    Cerebrospinal fluid flow and production in patients with normal pressure hydrocephalus studied by MRI

    An interleaved velocity-sensitised fast low-angle shot pulse sequence was used to study cerebrospinal fluid (CSF) flow in the cerebral aqueduct, and supratentorial CSF production in 9 patients with normal pres...

    Absence of Hydrocephalus in Spite of Impaired Cerebrospinal Fluid Absorption and Severe Intracranial Hypertension

    In the paper we have described four patients presenting papilledema, increased pressure and reduced CSF absorption, either caused by spinal tumours, leptomeningeal carcinomatosis or chronic encephalitis. All t...

    Brain Water Accumulation in Pseudotumour Cerebri Demonstrated by MR-imaging of Brain Water Self-Diffusion

    We studied brain water self diffusion in pseudotumour cerebri by MR-imaging using single spin echo pulse sequences with pulsed magnetic field gradients of different magnitude. The methods is based on the fact ...

    Resistance to Cerebrospinal Fluid Outflow and Intracranial Pressure in Patients with Hydrocephalus after Subarachnoid Haemorrhage

    Resistance to CSF-outflow (Rout) and intracranial pressure (ICP) were measured in 33 patients with hydrocephalus after subarachnoid haemorrhage (SAH). Eleven patients examined between 10 to 30 days after SAH had ...

    The Acute Effect of Nimodipine on Intracranial Pressure and Cerebral Blood Flow

    In acute stroke it has been shown that the calcium antagonist PY 108-068 induces a slight increase in mean cerebral blood flow (CBF) in some cases with a concomitant flow reduction in focal ischemic areas [8]....

    Unbiased and efficient estimation of total ventricular volume of the brain obtained from CT-scans by a stereological method

    Using a simple stereological method the estimation of the ventricular volume in ten hydrocephalic children and adults based on ordinary CT-scans is presented. The volume estimates are compared with “ventricula...
