[ 1 ] - A 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)...

[ 2 ] - Usefulness of an Automatic Quantitative Method for Measuring Regional Cerebral Blood Flow Using 99mTc Ethyl Cysteinate Dimer Brain Uptake Ratio

 Objective(s): Improved brain uptake ratio (IBUR), employing 99mTc-ethyl cysteinate dimer (99mTc-ECD), is an automatic non-invasive method for quantitatively measuring regional cerebral blood flow (rCBF). This method was developed by the reconstruction of the theory and linear regression equation, based on rCBF measurement by H215O positron emission tomography. Clarification of differences in r...
