Acute Stroke

Stroke is a disease caused by disorder of the blood flow to part of the brain because of occlusion(ischemic) of a blood or damage of a blood vessel, causing hemorrhage. For early detection of acute stroke, it’s better to use CT scan because it has a lot of advantages. The use of computed tomography (CT) for stroke evaluation has riced, moreover , CT is quick than MRI. Recently there are CT techniques like perfusion CT and CT angiography that combined with non-enhanced CT that help the physicians to put them to international protocol of CT stroke. To save the stroke patient within the golden hours , The stroke team in the hospital ( on call physicians) must be ready and everything should be prepared for when the patient arrives to the hospital.
Code stroke should be activated to let the emergency department CT be available and ready. International CT stroke protocol should be applied to the patient, first the radiographers with the physicians should do a CT without contrast (non-enhanced) to see if there is any hemorrhage or not. If they did not see any bleeding , they should activate the bolus (power injector) to introduce the contrast in the intravenous which called CT perfusion to detect an ischemic stroke followed by CT angiography to find if there is a thrombosis.
To tide up, The on-call radiologist should manage a patients who has of acute stroke. A new technique of CT study (non-enhanced CT, perfusion CT, and CT angiography) should be obtained and analyzed quickly and easily by general radiologists using an international CT protocol.
