3D-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 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 ...
متن کاملAutomated quantification with BRASS reduces equivocal reporting of DaTSCAN (123I-FP-CIT) SPECT studies.
BACKGROUND ¹²³I-FP-CIT (DaTSCAN) SPECT studies of the nigrostriatal pathway are a valuable tool in the diagnosis of movement disorders. However some scans are reported as equivocal with potential adverse consequences. We investigated whether the use of quantification of tracer uptake within the striatum can be used to reduce the number of equivocal reports. MATERIAL AND METHODS BRASS software...
متن کامل[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 کاملValidation of Optimum ROI Size for 123I-FP-CIT SPECT Imaging Using a 3D Mathematical Cylinder Phantom
Objective(s): The partial volume effect (PVE) of single-photon emission computed tomography (SPECT) on corpus striatum imaging is caused by the underestimation of specific binding ratio (SBR). A large ROI (region of interest) set using the Southampton method is independent of PVE for SBR. The present study aimed to determine the optimal ROI size with contrast and SBR for striatum images and val...
