Body MRI on 3.0T

Application Tip
Jones, Alun Philips Healthcare Philips Global
van den Heuvel, Martina Philips Healthcare Philips Global

Body MRI on 3.0T is a new and exciting challenge as high resolution can be obtained in short scan times offering excellent image quality. However, scanning on 3.0T is different to scanning on 1.5T. There are several factors to be aware of. This application tip describes these factors and also the measures to take in order to cope with them.


Note that there are more Application Tips related to this topic, all of them dealing with specific sequences and typical parameter settings:

Typical issues on 3.0T

Specific Absorption Rate (SAR) is four times higher than on 1.5T. This can lead to SAR limitations.


Signal-to-Noise Ratio (SNR) on 3.0T is two times higher than on 1.5T. Possible benefits are higher resolution (in-plane and thinner slices) and/or shorter scan times.


Artifact level can be higher on higher field strengths.

Coil choice

For body imaging on 3.0T, use the

  • SENSE Torso coil
  • SENSE Cardiac coil


For pelvic applications, the SENSE Flex-M and SENSE Flex-L coils can also be used.

General tips and hints

SAR reduction

If necessary, reduce the SAR by:

  • Using SENSE.
  • Reducing the refocussing flip angle
  • Lowering the B1 amplitude
  • Reducing the TSE train length (TSE factor)
  • Increasing the TR
  • Reducing the number of slices

Reducing artifacts

  • Be aware of the fold-over direction.


  • Use bowel motion reduction drugs if necessary (particularly in female pelvis).


  • Unless imaging the bladder, ask patients to empty the bladder prior to scanning.


  • Randomized TSE can be used.


  • Use 'body tuned' SENSE / CLEAR.

   'Body Tuned' SENSE / CLEAR is an imaging parameter on 3.0T systems which         

   compensates for field inhomogeneities in the images.


   Body tuned SENSE / CLEAR:

   This parameter is especially useful in TSE- and bTFE-scans providing much more homogeneous

   signal across the whole area.
