Image-guided therapy
iFR
Be confident in treatment and deferral decisions with Philips iFR
iFR is in a class of its own and is the leading hyperemia-free physiologic index for measuring pressure in diagnostic and interventional procedures. Only offered by Philips, iFR Co-registration maps the physiologic measurements directly onto the angiogram enabling more complete procedural guidance. No other resting index has an ESC and ACC/AHA/SCAI Class IA recommendation based on the high level of clinical evidence for its accuracy. Philips iFR is the Gold Standard.1,2
Demonstrated results
Only iFR has Co-registration for advanced physiologic guidance
Map iFR values directly onto the angiogram so you can see which parts of a vessel are causing ischemia. With iFR Co-registration there is no need for hyperemic drugs. You can automatically co-register values in seconds onto the angiogram.
- Better discern focal, serial or diffuse disease6
- Determine precise lesion severity and location7,8
- Make length measurements without a cumbersome pullback device6
- Estimate the physiologic impact of a virtual stent6
iFR Co-registration is available on the new Philips IntraSight interventional applications platform and as an upgrade to the Core systems.
iFR Pullback technology7
iFR Pullback technology reveals the physiologic profile of the entire vessel, so when you encounter diffuse disease or serial lesions you can make informed treatment decisions.
Provides beat-by-beat iFR pressure measurements across the entire vessel, artery-by-artery
Establishes the physiological significance of each vessel and/or individual lesion (focal or diffuse)
Provides a clear view of the functional gain
Virtually plan your PCI and predict results
Angiography provides a visual picture, but often lacks the detail needed for optimal PCI planning. Only Philips provides advanced physiologic guidance to help you determine not just whether to treat, but also where to treat, ensuring precise, patient-focused care.
1. Identify the precise locations causing ischemia - each yellow dot signifies a 0.01 drop of iFR
2. Plan your treatment, before a stent is even placed, with a virtual stent
3. Determine lesion lengths without need for a pullback device
4. Predict physiologic gain with iFR Estimate to determine the best treatment strategies

- Philips physiology wires enable measurement of both FFR and iFR, both supported by key industry guidelines including ESC Class IA designation.5
- Obtain easy length measurements that combine IVUS and iFR information with the angiogram to help determine if a stent will meet the procedural objectives
