Final Summary Report of Nordic Nuclear Safety Research, NKS

Diagnostic accuracy in identifying cardiac coronary artery disease for PET and SPECT is 95% and 83% respectively. This represents the major advantage of SPECT as a molecular imaging technique, since it is significantly cheaper than either PET or fMRI. However it lacks good spatial (i.e., where exactly the particle is) or temporal (i.e., did the contrast agent signal happen at this millisecond, or that millisecond) resolution. 2014-11-11 · SPECT and 18F-FDG PET differ in the equipment needed, im-age characteristics, availability, and patient experience.
