Patients who have received recent thrombolysis or are critically ill from stroke are probably not well suited for MRI, because they cannot be monitored by clinical examinations during the period of imaging. If MRI is essential, it should be performed with the bare minimum of sequences required to make the diagnosis, such as T1-, T2-, diffusion-, or perfusion-weighted imaging and MRA. Many institutions have established acute stroke protocols to minimize scanning time.
