ISMRM Workshop on
MR Safety
Ensuring Safety from First Principles to Best Practices
University Medical Centre Utrecht, Utrecht, The Netherlands

Parallel Session 1

This session is FULL.
Spaces are still available for Parallel Session 2.

Day 2 – Saturday, 21 September 2019
Session 7: Parallel Sessions
Parallel Session 1: Hands-On MRI Safety in Clinical Practice – 2.5 CME Available
Moderators: T.B.A.

This session consists of one lecture and 3 different demos on different MR-scanners. With this hands-on session, we aim provide practical education especially to technologists/radiographers to manage the increasing complexity of MR Safety in clinic. In this session, the group will be split in 4 (or 8 depending upon the interest) subgroups and rotated over the demos and lecture. The demos and lecture will be 40 minutes with a 30-minute break in between. You can register for this session in the registration process without any additional fee.


40 Minutes Lecture on MRI Safety Workflow

Safe scanning of patients in MRI clinic requires dedicated expertise and infrastructure. Under normal MRI scanning conditions numerous MRI safety concerns (ferromagnetic objects, usage of contrast agents) already apply. In the case of patients carrying medical devices or implants, enforcing MRI safety requires additional workflow. This includes thorough patient screening procedures, obtaining information on implants to assess where the devices are safe, conditional or even unsafe. In the case of a conditional label, the interpretation and implementation of a label becomes essential. RF heating is another increasing MR safety issue that we also hope to be able to pay attention to and discuss.

In this lecture, three lecturers with practical experience from the MR safety field will lead a discussion to share experiences on how to create an improved workflow for a modern MRI clinic.

Maureen N. Hood, Ph.D., RN, R.T. (MR) FSMRT, FAHA
Vera K. Kimbrell, BS, R.T.(R)(MR), FSMRT
Titti Owman, R.N.(R)(CT)(MR)FSMRT

The specific learning objectives are:

  • Identify the roles and responsibilities of the various specialists an MRI safety infrastructure;
  • List procedures for patient screening;
  • Recall information on implants and medical devices;
  • Interpret and implement conditional labels; and
  • Describe steps to implement routines to avoid RF burns.
40 Minutes Scanning Patients with Active Implants: Live Demo at 1.5T MR Scanner

In recent years, the number of pacemakers / ICD patients for MRI has increased significantly, causing MRI safety problems and (logistic) challenges. One of the challenges is that two different departments (Cardiology and Radiology) have to work closely together in order to carry out a proper / thorough investigation to find out if it’s safe for the patient to undergo an MRI. Another challenge comes up when the active implants or leads are not MR-conditional: it should be reconsidered if the diagnostic value is more important than the risk if the patient with the active implant is exposed to the electromagnetic field. In this hands-on session, we will discuss and demonstrate which safety concerns need to be observed before and during an MRI procedure with a CIED.

Niels Jongejan, Ph.D., Rens Kruisbrink, M.Sc. & Gerrit Melis

The specific learning objectives are:

  • Identify additional safety aspects required for MRI in combination with CIED implants;
  • Indicate adjustment of parameters such as SAR, gradient slew rate;
  • Use specific accessories, like a T/R coil; and
  • Practice an optimal emergency procedure during an MRI-examination.
15:30-16:00 Break
40 Minutes Setting Up Patients in an MR Room: Live Demo at 1.5T MR Scanner

When a patient, a device or an object enters the MRI room, electromagnetic interactions occur with the MRI system. These interactions can lead to severe or even fatal events if correct screening procedures are not correctly performed before entering the MRI room. In this hand-on session, the participants will learn how to perform an MRI screening procedure, how to correctly position a patient inside MRI systems, and how to perform a calamity procedure to safely extract a patient from a MRI system when life support is needed.

Teun Coolen & Esther Verdonk

Particular attention will be paid to the following aspects:

  • The introduction of metallic objects/devices in the MR-room;
  • Screening patients with loose metal attributes and implants;
  • Correct positioning of patients on the MRI table;
  • Hearing protection from the MRI acoustic noise;
  • Monitoring of patients during MRI exams; and
  • Performing a calamity procedure for non-responding patients and in case of quench.
40 Minutes MRI Safety of MRI-Guided Radiation Therapy: Live Demo at 1.5T MRI-Linac

MRI in radiation oncology is a growing field, and many departments are currently introducing or extending the use of it. MR systems have been intensively modified to provide added value during the radiation therapy processes: RT dedicated MR-scanner (pre-treatment MR-simulator), MR- brachytherapy-intervention and MR-Linac. This means that the MRI safety aspect, in combination with radiotherapeutic setup, plays a role. Furthermore, staff from a radiation oncology department needs to be trained to create a safe environment for patients and colleagues. In this hands-on session, we discuss and demonstrate which safety concerns have to be taken into account during an MR-guided radiotherapeutic process. This session will be held on a MR-Linac "Unity."

Roel Bouwmans & Tuan Nguyen

The specific learning objectives are:

  • Predict which additional safety concerns are needed for MRI combined with radiation oncology;
  • Safely set up the patient on a radiotherapeutic MR system;
  • Safely use RT-therapeutic-specific accessories during a radiotherapeutic process combined with MRI (i.e. table top, fixation mask, breast board, table extension, and base plate); and
  • Practice an optimal calamity procedure during an MRI examination/treatment in combination with radiotherapy.
