Validation of CBF measurement with non-invasive microsphere method (NIMS) compared with autoradiography method (ARG).
The purpose of this study is to examine the correlation of measured regional cerebral blood flow (rCBF) by means of a new microsphere method (non-invasive microsphere method), to the autoradiography (ARG) method, which is an established quantification method for 123I-IMP brain SPECT. The non-invasive microsphere (NIMS) method and ARG method were simultaneously applied to 30 patients, and quanti...
متن کاملQuantitative Measurement of Regional Cerebrovascular Reactivity to Acetazolamide Using 123I-N-Isopropyl-p-Iodoamphetamine Autoradiography with SPECT: Validation Study Using H2O with PET
A simplified technique using 123I-N-isopropyl-p-iodoamphetamine (123I-IMP) autoradiography (ARG) with SPECT has been proposed recently for quantifying regional cerebral blood flow (rCBF). To validate the accuracy of 123I-IMP-ARG for quantifying regional cerebrovascular reactivity (rCVR) to acetazolamide, we compared rCVR determined using 123I-IMP-ARG with that determined using H2O PET. Methods:...
متن کاملrCBF in neurodegenerative diseases as estimated by the autoradiographic (ARG) method and delayed I-123-IMP studies.
A total of 24 patients with a mean age of 45.8 +/- 20.8 were included in the study. The patients were grouped as Control (C), Degenerative Syndromes (DS), Degeneration Associated with External Factors (DEF), Degeneration Associated with Focal Neurologic Lesion (DFN) and Demyelinating Disease (DM). Imaging started 15 minutes for early and 4 hours for delayed scans after i.v. infusion of I-123 IM...
متن کاملA simple non-invasive I-123-IMP autoradiography method developed by modifying the simple non-invasive I-123-IMP microsphere method
Objective: We developed a simple non-invasive I-123-N-isopropyl-p-iodoamphetamine (123I-IMP) quantification method by analyzing chest RI-angiography and single photon emission computed tomography (SPECT) images based on the microsphere model (SIMS method). Theoretically, the SIMS method could be changed to the simple non-invasive ARG (SIARG) method by modifying the integrated washout ratio (WR)...
متن کاملPrediction of outcomes in MCI with 123I-IMP-CBF SPECT: a multicenter prospective cohort study
OBJECTIVE The multicenter prospective cohort study (Japan Cooperative SPECT Study on Assessment of Mild Impairment of Cognitive Function: J-COSMIC) aimed to examine the value of (123)I-N-isopropyl-4-iodoamphetamine cerebral blood flow (IMP-CBF) SPECT in regards to early diagnosis of Alzheimer's disease (AD) in patients with mild cognitive impairment (MCI). METHODS Three hundred and nineteen p...
