Magnetic resonance imaging in Duane's retraction syndrome.
PURPOSE The aim of this study was to visualize the subarachnoid portion of the nervus abducens by magnetic resonance imaging and to analyze whether aplasia of the nervus abducens is an etiologic factor in Duane's retraction syndrome. METHODS We performed thin-sectioned magnetic resonance imaging across the brainstem level in 8 cases (11 eyes) that were clinically diagnosed as Duane's retracti...
متن کاملmagnetic resonance imaging (mri)
basic physical principles of nuclear magnetic resonance imaging (n.m.r.i), a nonionizing medical imaging technique, are described. principles of nmri with other conventional imaging methods, ie, isotope scanning, ultrasonography and radiography have been compared. t1 and t2 and spin density (s.d.) factors and different image construction techniques based on their different combinations is discu...
متن کاملDuane retraction syndrome: MRI features in two cases.
PURPOSE Neuroimaging findings in Duane's retraction syndrome (DRS), through magnetic resonance imaging (MRI), suggest that aplasia of the abducens nerve (VI) can be responsible for several forms of DRS. METHODS Brain MRI was performed in two children of 2.5 and 7 years of age with left sided DRS type II and right sided DRS type I, respectively. 3D T2 weighted images through the brainstem were...
