3D MR cisternography to identify distal dural rings: comparison of 3D-CISS and 3D-SPACE sequences.
PURPOSE The distal dural ring (DDR) is an anatomical landmark used to distinguish intra- and extradural aneurysms. We investigated identification of the DDR using 2 three-dimensional (3D) magnetic resonance (MR) cisternography sequences--3D constructive interference in steady state (CISS) and 3D sampling perfection with application optimized contrasts using different flip angle evolutions (SPAC...
متن کاملIdentification of the distal dural ring with use of fusion images with 3D-MR cisternography and MR angiography: application to paraclinoid aneurysms.
BACKGROUND AND PURPOSE The distal dural ring (DDR) represents the anatomic border between the extradural and intradural internal carotid arteries (ICAs). The purpose of this study was to examine whether 3D-MR cisternography and MR angiography (MRA) fusion images can identify the boundary between the CSF and the cavernous sinus, which might represent the DDR. MATERIALS AND METHODS Thirty-six c...
متن کاملHigh-resolution MR cisternography of the cerebellopontine angle: 2D versus 3D fast spin-echo sequences.
BACKGROUND AND PURPOSE The clinical usefulness of MR cisternography of the cerebellopontine angle, applying 2D or 3D fast spin-echo sequences, has been reported recently. Our purpose was to investigate the cause of signal loss in CSF in the prepontine or cerebellopontine angle cistern on 2D FSE MR images and to compare the cisternographic effects of 2D and 3D FSE sequences. METHODS Preliminar...
متن کاملComparison of FSE T2W and 3D FIESTA sequences in the evaluation of posterior fossa cranial nerves with MR cisternography.
PURPOSE The aim of this study was to compare 3D fast imaging with steady state acquisition (3D FIESTA) to fast spin echo T2-weighted (FSE T2W) MRI sequences in the imaging of cisternal parts of cranial nerves V-XII. MATERIALS AND METHODS We retrospectively evaluated the temporal MRI sequences of 50 patients (F:M ratio, 27:23; mean age, 44.5 +/- 15.9 years) who were admitted to our hospital wi...
متن کاملIdentification and anatomic description of the anterior choroidal artery by use of 3D-TOF source and 3D-CISS MR imaging.
BACKGROUND AND PURPOSE The importance of the anterior choroidal artery (AChA) is related to its supply of crucial anatomic structures, such as the internal capsule. Angiographically, the AChA can be detected in 71% to 98% of patients, but as yet, its visibility on MR images has not been evaluated. Our goal was to assess the sensitivity of MR imaging in the identification of the AChA and its ana...
