Pulse Sequences

Arms at the side

1.     BFFE Survey (3 plane)

2.     2DTOF Axial (Do NOT use a saturation band) (2mm)

3.     2DTOF Sagittal (Do NOT use a saturation band) (2mm)

Arms above the head

1.     BFFE Survey (3 plane)

2.     2DTOF Axial (Do NOT use a saturation band) (2mm)

3.     3D_512 dynamic Pre contrast Coronal

4.     3D_512 dynamic Post Contrast Coronalˆ3 sets of dynamic images

5.     Axial Single Shot TE200 (5 mm slice thickness)

6.     Axial THRIVE

Notes

1.     Images should be centered in the upper thorax in the region of the thoracic inlet at the level of the clavicle/1st rib bilaterally

2.     Use a reasonably large FOV

3.     Image both sides for Axial and Coronals; image the affected side for sagittals.

4.     Use Elliptocentric k-space filling (aka CENTRA)

5.     Fat Sat is incompatible with CENTRA

6.     Time the contrast bolus off of the aortic arch. (i.e. begin scanning when contrast reaches the arch)

7.     Use Multihance 0.15mmol/kg
