Overview
When a stroke has been diagnosed, various other studies may be performed to determine the underlying etiology. With the current treatment and diagnosis options available, it is of particular importance to determine whether there is a peripheral source of emboli. Test selection may vary, since the cause of stroke varies with age, comorbidity and the clinical presentation. An angiogram of the cerebral vasculature (if a bleed is thought to have originated from an aneurysm or arteriovenous malformation)
Other Imaging Studies
Other imaging studies which may help diagnose the cause and risk factors of ischemic stroke may include:[1]
CT angiography
- May help determine the qualitative cerebral blood flow volume to the area surrounding the infarct tissue and can determine the risk of future infarct. [2][3][4][5]
- May help diagnose basilar artery thrombosis and acute large intracranial thrombosis
MR angiography
- May help diagnose basilar artery thrombosis and large intracranial thrombosis
SPECT scan
Digital subtraction angiography
- May help diagnose collateral flow in cases of ischemic stroke.
- May be beneficial in diiagnosis of basilar artery thrombosis.
Positron emission tomography
Arterial spin labelling
- May help diagnose the presence of collateral blood flow
