Compared with CT,MR detected a few more ischemic infarcts,hemorrhagic infarcts,meningeal enhancement and granulomas in the acute meningitis group,but missed small calcifications in the basal cisterns well shown on CT in the sequelae group.Otherwise,MR generally matched CT scans.MR imaging appears to be superior to CT in evaluation of active intracranial Tb only if Gd-DTPA is used,while CT is better than MR in evaluating meningitic sequelae with calcification. |
