Patient preparation

The patient was positioned head first and arms above the head. This is done to avoid compensation for them in the scan which can adversely affect the scan time.

The SENSE XL Torso coil was used.

Postprocessing

A dynamic movie was created with VolumeView: large slab MIP angle through left renal vein with relevant dynamics included in propagation.
