25. Investigations in acute stroke: Diagnostic question Investigation Is it a vascular lesion? CT/MRI Is it ischaemic or haemorrhagic? CT/MRI Is it a subarachnoid haemorrhage? CT Lumbar puncture Is there any cardiac source of embolism? Electrocardiogram (ECG) Echocardiogram What is the underlying vascular disease? Duplex ultrasound of carotids Magnetic resonance angiography (MRA) CT angiography (CTA) Contrast angiography What are the risk factors? Full blood count Cholesterol Blood glucose Is there an unusual cause? ESR Clotting/thrombophilia screen
