BACKGROUND AND PURPOSE Laboratory studies have been used to identify nitric oxide as a notable mediator in neuronal death after acute brain injury. To our knowledge, this has not previously been confirmed with in vivo study in humans. Our purpose was to seek in vivo evidence for the induction of nitric oxide synthase (NOS) in human acute brain injury by(More)
The kicking action predominantly used in Australian Rules football is considered to be responsible for many lower limb injuries. The aim of this study was to describe a non-invasive method of identifying the thigh muscles involved in kicking an Australian Rules football, using MRI. Both upper thighs of 10 recreational footballers were examined using a 1.5-T(More)
PURPOSE 1) To determine whether MR appearances of the spinal cord in acute trauma correlate with clinical prognosis, and 2) to identify other MR and CT prognostic factors in acute spinal trauma. METHODS Retrospective evaluation of MR, CT, and clinical examinations in 32 acute spinal trauma patients examined between 1987 and 1990. RESULTS All 21 patients(More)
The plantar plate is the fibrocartilaginous structure that supports the ball of the foot, withstanding considerable compressive and tensile forces. This study describes the morphology of the plantar plate in order to understand its function and the pathologic disorders associated with it. Eight lesser metatarsophalangeal joint plantar plates from three(More)
In a prospective comparison between fast magnetic resonance imaging (MRI) sequences and conventional spin-echo in a series of 20 patients, gradient-echo imaging was found to be inferior to spin-echo, especially in the visualization of spinal cord oedema, and the use of a rapid spin-echo sequence was limited by inferior visualization of haemorrhage. While(More)
The presence, location and number of Schmorl's nodes was determined in the thoracolumbar spines of 70 motor vehicle accident victims using radiographic examination of a midline sagittal section and subsequent pathological examinations, including histology. In 28% of spines, a greater number of Schmorl's nodes were identified with radiography, while in 44%,(More)
Five cases are presented in which subarachnoid haemorrhage (SAH) was diagnosed by clinicians and/or radiologists on computed tomography (CT) scan. No macroscopic SAH was present on neuropathologic examination. In retrospect it was considered that the neurologic signs and the neuropathologic features close to the time of CT scan were in keeping with the(More)
PURPOSE To 1) correlate spinal MR features and modes of clinical presentation associated with symptomatic neurologic deterioration following longstanding spinal trauma; 2) correlate degree of neurologic deficit with spinal MR appearance in these patients; and 3) determine the relationship between new symptoms and ongoing cord compression. METHODS(More)
The variable magnetic resonance imaging appearances of central nervous system haemorrhage, both intra- and extra-axial, are described. These will vary with the type of image contrast (T1 or T2 weighting), the nature of the imaging sequence (spin-echo or gradient-echo) and the time from onset of haemorrhage. Magnetic resonance imaging is a useful technique(More)
