Use validated decision rule to determine need
Avoid CT in patients with minor head injury who are at low risk based on validated decision rules.

Diagnostic approach for ICH
A baseline severity score should be performed as part of the initial evaluation of patients with ICH (Class I; Level of Evidence B)
Rapid neuroimaging with CT or MRI is recommended to distinguish ischemic stroke from ICH (Class I; Level of Evidence A)
CTA and contrast-enhanced CT may be considered to help identify patients at risk for hematoma expansion (Class IIb; Level of Evidence B), and CTA, CT venography, contrast-enhanced CT, contrastenhanced MRI, magnetic resonance angiography and magnetic resonance venography, and catheter angiography can be useful to evaluate for underlying structural lesions including vascular malformations and tumors when there is clinical or radiological suspicion (Class IIa; Level of Evidence B).

ECG role (elevated<unk>  pressure)
Diffuse T-wave inversions
Prolonged QT
Bradycardia (the Cushing reflex – indicates imminent brainstem herniation)
Other possible ECG changes that may be seen:
ST segment elevation / depression — this may mimic myocardial ischaemia or pericarditis.
Increased U wave amplitude.
Other rhythm disturbances: sinus tachycardia, junctional rhythms, premature ventricular contractions, atrial fibrillation.
