There are two widely used transient middle cerebral artery occlusion (MCAO) methods, which differ in the use of unilateral or bilateral carotid artery reperfusion (UNICAR and BICAR). Of the two methods, UNICAR is easier to perform. This study was designed to comprehensively compare the two reperfusion methods to determine if there are any differences in(More)
OBJECTIVE Preoperative differentiation between primary central nervous system lymphoma (PCNSL) and high grade astrocytoma (HGA) on conventional magnetic resonance imaging (MRI) can be difficult and even impossible. However, differentiation is important to guide therapeutic strategy. Several authors have reported the leakage pattern in dynamic(More)
INTRODUCTION Regarding therapy and prognosis of acute ischemic stroke the identification of ischemic penumbra is pivotal. A promising candidate is BOLD-imaging using qT2'-maps. For valid interpretation of experimental studies in animals normal values for qT2' are needed. Normal values in humans at 1.5T already exist. Normal values for cortical and(More)
Functional MRI (fMRI) is routinely used to depict language areas, for example in the preoperative diagnostic work-up of patients with a brain tumour. The objective of this study was to test whether semantic decision making can activate the temporo-parietal language areas better than phonological generation stimuli. Five fMRI language stimuli were tested in(More)
OBJECTIVES It is well known that cerebral cavernous malformations (CCMs) present with variable degrees of contrast enhancement on routine magnetic resonance imaging (MRI) studies. This is attributed to the presence of a low flow vascular architecture in these lesions. The aim of this preliminary study was to determine whether an additional reason for the(More)
