To evaluate orbital blood flow velocities with Doppler sonography in patients with acute unilateral optic neuritis. ⋯ Peak systolic and end diastolic velocities in the ophthalmic artery are increased in patients with acute optic neuritis.
-
To determine the number of researchers who fulfill the International Committee of Medical Journal Editors (ICMJE) authorship criteria and to evaluate individual contributions. ⋯ The 68% fulfillment of criteria for authorship was closely related to the large number of researchers contributing to one category or to categories belonging to the same ICMJE criterion.
-
To evaluate clinical relevance of high-resolution computed tomographic (CT) findings in patients with bronchiectasis by using a quantitative high-resolution CT protocol to assess extent of bronchiectasis, severity of bronchial wall thickening, and presence of small-airway abnormalities and mosaic pattern. ⋯ Findings of this study establish a link between morphologic high-resolution CT parameters and clinical activity and emphasize the role of bronchial wall thickening in patients with bronchiectasis.
-
To evaluate spinal injection procedures for trends in volume, reimbursement, and physician specialty participation. ⋯ Spinal injection volume and reimbursement have increased substantially in the Medicare population from 1993 to 1999. During this interval, radiologist participation has decreased. Nonradiologists perform most spinal injection procedures.
-
To assess magnetic resonance (MR) imaging findings after acute lateral patellar dislocation (LPD) with emphasis on the medial patella restraints and to describe a medial patellar impaction deformity. ⋯ Injury to the medial retinaculum, MPFL, and VMO may be identified at MR imaging after acute LPD. Concave impaction deformity of the inferomedial patella is a specific sign of prior LPD.
