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.
