Pathologic correlates of incidental MRI white matter signal hyperintensities.

Franz Fazekas, Reinhold Kleinert, +5 authors Helmut Lechner
Neurology
1993

We related the histopathologic changes associated with incidental white matter signal hyperintensities on MRIs from 11 elderly patients (age range, 52 to 82 years) to a descriptive classification for… (More)

Criteria for an increased specificity of MRI interpretation in elderly subjects with suspected multiple sclerosis

Franz Fazekas, Hans Offenbacher, +4 authors Helmut Lechner
Neurology
1988

We reviewed the MRIs of 49 asymptomatic volunteers (age range, 31 to 77 years) and of 50 MS patients (age range, 14 to 63) for areas of increased signal (AIS) and features discriminating MS lesions… (More)

The Mattis Dementia Rating Scale: normative data from 1,001 healthy volunteers.

Reinhold Schmidt, Wolfgang Freidl, +7 authors Helmut Lechner
Neurology
1994

We administered the Mattis Dementia Rating Scale (MDRS) to 1,001 healthy volunteers, aged 50 to 80 years, randomly selected from our community. Multivariate regression analysis revealed educational… (More)

The morphologic correlate of incidental punctate white matter hyperintensities on MR images.

Franz Fazekas, Reinhold Kleinert, +5 authors Helmut Lechner
AJNR. American journal of neuroradiology
1991

Postmortem examinations were made of the brains of six patients, 52-63 years old, who exhibited incidental punctate white matter hyperintensities on MR images before death. Our aim was to unravel the… (More)

Magnetic resonance imaging cerebral abnormalities and neuropsychologic test performance in elderly hypertensive subjects. A case-control study.

Reinhold Schmidt, Franz Fazekas, +5 authors Helmut Lechner
Archives of neurology
1995

OBJECTIVE To search for a morphologic basis of cognitive impairment possibly associated with arterial hypertension using magnetic resonance imaging and a demanding neuropsychologic test battery. … (More)

Magnetic resonance imaging and spectroscopy findings after focal status epilepticus.

Franz Fazekas, Peter Kapeller, +5 authors Helmut Lechner
Epilepsia
1995

The etiology of cerebral abnormalities after focal status epilepticus (SE) is unknown. Possible causes include hypoxia and the excessive release of excitatory amino acids. Magnetic resonance imaging… (More)

Sleep alterations in ischemic stroke.

Eva Koerner, Erich Flooh, +4 authors Helmut Lechner
European neurology
1986

In 19 patients with cerebral infarctions in the middle cerebral artery territory, investigations of sleep using a mobile EEG recording system were performed. Sleep was found to be markedly altered… (More)

Superficial siderosis of the spinal cord: a rare cause of myelopathy diagnosed by MRI.

Hans Offenbacher, Franz Fazekas, Franz Reisecker, Reinhold Schmidt, Franz Payer, Helmut Lechner
Neurology
1991

Repeated bleeding into CSF spaces may cause superficial siderosis with progressive neurologic impairment. The unique physical properties of MRI provide a basis for the in vivo diagnosis of this… (More)

Idiopathic sclerotic inflammation of the orbit with left optic nerve compression in a patient with multifocal fibrosclerosis.

Gottfried J. Schaffler, Josef Simbrunner, +4 authors Franz Ebner
AJNR. American journal of neuroradiology
2000

We present the MR imaging findings in a 43-year-old male patient with bilateral idiopathic sclerosing inflammation of the orbit. Bilateral enhancing retrobulbar masses, with concentric compression of… (More)

Magnetic resonance imaging signal hyperintensities in the deep and subcortical white matter. A comparative study between stroke patients and normal volunteers.

Reinhold Schmidt, Franz Fazekas, +6 authors Helmut Lechner
Archives of neurology
1992

Mixed population studies suggest a relationship between deep and subcortical white matter hyperintensities on magnetic resonance imaging and cerebrovascular disease. To further clarify this issue we… (More)
