Methods for Quantitative SPECT Imaging Physics Applied Math Estimation Theory Well characterized Accuracy: <5% for organs <10% at system resolution Precision: on order of accuracy Quantitative SPECT • Single Radionuclide: • Tc-99m, Tl-201, In-111, I-131, I-123, … • Simultaneous Dual Radionuclide: • Tc-99m/Tl-201 • Tc-99m/In-111 • Tc-99m/I-123 • In-111/I-131 • Compensation for: • Attenuation • Scatter • Spatially varying resolution • Partial volume effects I-123 Brain Phantom
Clinical Applications of Quantitative SPECT • Targeted radiotherapy dosimetry • Quantitative tumor response (e.g., In-111 Octreoscan, I-123 MIBG) • Simultaneous rest/stress myocardial perfusion imaging • Simultaneous myocardial perfusion/innervation imaging
