Detecting pathology
5 check areas
Extra-axial – Bleeds + Collections – Extradural, subdural,and subarachnoid, meningiomas
Intraxial – Masses, oedema, haemorrhage
Basal cisterns and ventricles – Mass effect (midline shift, compressed ventricles), Hydrocephalus, occult subarachnoid blood
Blood vessels
Bones – Fractures, acoustic neuromas
