Several neuroradiological techniques can be used to assess ischaemic stroke patients. At facilities where thrombolytic therapies are available, the ideal diagnostic workup in the hyperacute phase is a morphological and functional MR study associated with MRA sequences. However, where this is not feasible (because these techniques are not available, the patient has come to observation in a late phase or is particularly restless, or, signally, a thrombolytic therapy is not indicated), the basic method is CT with serial follow-up studies to monitor disease evolution and the possible complications. At a later time, when this is possible, a conventional MR study with MRA sequences should be performed.
