ISMRM 24th Annual Meeting & Exhibition 07-13 May 2016 Singapore

Sunrise Educational Session: Interventional MRI: Technology

Skill Level: Intermediate

Organizers: Michael S. Hansen, Ph.D. & Viola Rieke, Ph.D.

Tuesday 10 May 2016

Overview
This course gives an overview of the different configurations of an interventional MRI suite, and discusses requirements of accessibility and safety during interventional or intraoperative procedures. Pulse sequence requirements, reconstruction and display for real-time MR image guidance are presented.

Target Audience
This course is aimed at both physicists and clinicians interested in interventional MRI.

Educational Objectives
Upon completion of this course, participants should be able to:

  • Identify the characteristics and special requirements of an interventional or intraoperative MRI suite; and
  • Recognize the pulse sequence requirements for real-time image guidance of various interventional procedures.

The Interventional MRI Suite

For interventional procedures, MRI-guidance has the advantage of soft-tissue visualization and no ionizing radiation exposure, compared with X-ray guidance. The features of an interventional MRI suite include specialized systems for image acquisition and display, communication, anesthesia, and hemodynamic recording. For each type of interventional procedure, MR compatible devices (e.g. needles, catheters, guidewires) need to be carefully chosen.  With careful planning and diligent staff training, a standard MRI suite may be adequately equipped to safely perform clinical interventional procedures.

Real-Time Image Guidance

MRI-guided interventions use a continuous stream of images to perform an invasive procedure on the patient inside the MRI scanner bore. Interventional MRI demands rapid image acquisition, rapid image reconstruction and rapid image processing to achieve this task. Furthermore, MR-guided interventions require simultaneous visualization of interventional devices and interactive control of imaging. Here, the real-time imaging methods used for MR-guided procedures will be described.
