Pelvic MRI on 3.0T

This application tip gives tips and hints with respect to pelvic imaging on 3.0T.

 

Note that there are more Application Tips related to this topic:

 

Body MRI: dealing with typical 3.0T issues as SAR, SNR, artifacts and measures to take to overcome these artifacts.

Abdominal imaging: dealing with specific sequences and typical parameter settings.

Patient preparation

As pelvic imaging suffers from motion artifacts particularly in female pelvis, it is recommended to apply a bowel motion suppressant.

Scan methods

  • T2w-TSE is the primary method.

  The SAR limitations lead to longer TR and longer scan times.
  However, due to the very high SNR the NSA can be reduced leading to short scans times and

  excellent high resolution image quality within less than 5 minutes. 
  A small FOV with a 256 scan matrix gives the best compromise for scan time.

 

  • Single Shot sequences can easily be used providing very good image quality withing very short scan times and with a clearly reduced artifact level.

 

For post-contrast dynamic imaging use

  • either the sequence THRIVE, SPAIR, 120 slices, 2 mm x 2 mm x 1 mm overcontiguous, 21 s;
  • or the sequence THRIVE, SPAIR, 120 slices, 1 mm x 1 mm x 1 mm overcontiguous, 80 s.
