DOI: 10.1002/mp.15707
Abstract: PURPOSE Dual respiratory-cardiac gating reduces respiratory and cardiac motion blur in myocardial perfusion (MP) SPECT. However, image noise is increased as detected counts are reduced in each dual gate (DG). We aim to develop a… read more here.

DOI: 10.1007/s11604-024-01612-5
Abstract: The findings of brain perfusion single-photon emission computed tomography (SPECT), which detects abnormalities often before changes manifest in morphological imaging, mainly reflect neurodegeneration and contribute to dementia evaluation. A major shift is about to occur… read more here.

DOI: 10.1111/cpf.12899
Abstract: Myocardial perfusion SPECT (MPS) and exercise electrocardiography (Ex‐ECG) results are of prognostic importance for short‐term follow up duration. However, the value of MPS or Ex‐ECG findings for long‐term risk assessment is less evident as underlying… read more here.
