Rapid CTP automatically delivers quantified and color-coded CT perfusion maps that help physicians quickly assess salvageable brain tissue—enabling faster clinical decisions that facilitate better patient outcomes.
The mismatch map provides a comparison between brain regions with substantial reductions in cerebral blood flow (CBF) in pink and regions with significant hypoperfusion in green as reflected by delays in contrast arrival times (Tmax delays).
The mismatch map can also be configured to show if a patient meets imaging criteria for mechanical thrombectomy.
This map shows the severity of the delays in contrast arrival times (Tmax), the volume of tissue with delays, and the Hypoperfusion Intensity Ratio (HIR) which is automatically calculated.
This map offers a co-registered view of the CT scan with the CT perfusion maps. No thresholds are applied and no volumes are calculated on this map. It provides a comparison between CT findings and the perfusion images.
The AIF plot displays the location automatically chosen by the software for the arterial input function (AIF) and the venous output function (VOF). The movement plots document how much patient movement occurred during the scan.
Rapid CTP provides cerebral blood volume (CBV) thresholds which include a CBV index.
Rapid CTP provides CBF thresholds which include a 20% “golden hour” threshold often used for patients who arrive at the hospital within 60 minutes of symptom onset.
"Rapid directly in the angio suite will help our specialists treat the right patients even faster. Having the most advanced RAPID technology available in both the radiology department and the operating theater provides the best options for our doctors and patients"
"Strokes are a medical emergency, and urgent treatment is essential. However, only about 19% of patients arrive at our hospitals within 4-6 hours after experiencing stroke symptoms. The Rapid technology provides physicians and stroke teams the ability to diagnose more stroke patients by extending the treatment window up to 24 hours. Moving forward our teams will be able to utilize this advanced technology via the Rapid platform to promptly address more cases with the highest efficiency."
