Magnetic resonance imaging (MRI) has some advantages in stroke diagnosis. In a Lancet study, MRI accurately diagnosed 83% of acute strokes (that is, strokes in progress), while computed tomography (CT) scans diagnosed only 26%.Still, MRI is unlikely to replace CT scans for speedy diagnosis of acute stroke anytime soon.For one thing, while most emergency departments can quickly order a CT scan for suspected stroke patients, fewer have rapid access to MRI. MRI is also more expensive than CT and takes longer to do.till, MRI is unlikely to replace CT scans for speedy diagnosis of acute stroke anytime soon.
