ExamCard purpose

St. Joseph's Hospital and Medical Center has developed fast, targeted ExamCards to support the fast, confident decisions that need to be made in their Neuro Emergency Department (ED).

 

SJHMC uses mDIXON TSE extensively in spine imaging in the Emergency Department. It it's particularly nice in that it is very robust with regards to susceptibility type of problems that would come up with traditional spectral fat-saturation images; this is a great advantage of the mDIXON technique.

 

This ExamCard is created for use in the ED on an Ingenia 1.5T with Release 5.1.9 for patients with:

  • back pain
  • compression fracture (no hx malig/mets)
  • degenerative disease 
  • disc herniation
  • radiculopathy
  • sciatica
  • spondylolisthesis
  • stenosis
  • trauma

ExamCard overview

Total ExamCard scan time is 11:15 minutes.

 

The ExamCard includes SmartLine postprocessing steps for the T2W mDIXON scan.

The SmartLine steps are collapsed in the ExamCard overview.

 

In this patient a T1W coronal scan was added to visualize the location and extent of a sacral cyst in a third orientation.

Patient preparation

Position the patient head first, supine on the patient support. Place the head of the patient on the dS Base. Provide the patient with the knee support, hearing protection and the nurse call.

Postprocessing / analysis

SmartLine postprocessing steps, ImageAlgebra, have been added to the T2W_mDIXON_TSE scan to reconstruct a seperate image series of the fat images and of the water images. This enables easier viewing of the data on peripheral workstations and PACS systems.

The SmartLine steps start automatically without user interaction after the reconstruction of the original image series.
