MR angiography of arteriovenous malformations: usefulness of phase-contrast with different velocity encoding
To evaluate the usefulness of MR angiography in arteriovenous malformations (AVM) and compare the phase-contrast (PC) with different velocity encoding (VENC) and time-of-flight (TOF) techniques, we prospective...

MRI of intracranial germ cell tumors
We reviewed MRI findings in proven intracranial germ cell tumours in 22 cases, 12 of whom received Gd-DTPA. On T1-weighted images, the signal intensity of the tumour parenchyma was moderately low in 19 cases a...

Utility of MR angiography in intracranial aneurysms: statistical correlation and surgical benefits of the 3-D time-of-flight method
We evaluated the clinical benefit of three-dimensional (3-D) time-of-flight (TOF) MR angiography (MRA) and spoiled GRASS (SPGR) source imaging for intracranial aneurysms. MRA was performed on 40 aneurysms conf...

Core-Level Spectroscopy in Early-Transition-Metal Compounds
We analyse theoretically X-ray photoemission spectra (XPS) and X-ray absorption spectra (XAS) of early transition metal compounds with cluster model. From the analysis of Ti 1s and 2p XAS and Ti 2p, 3s, 3p XPS of...

Construction of squalene-accumulatingSaccharomyces cerevisiae mutants by gene disruption through homologous recombination
Saccharomyces cerevisiae synthesizes ergosterol via squalene, but squalene is hardly detected in aerobically grown cells. To obtain a stable squalene-accumulating yeast strain, we attempted to disrupt a gene req...

Displacement of the normal pituitary gland by sellar and juxtasellar tumours: surgical-MRI correlation and use in differential diagnosis
We compared the position of the normal pituitary gland as estimated by gadolinium (Gd)-DTPA-enhanced MRI, with its position at surgery in 40 patients with intra- and juxtasellar tumours: 22 pituitary adenomas,...

MRI of pituitary adenomas: the position of the normal pituitary gland
The position of the normal pituitary gland, assessed using gadolinium-enhanced MRI was compared with the position found at surgery for pituitary adenoma in 25 patients. The tumours were five microadenomas and ...

MRI visualization of complete bilateral optic nerve involvement by pituitary adenoma: a case report
With large pituitary adenomas, the optic nerves and chiasm usually lie on the tumour capsule and are displaced superiorly. We report a large invasive pituitary adenoma, with complete involvement of both optic ...

Hyperaemia prior to acute cerebral swelling in severe head injuries: The role of transcranial doppler monitoring
Acute cerebrovascular congestion after a closed head injury is significantly related to intracranial hypertension. As an indirect method of cerebral blood flow measurement, transcranial doppler sonography (TCD...

Pathophysiological Studies in the Rat Cerebral Embolization Model: Measurement of Epidural Pressure and Evaluation of Tissue pH and ATP
A rat embolization model was produced by occlusion of the main cerebral artery with a silicone cylinder embolus. Intracranial pressure was monitored by changes in epidural pressure (EDP), which was recorded by...

Statistical Analysis of Changes in Topographic EEG on Brain Tumor Cases with Peritumoral Edema
EEG is one of the best methods for estimating brain function. Topographic EEG is made by analyzing the power spectrum of EEG as equivalent potential (EP). In this study, the changes in topographic EEG after gl...
