BACKGROUND Magnetic resonance imaging (MRI) is the standard method for observing brain plaques and contrast material injection is necessary for demonstrating the active plaque.This study compared the rate of enhancement of plaques with Gadovist and Magnevist in relapse phase of MS. METHODS In this double blind study, after neurological examination of 62 patients in the attack phase of MS, two...

OBJECTIVE To compare the accuracy of formula 1/2ABC with 2/3SH on volume estimation for hypertensive infratentorial hematoma. METHODS One hundred and forty-seven CT scans diagnosed as hypertensive infratentorial hemorrhage were reviewed. Based on the shape, hematomas were categorized as regular or irregular. Multilobular was defined as a special shape of irregular. Hematoma volume was calcula...

In children, tumours of the central nervous system comprise 20% of all tumours and are second most common after leukaemia. Unlike adults, almost half of all the paediatric brain tumours are in the Infratentorial region as shown in table 1. In the infratentorial region, the common tumours are medulloblastoma, low grade cerebellar astrocytoma, brain stem glioma and ependymoma. In the supratentori...

BACKGROUND AND PURPOSE Subdural hemorrhage (SDH) is often associated with infants experiencing nonaccidental injury (NAI). A study of the appearance and natural evolution of these birth-related hemorrhages, particularly SDH, is important in the forensic evaluation of NAI. The purpose of this study was to determine the normal incidence, size, distribution, and natural history of SDH in asymptoma...

DWI reportedly accurately differentiates pediatric posterior fossa tumors, but anecdotal experience suggests limitations. In 3 years, medulloblastoma and JPA were differentiated by DWI alone in 23/26 cases (88%). Ependymoma (n = 5) could not be reliably differentiated from medulloblastoma or JPA. A trend toward increased diffusion restriction in higher grade tumors (1/14 grade I, 7%; 9/12 grade...
