1.5 Tesla Magnetic Resonance Imaging Scanners Compared with 3.0 Tesla Magnetic Resonance Imaging Scanners

Last updated: January 29, 2011
Product Line: Optimal Use
Result type: Report

CADTH Pilot Project

This CADTH pilot project assessed the clinical effectiveness of 1.5 Tesla magnetic resonance imaging (MRI) scanners and 3.0 Tesla MRI scanners.

As part of the pilot project, CADTH:

  • appraised the comparative clinical benefits, limitations, and safety considerations of 1.5 Tesla MRI scanners and 3.0 Tesla MRI scanners; and
  • developed expert guidance to help inform decisions on the purchase and use of 1.5 T and 3.0 T MRI scanners.

Key Message

For most medical conditions, use of 3.0 T MRI or 1.5 T MRI leads to similar health outcomes, including safety.

Based on expert opinion, 3.0 T MRI may offer advantages for advanced clinical neurosciences and some cardiovascular applications.

Reports

In keeping pace with an evolving environment and providing timely information to health care systems in Canada, the Canadian Agency for Drugs and Technologies in Health (CADTH) has undertaken a pilot project to appraise the comparative clinical benefits, limitations, and safety considerations of 1.5 Tesla (T) Magnetic Resonance Imaging (MRI) scanners and 3.0 T MRI scanners.

To help inform decisions on the purchasing and use of 1.5 T MRI and 3.0 T MRI scanners, the CADTH MRI Expert Advisory Panel produced a guidance report after considering the following:

  • CADTH’s completed research.
  • Manufacturer information.
  • Clinical and technical expertise.
  • Public values and preferences.
