How this service works
PRE (Pittsburgh Response to Endovascular therapy) score: age + 2×NIHSS - 10×ASPECTS (Rangaraju 2015). Integer PRE, quartiles <0 / 0-24 / 25-49 / >=50, and recanalization-benefit strata <-24 / -24 to 49 / >=50. Not a thrombectomy recommendation. The caller assigns NIHSS and ASPECTS; magent does not assign NIHSS or read CT.
Output
Returns an integer PRE score (age + 2×NIHSS − 10×ASPECTS), a quartile classification (less than 0 / 0–24 / 25–49 / 50 or above), and a recanalization-benefit stratum (less than −24 / −24 to 49 / 50 or above). Does not constitute a thrombectomy recommendation.
Example use cases
Acute stroke triage decision support
“I have a 74-year-old patient presenting with acute ischemic stroke — the team has scored NIHSS at 22 and ASPECTS at 6. Can you compute the PRE score and tell me the quartile and recanalization-benefit stratum?”
Retrospective stroke cohort analysis
“For our quality review, calculate the PRE score for a 58-year-old with NIHSS 14 and ASPECTS 9 and classify them by quartile and recanalization-benefit stratum.”
Clinical education case illustration
“We're teaching residents about the Rangaraju 2015 PRE formula. Can you run the calculation for a hypothetical 80-year-old patient with NIHSS 20 and ASPECTS 5 and show the score, quartile, and benefit stratum?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/pre_scoreWhen to prefer
Use this endpoint when you need a fast, reproducible computation of the Rangaraju 2015 PRE score from caller-supplied NIHSS and ASPECTS values. It is the right choice for clinical documentation workflows, retrospective cohort analysis, or educational tooling where the score and stratum need to be calculated programmatically without manual arithmetic. Do not use it as a replacement for clinical judgment or as a thrombectomy recommendation system.
Side effects
- Missing required query parameters (age, nihss, or aspects) returns a validation error
- Out-of-range values (e.g. age <18 or >120, NIHSS >42, ASPECTS >10) may return an error or unexpected result
- Payment failure (x402) if USDC balance or authorization is insufficient
- Network timeout or server unavailability returns HTTP 5xx
