Abstract: Objective To explore the evaluation of three-dimensional fast imaging employing steady-state acquisition(3D-FIESTA) sequence in the diagnosis of non-tumorous midbrain aqueduct stenosis.Methods 48 patients with non-tumorous midbrain aqueduct stenosis were performed by conventional SE sequence and 3D-FIESTA sequence on a 1.5T superconductive MR unit.Then the advantage on showing aqueduct of midbrain foramen was retrospectively analyzed.Results The detecting rate of midbrain aqueduct stenosis was 98% (47/48) on 3D-FIESTA sequence and 79% (38/48) on conventional SE sequence,3D-FIESTA was more advanced on showing the aqueduct of midbrain(P <0.01).Conclusion The combination of 3D-FIESTA with MPR can clearly show the midbrain aqueduct stenosis,and be a new MRI examination way of obstructive hydrocephalus.
