ExamCard purpose

This Release 5.1.7  ExamCard is used for imaging the total spine in two stations on Ingenia 1.5T.

The ExamCard includes sagittal survey, coronal survey, sagittal T1W TSE and sagittal T2W mDIXON TSE.

ExamCard overview

Total scan time is 16:00 min.

 

One mDIXON TSE acquisition can replace two separate scans with and without fat sat, which can save time in pre- and post-contrast imaging.

 

In addition to its ability to save time, mDIXON TSE shines by consistently producing very homogeneous fat suppression allowing us now to scan larger areas with a homogeneous fatsat. In the spine, for instance, we can now do a T2 mDIXON TSE with equivalent resolution and obtain image series with and without fatsat in the same time as needed for the traditional STIR sequence. We experience flexibility in changing TE and finding the right balance between resolution and SNR.

Patient preparation

The patient is positioned supine, head first, and scanned with the dS Posterior and dS Head base coils.

Postprocessing

Fusion is included as inline postprocessing to obtain whole spine images. New series are generated in the Patient Database as T1W TSE, T2W mDIXON TSE water-only, and T2W mDIXON TSE in-phase.
