STANDARD BREAST MRI
Sequences:
1.Localizer
2.In phase sequence
3.T2 w fat sat
4.Inversion recovery sequence
5.T1 fat sat precontrast
6.T1 fat sat post contrast x 3
■ Inject contrast. Scan first pass immediately (no delay)
■ Scan 2nd pass immediately when 1st pass finishes.
■ Scan 3rd pass immediately when 2nd pass finishes.
■ *Send precontrast, post contrast pass 1, pass 2, and pass 3 each separately to PACS (ie not stacked or interleaved, but each as their own independent sequence in PACS).
■ *Send SUBTRACTED post contrast pass 1, 2, and 3 each separately to PACS (ie there should be 3 individual separate subtracted sequences in PACS).
■ *Send sagittal reconstruction of post con pass 2.
■ *Send sagittal reconstruction of SUBTRACTED post con pass 2.
7.MIP series
■ Axial MIP of the subtracted pass 1, subtracted pass 2, and subtracted pass 3 (total of 3 MIP images). These need to be STACKED, so that they are in PACS as 1 series - 1st image is sub pass 1 MIP, 2nd image is sub pass 2 MIP, 3rd image is sub pass 3 MIP.
Specific parameters for the T1 fat sat precon and the T1 fat sat post contrast images are as follows:
■ 3D acquisition
■ 1 mm slices
■ Contiguous with no gap
■ FOV: 300 mm
■ Matrix: 300 x 300
■ Voxel size: 1 x 1 x 1mm
