    Using a systematic approach when reading a brain CT will make you a better doctor

    Because you only see what you’re looking for. Don’t believe?

    “Blood Can Be Very Bad” 

    • B: blood:

      • Epidural hematoma

      • Subdural hematoma

      • Intraparenchymal hemorrhage

      • Subarachnoid hemorrhage

      • Intraventricular hemorrhage

    • C: cisterns (presence of blood, effacement and asymmetry)

      • Circummesencephalic (ring around the midbrain)

      • Suprasellar (star-shaped, location of circle of Willis)

      • Quadrigeminal (W-shaped at top of midbrain)

      • Sylvian (between temporal and frontal lobes)

    • B: brain

      • Assess for asymmetry or effacement of the sulcal pattern

      • Hypodensities or hyperdensities

      • Gray-white matter differentiation (early sign of ischemic stroke)

    • V: ventricles

      • Hydrocephalus

      • Blood

      • Ventricular effacement /shift

    • B: bone (make sure you change to bone widow)

      • Skull fractures

      • Pneumocephalus
