Shorter scan time in brain with Compressed SENSE

Case Study
Sartoretti, Sabine, M.D. Institute of Radiology, Kantonsspital Winterthur • Switzerland

As soon as the Compressed SENSE technology became available to the MRI team at Kantonsspital Winterthur (Switzerland), the site started applying the acceleration possibilities for their MRI scans of the brain, spine and joints as well as pelvis and abdomen.

 

Using Compressed SENSE appeared a simple yet powerful way to accelerate MRI scanning for different contrast types and sequences, in 2D as well as 3D.

MR examination

FLAIR in the brain with and without using Compressed SENSE was performed on Ingenia 1.5T.

 

In this example, the sequence with Compressed SENSE factor 8.2 has a 28% shorter scan time with the same spatial resolution.

Impact of Compressed SENSE at Kantonsspital Winterthur

The significantly reduced scan times in different anatomies convinced the team to plan for adjusting all their ExamCards, with the objective to shorten patient timeslots and then actually plan for increasing their number of MRI patients per day.
