GE Healthcare CardIQ Physio Brochure

A comprehensive view of myocardial
perfusion and function.

GE Healthcare

Overview

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.
Optimized to perform cardiac function
assessment using GE Discovery PET
multi-bin, multi-slice cardiac PET
images, this non-invasive method may
aid in the diagnosis and treatment
protocol of cardiovascular disease.

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.

 Smart smoothing improves IQ

of functional maps in presence
of noise.

 Streamlined workflow for tissue

classification.

 Permits injection rates of

4cc/sec.

 Features CT brain stroke and

tumor protocols.

 Offers a variety of functional

maps.

Features

• Review features include:

- Load up to three static, gated, or

dynamic series.

- Polar maps to help you visualize

disease or defect.

- Polar maps in ASNC layouts with

vasculature territorial overlays.

- Automated re-orientation

- Flexible or customizable 3D

volume filtering.

- Flexible summing of gated and

dynamic studies.

• Perfusion analysis includes:

- Estimated mass, rest/stress/

reversibility severity scores.

- Extent of perfusion defect.

• Viability assessment includes:

- Extent of viability of an area.

- FDG/perfusion match/mismatch

tool for viability assessment
using metabolic studies.

• Functional analysis includes:

- Left ventricle volume plot

- End of diastole volume

- End of systole volume

- Stroke volume

- Ejection fraction

- Mass

- Index of possible TID

• Left ventricular wall assessment via

cine captures motion of
myocardium along epicardial and
endocardial contours.

• Dynamic analysis allows you to

select a subset of short axis images
in DICOM for mat for 3rd party
software myocardial blood flow
analysis.

Indications for 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 could have
been acquired under stress or rest
conditions and they can be
processed individually or
simultaneously.

- LV ejection fraction.

- Oblique slice images.

- Any screen and viewport.

System Requirements

CardIQ Physio is available as a full
package on AW 4.2p or higher, and
includes PET functionalities.

To take full advantage of CardIQ
Physio functionalities, cardiac images
must be acquired on a GE PET/CT
system equipped with the following
functionalities:

• CT Operator Console Software for

Prospective Gating and CardIQ
Snapshot for Retrospective Gating
and Reconstruction for Helical CTA
studies

• Gating Interface Kit for Discovery

ST, LS, or DSTE.

• Ivy 3100 or 3150 EKG Monitor.

• EKG Simulator and Adaptor (not

needed with 3150)
