STANDARD BREAST MRI
Sequences:
Localizer
In phase sequence
T2 w fat sat
Inversion recovery sequence
T1 fat sat precontrast
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.
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
