Anatomically CT-guided iterative reconstruction using KEM for sparse projection 99mTc-MDP Bone SPECT/CT: quantitative validation in metabolic imaging
The KEM algorithm significantly enhanced lesion conspicuity (superior T/Bmax, T/Bmean) while maintaining OSEM-equivalent accuracy under low projections. This suggests potential for optimizing SPECT/CT workflow by reducing acquisition time without compromising diagnostic quality.
