The Attrius was developed to offer the nuclear cardiac PET imaging community the highest of quality imaging device at a most affordable price that when comparing the purchase, install and on-going maintenance competes directly with the lesser SPECT modality.


The small design footprint enables Attrius to be placed in most all hospitals, imaging facilities and offices. The Attrius PET is the only dedicated PET system in the world and most responsible choice when comparing to refurbished and used PET or PET-CT systems.



New advancements in PET imaging allow for the identification of coronary flow reserve, a measurement that detects the blood flow differences between rest and stress through the coronary arteries. This information, combined with the perfusion data, can help clinicians determine whether patients will benefit from mechanical revascularization.
