Pelvis with myoma with and without Compressed SENSE

Case Study

MRI of the pelvis

In this MRI examination  of the pelvis, sequences with and without Compressed SENSE are compared.  Compressed SENSE was used to reduce scan time in the 2D scans and to increase spatial resolution in the 3D PelvisVIEW scan.

MR examination

In this pelvis MRI exam of a patient with myoma, Compressed SENSE is used to accelerate individual sequences and thus the entire examination on Ingenia 1.5T.

The use of Compressed SENSE accelerates scanning times and increases spatial resolution in 3D PelvisVIEW.

Impact of Compressed SENSE

Compressed SENSE allowed for a decrease in scan time for the T2 TSE from
3:38 to 1:46 minutes. The Compressed SENSE images in this case show fewer motion
artifacts than the images from the previous protocol with SENSE.

In 3D PelvisVIEW, the Compressed SENSE images have a higher and isotropic spatial resolution with a scan time similar to the SENSE sequence. The improved spatial resolution
and better contrast in the myometrium of the uterus allowed radiologist Dr. Koyama to confidently diagnose the lesion in the uterus.
