ECG
Head CT (non-contrast)
- In ischemia stroke CT has sensitivity 42%, specificity 91%^[1]
- In acute ICH the sensitivity is 95-100%^[2]
- The goal of CTH is to identify stroke mimics (ICH, mass lesions, etc .)^[3]
MRI Brain DWI and cervical vascular imaging predict short-term risk for stroke in patients presenting with suspected TIA^[4]. When feasible, physicians should obtain:
- MRI with DWI/MRA in patients with high short-term risk for stroke (ACEP Level B)
- Carotid US/CTA/MRA in patients with high short-term risk for stroke (ACEP Level B)
  - Carotid US is slightly less sensitive than MRA, but useful for carotid stenosis eval^[5] (ACEP Level C)
Also consider:
- Pregnancy test
- CXR (if infection suspected)
- UA (if infection suspected)
- Utox (if ingestion suspected)
