title: Arnold-Chiari malformation detected by unenhanced multiplanar CT scan.
abstract: Multiplanar computed tomographic (CT) scanning done without injection of contrast agent detected the nervous tissue abnormalities in 4 patients with Arnold-Chiari Malformation. Comparisons were made between traditional radiological studies and CT scanning. Three cases were confirmed surgically; the fourth case was diagnosed purely by CT scanning. This preliminary study suggests that this new technique should be sufficient to make a positive diagnosis in most cases of Arnold-Chiari malformation.
