Answer

The ideal contrast-enhanced breast MRI sequence has the following parameters:

  • Temporal resolution of less than 30 seconds.

  • Volumetric acquisition with at least 28 sections and no intersection gaps.

  • Isotropic spatial resolution of less than 1 mm.

  • High sensitivity with the contrast agent.

  • Perfect removal of the fat signal.

  • Capability to image both breasts entirely in one pass.

Because of current hardware limitations, no current sequence has all of these characteristics. However, novel methods for k-space filling, such as spiral 3D imaging, may allow this ideal sequence to be achieved in the near future.
