How this service works
Greving 2014 PHASES 5-year rupture risk for an unruptured intracranial aneurysm. Caller assigns population (north_america_europe 0, japanese 3, finnish 5), hypertension (1), age >=70 (1), size mm (<7 0, 7.0-9.9 3, 10.0-19.9 6, >=20 10), earlier SAH (1), and site (ica 0, mca 2, aca_pcom_posterior 4). Returns points (max 22) and grouped 5-year risk percent. Not a treatment order or PHASES of care. magent does not assign ancestry or read imaging.
Output
Returns the total PHASES integer score (0–22) derived from the six weighted inputs, plus the corresponding grouped 5-year rupture risk percentage as defined by Greving 2014. Does not produce treatment recommendations or imaging interpretation.
Example use cases
Neurology clinic pre-surgical risk review
“I need the PHASES score for a 72-year-old Finnish patient with hypertension, no prior SAH, and an 8.5mm posterior communicating artery aneurysm — what is the estimated 5-year rupture risk?”
Second opinion for watchful-waiting decision
“Run the Greving 2014 PHASES score for a 65-year-old North American patient, no hypertension, no prior SAH, 6mm ICA aneurysm — give me the total points and 5-year risk group.”
Comparative risk scoring across aneurysm sizes
“What's the PHASES score and 5-year rupture risk for a Japanese patient, age 74, hypertensive, with a prior SAH, and a 22mm ACA aneurysm?”

Endpoint
GEThttps://api.magentlab.com/api/calc/phasesWhen to prefer
Use this endpoint when you need a validated, evidence-based 5-year rupture risk estimate for an unruptured intracranial aneurysm following the Greving 2014 PHASES methodology. It is specifically appropriate when the caller can supply all six PHASES inputs (population group, hypertension, age, aneurysm size, prior SAH, site) as discrete values rather than raw clinical notes or imaging. Prefer this over generic risk calculators when the clinical context is neurovascular and the Greving 2014 PHASES rubric is the accepted institutional standard.
Side effects
- Missing required query parameters (population, hypertension, age, aneurysm_mm, earlier_sah, site) returns a 400 error
- Invalid enum value for population or site returns a validation error
- aneurysm_mm outside the accepted range (1.0–50.0) may return an error or be clamped
- age outside integer range 18–120 may be rejected
- Network or payment authorization failure (x402) prevents score retrieval
