CONCLUSION Thanks for the answer. The correct answer is vascular imaging of extra cranial and intracranial arteries. A diagnosis of embolic stroke of undetermined sourse requires a minimum diagnostic assessment including CT or MRI demonstrating nonlacunar stroke,vascular imaging excluding extracranial or intracranial atherosclerosis stenosis in vessels supplying the area of ischemia or other specific cause of stroke( eg dissection),transthoracic echocardiogram ,and cardiac rhythm monitoring for at least 24 hrs.

D- dimer Assay.
