x402
ASPECTS Score Calculator (Barber 2000) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes the Alberta Stroke Program Early CT Score (ASPECTS) by subtracting 1 from 10 for each of the 10 MCA regions where the caller reports early ischemic change

How this service works
Barber 2000 ASPECTS: 10 minus 1 for each caller-assigned MCA region with early ischemic change (C caudate, L lentiform, IC internal capsule, I insular ribbon, M1–M6). Score 0–10. Not pc-ASPECTS. magent does not read the CT. Not a diagnosis, lytic order, or medical device.
Output
Returns a single integer ASPECTS score from 0 to 10, computed as 10 minus 1 for each of the 10 caller-assigned MCA regions flagged as showing early ischemic change. A score of 10 means no involvement; 0 means all regions involved. Note: the API does not interpret CT images — all region flags must be determined and provided by the caller.
Example use cases
Acute stroke CT triage scoring
“I've reviewed the CT head and found early ischemic changes in M1 and M2 — all other ASPECTS regions (caudate, lentiform, internal capsule, insular ribbon, M3, M4, M5, M6) are clear. What's the ASPECTS score?”
Large territory infarct documentation
“A patient has early ischemic changes in M1, M2, M3, caudate, and lentiform nucleus, with all other MCA regions (internal capsule, insular ribbon, M4, M5, M6) unaffected. Can you give me the ASPECTS score?”
Borderline thrombolysis candidate scoring
“For a potential tPA candidate I need the ASPECTS score — changes are present only in the insular ribbon, everything else (caudate, lentiform, internal capsule, M1 through M6) looks normal.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/aspectsWhen to prefer
Use this endpoint when you have already clinically reviewed a non-contrast CT head and determined which of the 10 standard Barber 2000 MCA regions show early ischemic change, and need a validated ASPECTS integer score quickly. It is not a substitute for radiologist CT interpretation and does not implement posterior circulation ASPECTS (pc-ASPECTS).
Side effects
- Missing any of the 10 required boolean query parameters returns an error
- Non-boolean values for region flags cause a validation error
- Network or payment (x402) failure results in no score returned
- Caller misassigns regions — API cannot detect or correct CT misinterpretation
