Radiographic osteoarthrosis in the acromioclavicular joint resulting from manual work or exposure to vibration.

The hypothesis that manual work and exposure to vibration are antecedents to the development of osteoarthrosis was assessed employing a cross sectional study design. The frequency of osteoarthrosis in the acromioclavicular joint was studied in three groups of workers in the construction industry. Two groups were manual workers (54 bricklayers and 55 rock blasters); the third group consisted of 98 foremen.

MRI in psychiatry: 731 cases.

The frequency of brain pathology found in the 731 patients who underwent MRI scans in the present study was higher than expected on the basis of reports in the literature (Owens et al., 1980). This underlines the value of a simple MRI examination as an effective diagnostic complement in the investigation of patients with psychiatric symptoms that may have an underlying organic basis.

Visual rating of magnetic resonance images of human cerebrospinal fluid spaces and white brain matter: relation to sex and age in healthy volunteers.

The size of the cerebrospinal fluid spaces and the occurrence of white matter lesions were estimated from the intracranial volumes of 76 apparently healthy adult volunteers of different ages using 0.02-T/0.8-MHz magnetic resonance imaging.

Diminished space in the acromioclavicular joint in forced arm adduction as a radiographic sign of degeneration and osteoarthrosis.

The purpose of this study was to examine the acromioclavicular joint by radiography under forced arm adduction to demonstrate diminished joint space as a sign of cartilage degeneration and osteoarthrosis. A total of 192 right and left joints were investigated in 96 healthy working men. There were three main results from the manoeuvre: in 135 of the 192 joints the space was reduced, in 33 joints it was unchanged, and in 24 joints the joint space was increased.

Low field magnetic resonance imaging of the central nervous system in 15 children with autistic disorder.

Fifteen children, 10 boys and 5 girls, with autistic disorder, were studied with low field magnetic resonance imaging (MRI). The age ranged from 2.7-13.
