@Swaiyam That's what I meant, but obviously it's not a stylistic issue here.

There are no prior examinations available ...

Swaiyam, CCT does provide some information about the age of an ischemic lesion, except for the very first hours after the insult where CCT is much less sensitive than MRI. In particular, old lesions are clearly demarcated while the boundaries of newer lesions are blurred (up to the point of being just vaguely perceivable to the trained eye in fresh lesions). <br />The point here seems to be that there are lesions present. While the examiner cannot rely on previous imaging to define their age, he/she seems to be saying that none of the lesions shows a demarcation pattern of a fresh or recent insult (which is, of course, a less sensitive and less reliable method of defining age than a comparison with recent previous images.)

There are no previous examinations to compare (results with), no recently demarcated insult.
