ExamCard purpose

This ExamCard was created on Ingenia 3.0T with release 5.1.7.

 

One of the benefits of using mDIXON TSE in orthopedic imaging is that different image contrasts can be reconstructed from one scan. Therewith, the duration of the examination can be reduced.

 

In this T1W mDIXON TSE scan used for the visualization of vertebral fractures in the lumbar spine, two different image types are reconstructed:

  1. In-phase images; and
  2. Water images.

 

With that, the necessary imaging contrasts are achieved, within one scan, where the

  1. in-phase images help to visualize fracture lines and the homogenization of the bone marrow.
  2. water images provide homogenous fat saturation over the complete lumbar spine and information on the edematous changes into vertebral body, soft tissue and posterior elements.

Patient preparation and positioning

For patient comfort, we position the patient feet first on the tabletop with the integrated Posterior coil. Place a pillow under the patient's head.

Provide the patient with the necessary hearing protection and nurse call.

Tips

1. Scan duration can be reduced by reasonably increasing the acceleration factor SENSE.

 

2. Partial fat saturation can be set to get a personalized contrast and saturation from the mDIXON TSE acquisition. This is achieved by post-processing the mDIXON TSE scan in the ImageAlgebra package where the algorithm 'Addition: (A+B)' is used; A are the water images and B are the in phase images. The degree of fat saturation can be defined interactively by the slider in the ImageAlgebra package. A new images series can be generated and the SmartLine post-processing step can be added to the ExamCard for future reuse. In this ExamCard contribution the SmartLine post-processing step is already added.
