PURPOSE To assess magnetic resonance imaging as a diagnostic tool of neurovascular compression in a patient with abducens nerve palsy. METHODS We performed magnetic resonance imaging of the brainstem of a 46-year-old patient with left abducens nerve palsy using spoiled gradient recalled acquisition in the steady state (SPGR), which allows high-resolution(More)
PURPOSE To describe the thin-slice magnetic resonance imaging features of vascular compressive oculomotor nerve paresis. METHODS We performed thin-slice (2 mm thick) magnetic resonance imaging of the brainstem in a 74-year-old woman with right partial oculomotor nerve paresis using spoiled gradient recalled acquisition in the steady state. RESULTS(More)
PURPOSE The purpose of this study was to assess phase shift due to the inversion recovery process and the chemical shift effect in inversion recovery prepared gradient-echo magnetic resonance imaging. MATERIALS AND METHODS The signal intensities of three phantoms, composed of physiologic saline solution with Gd-DTPA, olive oil, and fat emulsion, were(More)
