ExamCard description

This ExamCard is developed on Ingenia 3.0T at Release 5.4. The 32-channel Head coil is used.

In this multiparametric neuro-oncology ExamCard scan time reduction of structural sequences is achieved with Compressed SENSE (23% exam time reduction compared to SENSE acceleration when using 32ch head coil - see table below). This allows to include physiological sequences - 3D pseudo-continuous Arterial Spin Labeling (pCASL), 3D Amide Proton Transfer (APT) and Dynamic Susceptibility Contrast (DSC) - while keeping the total exam time under 30 minutes and without compromising image quality.

This is the standard brain tumor protocol at the Dent Neurologic Institute. Use of 32-channel Head coil is recommended for maximum acceleration.

The full protocol consists of:

  • Sagittal 3D T1
  • Coronal T2
  • Axial T2
  • Axial 3D FLAIR
  • Axial DWI
  • Axial SWIp 
  • Sagittal and Coronal PCA - for pCASL planning 
  • Axial 3D APT 
  • Axial 3D pCASL
  • Axial DSC perfusion
  • Sagittal contrast-enhanced 3D T1

Sagittal and coronal PCA sequences are done before APT to allow for pCASL planning while APT is running.

Early experiences with scan time reduction and image quality were presented at the ISMRM Workshop on MRI value in 2019 in Edinburgh, Scotland. A table of our findings is attached. For the full program and abstracts of the workshop see: https://www.ismrm.org/workshops/2019/MRValue/program.htm
