Both 2DFT and 3DFT acquisitions are used in breast imaging. Typically, most non-contrast pulse sequences, such as preliminary T1 and T2-weighted scans are acquired in 2D mode, while pre- and post-contrast T1-weighted scans are acquired in 3D mode. Some sites still use 2D mode for all imaging, including CE scans. This is typically done because of the desire to obtain CE scans quickly and scanner limitations for 3D acquisitions, or under the mistaken impression that 2D acquisitions offer a SNR advantage over 3D acquisitions. We turn next to a list of prerequisites for high quality CE-BMRI.
