Although this method reduces the harmful influence of the partial-volume effect and inter-operator variability, it has some disadvantages. This method defines the SBR index as the count concentration of the striatal VOI (reflecting specific binding) divided by the count concentration of the whole brain except for the striatum (reflecting non-specific binding). Specifically, the method applies a large pentagonal prism-shaped VOI setting that encompasses a wide area around the striatum, thereby reducing the partial-volume effect. developed the Southampton method, a semi-quantitative method based on the volume of interest (VOI), that has gained widespread use. Quantitative assessments, such as the specific binding ratio (SBR), are particularly effective in cases with subtle reductions in striatal tracer uptake, which are difficult to register with visual interpretation alone. Quantitative assessments are therefore used in addition to visual interpretation when performing DAT SPECT, and previous reports have indicated that a combination of visual interpretation and quantitative assessment achieves more accurate diagnoses. However, a previous study indicated that a suboptimal inter-observer agreement may lead to variable interpretation of DAT SPECT images, indicating that the efficacy of DAT SPECT may rely on visual interpretation. 0.917, p < 0.005).ĭopamine transporter (DAT) single-photon emission computed tomography (SPECT) is an imaging modality that can effectively differentiate neurodegenerative parkinsonian syndromes (PS), including Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) from other neurological disorders not characterized by dopaminergic degeneration, such as Alzheimer disease, drug-induced Parkinsonism, and essential tremor.
When corrected for attenuation, significant differences in the AUC were observed in all three EI groups (low EI group, AUC = 0.961 vs. 0.942, p = 0.11) in the middle and high EI groups, the CSF-mask algorithm performed better than the non-CSF-mask algorithm (middle EI group, AUC = 0.894 vs. When not corrected for attenuation, no significant difference in the AUC was observed in the low EI group between the non-CSF-mask and CSF-mask algorithms (0.927 vs. If all else fails, they provide the user with a support portal and email to get in touch with their team to help serve their customer better.ROC analyses demonstrated that the CSF-mask algorithm performed better than the non-CSF-mask (no correction, area under the curve = 0.917 vs. This includes answers to features or just general assistance.
