T1-weighted fluid-attenuated inversion recovery and T1-weighted fast spin-echo contrast-enhanced imaging: a comparison in 20 patients with brain lesions.

T1-weighted fluid-attenuated inversion recovery (FLAIR) sequence is a relatively new pulse sequence for intracranial MR imaging. This study was performed to compare the image quality of T1-weighted FLAIR with the T1-weighted FSE sequence. Twenty patients with brain lesions underwent T1-weighted fast spin-echo (FSE) and T1-weighted FLAIR during the same imaging session.

Epilepsy in a young adult caused by L-2-hydroxyglutaric aciduria: a case report.

Objective: To report the importance of a rare organic acid metabolic disorder, L-2-hydroxyglutaric aciduria, and its characteristic neuroimaging cerebral white matter abnormalities in a case of epilepsy.

Subject And Methods: A 19-year-old male presented with an 11-year history consisting of school failures, intellectual deterioration and generalized tonic-clonic convulsions.

Results: Neurological examination showed mental subnormality, mild dysarthria and bilateral pyramidal signs.

Intrathecal gadolinium (gadopentetate dimeglumine) enhanced magnetic resonance myelography and cisternography: results of a multicenter study.

Rationale And Objectives: This cooperative multicenter human study was designed to evaluate the safety, magnetic resonance (MR) imaging characteristics, and clinical response to a single gadolinium contrast agent: gadopentetate dimeglumine.

Material And Methods: Ninety-five patients (age range: 1 month to 78 years; sex: 50 males, 45 females) were included in this prospective study. The patients presented clinically with a variety of cranial or spinal signs and symptoms for which an intrathecal contrast myelogram or cisternogram was requested by clinical staff.

Intrathecal gadolinium-enhanced MR cisternography in the evaluation of clinically suspected cerebrospinal fluid rhinorrhea in humans: early experience.

In this prospective multicenter study, the authors evaluated the utility of magnetic resonance (MR) cisternography after intrathecal administration of gadopentetate dimeglumine in 15 patients clinically suspected of having cerebrospinal fluid (CSF) rhinorrhea. By means of lumbar puncture, a single dose of 0.5 mL of gadopentetate dimeglumine was injected into the lumbar subarachnoid space.

Fucosidosis: immunological studies and chronological neuroradiological changes.

A 3.5-y-old boy of Arabic origin had the clinical features of both type 1 and type 2 fucosidosis, consistent with an intermediate form of the disease. The activity of his leucocyte alpha L-fucosidase was absent.
