Magnetic Resonance Imaging of Intracranial Meningiomas: A Comparative Analysis of Histological and Magnetic Resonance Features

Significant progress in diagnosis of intracranial tumors has been made during the past decade. In the late 1970s, computed tomography (CT) became an established technique in neuroimaging, which had proven its diagnostic potential especially in regard to intracranial tumors [5]. In the early 1980s, magnetic resonance (MR) imaging was introduced into clinical practice [1]. Although MR is widely used nowadays and advances have been tremendous, a lot of difficulties still remain in interpreting MR data [1]. The correlation between histological diagnoses and tissue dignity on the one hand and ϱ, T1, and T2 parameters on the other hand is one area in which knowledge is limited [3, 4]: first results seem to be less promising than was hoped for at the beginning of the MR period [3, 4]. For these reasons, we reviewed some of our meningioma cases that were studied with MR and compared the very variable histological pattern of these tumors with their heterogeneous MR characteristics.
