Comparison of MRI and CT for Detection of Acute Intracerebral Hemorrhage

JAMA. 2005;293(5):550-551. doi:10.1001/jama.293.5.550-a

To the Editor: In their study comparing magnetic resonance imaging (MRI) and computed tomography (CT) for detection of acute intracerebral hemorrhage in patients presenting with acute stroke symptoms,1 Dr Kidwell and colleagues concluded that the 2 methods have equivalent accuracy. Although the reported level of raw agreement of 96% was very high, we believe that an alternate statistical approach would have been more appropriate and would have resulted in a more conservative level of agreement.
