. J Biol Inorg Chem. 2018 Jul 07;: Authors: Fletcher SP, Noor A, Hickey JL, McLean CA, White JM, Donnelly PS Abstract Age-associated deposition of amyloid-β in cerebral blood vessels, a condition referred to as cerebral amyloid angiopathy, can contribute to stroke and dementia. This research aimed to design new radioactive technetium-99 m complexes that bind to amyloid-β plaques that have the potential to assist in diagnosis of cerebral amyloid angiopathy using single-photon-emitted computed...

Neurologic attack and dynamic perfusion abnormality in neuronal intranuclear inclusion disease
Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disease characterized by eosinophilic hyaline intranuclear inclusions in cells in the central, peripheral, and autonomic nervous system and visceral organs. Although clinical diagnosis was difficult until recently, an increasing number of adult cases of leukoencephalopathy have been diagnosed antemortem with NIID based on the characteristic hyperintensity in the corticomedullary junction on diffusion-weighted imaging (DWI) and confirmatory skin biopsy.1 While adult-onset NIID is characterized by slowly progressive dementia, it may also present with acute...

A review of the evidence of zolpidem efficacy in neurological disability after brain damage due to stroke, trauma and hypoxia: A justification of further clinical trials.
Authors: Sutton JA, Clauss RP Abstract During 15 years, 23 clinical reports and 6 studies have demonstrated associations between sub-sedative doses of zolpidem and recoveries from brain damage due to strokes, trauma and hypoxia. Clinical findings include unexpected awakenings from vegetative states and regressions of stroke symptoms after dosing that disappear during elimination and reappear on repeat dosing. Initially single-photon emission computed tomography scans showed improved perfusion within, around and distant from infarctions. Then positron emission tomography scans and electroencephalography detected ren...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

Regional Cerebral Blood Flow Single Photon Emission Computed Tomography for detection of Frontotemporal dementia in people with suspected dementia.
CONCLUSIONS: At present, we would not recommend the routine use of rCBF SPECT in clinical practice because there is insufficient evidence from the available literature to support this.Further research into the use of rCBF SPECT for differentiating FTD from other dementias is required. In particular, protocols should be standardised, study populations should be well described, the threshold for 'abnormal' scans predefined and clear details given on how scans are analysed. More prospective cohort studies that verify the presence or absence of FTD during a period of follow up should be undertaken. PMID: 26102272 [PubMed ...
