Review examines partial volume correction methods in emission tomography, highlighting how anatomical data improves quantification across neurology, cardiology, and oncology.

Key Points

Summarize the physical mechanisms underlying partial volume effects in emission tomography and evaluate algorithmic correction strategies across major clinical imaging specialties.
Assessed theoretical limitations of spatial resolution and point spread functions in PET and SPECT imaging systems.
Reviewed mathematical approaches to partial volume correction, including unconstrained inverse filtering and anatomical regularization via co-registered CT or MRI.
Surveyed practical implementations and case examples within clinical neurology, cardiology, and oncology.
Inverse filtering methods reliably reverse resolution degradation in theory but trigger substantial noise amplification and image artefacts without regularization.
Integrating anatomical boundary data from co-registered CT or MRI provides effective regularization, suppressing noise while preserving structural fidelity.
Implementation of partial volume correction substantially improves quantitative accuracy in clinical assessments of brain metabolism, myocardial perfusion, and tumor uptake.
