How this service works
Khan 2020 modified Brain Injury Guidelines (mBIG), not original Joseph 2014 BIG. First-match worst-wins tier 3 then 2 then 1 from caller-assigned GCS, focal or pupillary abnormality, anticoagulant or antiplatelet excluding aspirin alone, EtOH >80 mg/dL, skull fracture, SDH mm, IPH mm and multiple IPH, SAH pattern and mm, any EDH, and IVH. Any EDH is mBIG 3. magent does not read CT. Adults with mild TBI and traumatic ICH. Not a diagnosis or neurosurgical plan. Not a medical device.
Output
Returns the mBIG tier (1, 2, or 3) computed using Khan 2020 first-match worst-wins logic across the submitted clinical and imaging parameters. Tier 3 is the most severe classification. The result is a clinical score only — not a diagnosis or neurosurgical management plan.
Example use cases
Anticoagulated patient with subdural hematoma
“Run the mBIG score for a mild TBI patient on apixaban: GCS 15, no focal neuro findings, anticoagulated (not just aspirin), no alcohol, no skull fracture, SDH 5 mm, no IPH, no multiple IPH, no SAH, no EDH, no IVH — what tier does that come out to?”
EDH on CT after head trauma
“I have a patient with a mild TBI and an epidural hematoma on CT — GCS 13, no pupillary abnormality, not on anticoagulants, no alcohol, no skull fracture, no SDH, no IPH, no SAH, no IVH. Can you run the mBIG calculator and tell me the tier?”
Multiple IPH with low GCS
“Calculate the Khan 2020 mBIG tier for this case: GCS 12, no focal neuro or pupillary findings, aspirin only (not anticoagulated), blood alcohol >80 mg/dL, no skull fracture, no SDH, IPH 9 mm, multiple IPH present, no SAH, no EDH, no IVH.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/mbigWhen to prefer
Use this endpoint when you need to apply the specific Khan 2020 mBIG criteria to adult mild TBI patients with traumatic intracranial hemorrhage and want an automated, auditable tier classification. Prefer this over general TBI scoring tools when the Khan 2020 mBIG tier specifically is required (e.g., for clinical protocol adherence). Note: this endpoint does not read CT images; all imaging findings must be caller-assigned. Not applicable for pediatric patients or for cases outside mild TBI with traumatic ICH.
Side effects
- Missing required query parameters (gcs, edh, ivh, etc.) returns a 400 or validation error
- GCS value outside integer range 3–15 may cause a validation error
- SDH, IPH, or SAH mm values outside allowed range cause input rejection
- Boolean parameters passed as non-boolean types cause parsing errors
- Payment not completed (x402) results in a 402 Payment Required response
