OBJECT In a prospective study, 28 patients with 32 intracranial meningiomas were examined to determine the role of hydrodynamic interaction between tumor and surrounding brain tissue in the pathogenesis of peritumoral brain edema. METHODS Gadolinium-diethylenetriamine pentaacetic acid (Gd-DPTA), an extracellular contrast agent used for routine clinical(More)
Magnetic resonance perfusion and diffusion studies were undertaken to clarify the significance of ischemia in the pathogenesis of peritumoral brain edema in patients with meningiomas. Included in this study were 26 patients with 27 meningiomas and 5 gliomas. Perfusion-weighted imaging (PWI) was performed using a gradient-echo, echo-planar-imaging (EPI)(More)
A case of mediastinal paraganglioma in association with bilateral carotid body tumors is presented. Characteristic radiological findings included a hypointense signal in T1-weighted, a hyperintense signal in T2-weighted magnetic resonance (MR) images and a vascular enhancement pattern in dynamic contrast enhanced MR imaging. Thus, feeding vessels could be(More)
PURPOSE To study and test the impact of modern MRI techniques in diagnostic imaging in the evaluation of intra-osseous fistulous systems and sequesters. MATERIALS AND METHODS In a prospective study, nine patients with chronic osteomyelitis of the legs were examined by MRI. Patients with clinical signs of osteomyelitis requiring surgery were included in(More)
