BACKGROUND: The relation between abnormalities in the lumbar spine and low back pain is controversial. We examined the prevalence of abnormal findings on magnetic resonance imaging (MRI) scans of the lumbar spine in people without back pain.

METHODS: We performed MRI examinations on 98 asymptomatic people. The scans were read independently by two neuroradiologists who did not know the clinical status of the subjects. To reduce the possibility of bias in interpreting the studies, abnormal ...

PURPOSE: To prospectively determine in patients with acute low back pain (LBP) or radiculopathy, the magnetic resonance (MR) imaging findings, prognostic role of these findings, and effect of diagnostic information on outcome.

MATERIALS AND METHODS: Institutional review board approval and informed consent were obtained. This study was HIPAA compliant. A total of 246 patients with acute-onset LBP or radiculopathy were randomized to either the early information arm of the study, with MR ...

The purpose of this study was to investigate the presence of any correlation between recurrent radicular pain during the first six months following first surgery for herniated lumbar intervertebral disc and the amount of lumbar peridural fibrosis as defined by MR imaging. 197 patients who underwent first-time single-level unilateral discectomy for lumbar disc herniation were evaluated in a randomized, double-blind, controlled multicenter clinical trial. Clinical assessments, performed by ...

BACKGROUND AND PURPOSE: Mental imagery involves rehearsing or practicing a task in the mind with no physical movement. The technique is commonly used, but the actual physical foundation of imagery has not been evaluated for the fast, complex, automatic motor movement of the golf swing. This study evaluated motor imagery of the golf swing, of golfers of various handicaps, by using functional MR imaging to assess whether areas of brain activation could be defined by this technique and to ...

BACKGROUND CONTEXT: The presence or absence of marrow edema is used in the assessment of fracture acuity in magnetic resonance imaging (MRI). We have observed variability in the degree of marrow edema in acute trauma. Our aim was to characterize the utility of marrow edema in fracture detection and fracture acuity on MRI. We hypothesized that only vertebral body compression injuries reliably generate marrow edema and that distraction injuries or fractures without compression do not ...

OBJECTIVE: Stereotactic radiosurgery has been used increasingly for the treatment of glomus jugulare tumors. The authors report their experience treating these tumors using gamma knife radiosurgery (GKRS), documenting the clinical and radiological outcome.

METHODS: A retrospective analysis identified 17 patients with glomus jugulare tumors who underwent GKRS. Besides analysis of clinical outcome, a radiological volumetric analysis was also performed after treatment.

RESULTS: There were ...

BACKGROUND AND PURPOSE: The treatment algorithm for acute cerebrovascular accidents has traditionally sorted these accidents as either hemorrhagic or nonhemorrhagic, and MR imaging, with its ability to allow expeditious assessment of vascular substrates and regional blood volume, is well suited for this purpose. Our purpose was to delineate the accuracy of MR imaging in acute, hemorrhagic forms of stroke during the time frame considered beneficial for intervention in an animal ...
