[123I]FP-CIT SPECT in atypical degenerative parkinsonism
Parkinson’s disease (PD) is the second most common neurodegenerative disorder [1], yet early accurate diagnosis remains challenging. The estimated prevalence of PD is 0.5–1% in those aged 65–69 years and 1–3% in those aged ≥80 years [1]. Although the clinical diagnosis of PD may be straightforward in cases with a classic presentation [2], accurate distinction between PD and atypical degenerativ...
متن کامل3D-OSEM and FP-CIT SPECT quantification: benefit for studies with a high radius of rotation?
OBJECTIVES Dopamine transporter imaging with single-photon emission computed tomography (SPECT) is a valuable tool for both clinical routine and research studies. Recently, it was found that the image quality could be improved by introduction of the three-dimensional ordered subset expectation maximization (3D-OSEM) reconstruction algorithm, which provides resolution recovery. The aim of this s...
متن کاملFocal 123I-FP-CIT SPECT Abnormality in Midbrain Vascular Parkinsonism
Cerebrovascular diseases are considered among possible causes of acute/subacute parkinsonism, representing up to 22% of secondary movement disorders. In cases of suspected vascular parkinsonism (VP), dopamine transporter SPECT has been highly recommended to exclude nigrostriatal dopaminergic degeneration. We report the case of a hemiparkinsonism related to a left midbrain infarct with focal lat...
متن کاملImaging of serotonin transporters with [123I]FP-CIT SPECT in the human hypothalamus
BACKGROUND Serotonergic neurons in the rodent hypothalamus are implicated in key neuroendocrine and metabolic functions, including circadian rhythmicity. However, the assessment of the serotonergic system in the human hypothalamus in vivo is difficult as delineation of the hypothalamus is cumbersome with conventional region-of-interest analysis. In the present study, we aimed to develop a metho...
متن کاملI]FP-CIT SPECT images
Aim The purpose of the current paper is to present a computational solution to accurately quantify a specific to a non-specific uptake ratio in [ 123 I]FP-CIT single photon emission computed tomography (SPECT) images and simultaneously measure the spatial dimensions of the basal ganglia, commonly known as basal nuclei. A statistical analysis based on a reference dataset selected by the user is ...
