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