VIBRANT with Flex Imaging Option

VIBRANT (Volume Imaging for BReast AssessmeNT) with Flex Imaging Option is a single slab 3D, dual echo, Fast SPGR application that acquires out-of-phase and in-phase echoes used to generate fat and water images using a two-point Dixon technique. The VIBRANT with Flex is compatible with Breast coils and can be used for either bilateral or unilateral breast imaging.

To shorten scan time, VIBRANT with Flex uses a partial fourier acquisition technique and ARC. It also uses a high receive bandwidth to minimize chemical shift effects and to acquire the first out-of-phase and in-phase echoes within the same TR.

PURE and other image filter considerations

Keep the following important points in mind when using PURE or other image filter options with scans that are post processed or displayed in a viewer.

  • The PURE feature changes the pixel intensity in the image to provide a more uniform image. This may lead to altered results when CADstream is used in conjunction with PURE for processing MR images. A modification to the CADstream difference threshold may be required. It is recommended to either disable PURE for dynamic studies or applying the PURE feature uniformly across all the dynamic series.
  • The output of post processing can be modified with any change to the protocol. For optimal image quality, keep consistency with protocols and use the same type of filter or apply PURE for both pre and post contrast imaging.
  • Refer to the CADstream operator manual or contact a Merge CAD representative regarding any change to your dynamic breast protocol and the use of PURE or other image filtering techniques.
