CardIQ Physio

A comprehensive view of myocardial perfusion and function.

Evaluation of myocardial tissue viability in patients with ischemic left ventricular dysfunction has important clinical and therapeutic implications. Since patients with ventricular dysfunction are at higher operative risk, cardiologists and cardiac surgeons often have to weigh the balance between the potential risks and benefit of revascularization procedures.

CardIQ Physio is a totally integrated post-processing assessment package that includes processing, visualization, and quantification protocols. CardIQ Physio gives you the ability to accurately and reproducibly quantify left ventricular volumes, ejection fractions, and myocardial mass. CardIQ Physio is optimized to perform cardiac function assessment using GE Discovery PET multi-bin and multi-slice cardiac PET images. This non-invasive method may aid in the diagnosis and treatment protocol of cardiovascular disease.

Intended Use
CardIQ Physio is an aiding tool for the clinicians to perform analysis of sets of stationary, dynamic, or gated PET trans-axial images via a number of display, measurement and batch filming/archive features. The measurements include perfusion, end-diastolic & end-systolic volumes, stroke volume, ejection fraction, myocardial mass, and transient ischemic dilatation. Also included is  a feature that enables clinicians to visualize reformatted PET perfusion and viability data, and make a comparison between the two. The perfusion or viability data can be acquired under stress or rest conditions and they can be processed individually or simultaneously.
