18-FDG Single Photon Emission Computed Tomography in Heart and Brain Scintigraphy: Instrumentation and Physical Aspects

  • Chapter
Radioactive Isotopes in Clinical Medicine and Research

Part of the book series: Advances in Pharmacological Sciences ((APS))

Summary

The physical properties of a conventional dual-head gamma camera system with particularly designed extra-high-energy collimators for the purpose of detecting radiation from positron emitters were investigated. The system sensitivity for F-18 was found to be 50.3 cpm /37 kBq, which is 25% of the sensitivity for Tc-99m with a high-resolution collimator. The FWHM of the line spread function for a source-collimator distance of 10 cm was measured to 12.0 mm in air. Reconstructed images of a SPECT phantom showed the necessity for a Compton correction in double-isotope studies with both F-18 and Tc-99m, which is performed by counting photons in a third energy window at 170 keV.
