This is a prospective study including acute ischemic stroke patients aged 18 to 90. Multidetector raw CT is performed in acute ischemic stroke patients. Heart, neck vessels and brain arteries are studied during the same acquisition. Results are compared with the standard methods including transesophageal echocardiography (TEE), Doppler ultrasound (DUS) and MR angiography (MRA) of neck vessels. The main criteria is the ability of CT to classify the stroke etiology correctly according to the TOAST classification in comparison with the standard methods.

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:
  • Ability of CT to classify the stroke etiology correctly (TOAST classification) in comparison to reference methods (MRA, DUS, TEE) [ Time Frame: classify the stroke etiology ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Ability of CT to detect the source of stroke in each etiological group. Reliability of CT in quantitative measures of artery stenosis, aortic atheroma, heart thrombus, heart tumors). Tolerance of CT [ Time Frame: detect the source of stroke ] [ Designated as safety issue: No ]
