| Inter-institutional reproducibility Quantitative agreement of CBF/CVR measurements was investigated using 123I-iodoamphetamine SPECT and the DTARG method. Subjects with cerebrovascular disease were investigated first on a Toshiba 9300A SPECT system with an N1 collimator (institution O), thereafter on a Siemens ECAM with LMEGP collimator (institution Y). Data were quantitatively reconstructed. Rest and stress CBF, CVR and disease stage showed high agreement5). 5) Yonada H, et al: Reproducibility of cerebral blood flow assessment using a quantitative SPECT reconstruction program and split-dose 123I-iodoamphetamine ininstitutions with different c-cameras and collimators Journal of Cerebral Blood Flow & Metabolism 2012, 1–8 |
