Study finds PET no better than SPECT

Positron emission tomography (PET) is no better than single-photon emission computed tomography (SPECT) in the evaluation of ischemic heart disease, according to a technology assessment published by ECRI.
The study, sponsored by the Plymouth Meeting, PA-based nonprofit group, concluded that PET images provide better contrast and spatial resolution than SPECT in assessments of myocardial blood flow and viability. The group found that the difference had little effect on clinicians' ability to diagnose coronary artery disease, however.
The study concluded that there is some question as to when PET's expense and clinical value justify its use over SPECT. The study was prepared by ECRI's Health Technology Assessment Information Service.
Assessing MACE Risk in Women: Can an Emerging Model with SPECT MPI Imaging Have an Impact?
December 9th 2024In research involving over 2,200 women who had SPECT MPI exams, researchers found that those who had a high score with the COronary Risk Score in WOmen (CORSWO) model had a greater than fourfold higher risk of major adverse coronary events (MACE).
