Three-dimensional venography of the brain with a volumetric interpolated sequence

Radiology. 2005 Mar;234(3):901-8. doi: 10.1148/radiol.2343031956.


Informed consent was obtained from all patients before participation; study was approved by institutional review board. Three-dimensional (3D) gradient-echo magnetic resonance sequences can be optimized for rapid acquisition through asymmetric k-space sampling and interpolation of image data. A T1-weighted volumetric interpolated brain examination sequence (acquisition time, 1 minute 24 seconds) was prospectively compared qualitatively and quantitatively with magnetization-prepared rapid acquisition gradient-echo sequence (acquisition time, 6 minutes 6 seconds) for venography of cerebral venous structures in 21 female and seven male consecutive patients (mean age, 52.9 years; range, 16-81 years). Although signal- and contrast-to-noise ratios were substantially lower for volumetric interpolated sequence, difference in the subjective quality of visualization of cerebral venous structures was not significant (P >.05). Volumetric interpolated brain examination seems promising as a more time-efficient alternative for 3D imaging of cerebral venous structures.
