If you have decided that an extremity MRI is right for you, it's clear that you're ready to affordably expand your facility's capabilities, reallocate your workload, and, ultimately, break through the "time ceiling". Now the question becomes: "Which extremity magnet is right for me?"
The 3 Types
To begin making your selection you must know the 3 general types of extremity MRIs that are available:
- High-field superconductive
- Low-field permanent
- Low-field permanent with limited shoulder capability
Pros for all types:
- They all have small footprints
- They will all give you good images for extremity scanning
- They will all cost less than a new standard MRI
Cons for all types:
- They only scan extremities
- You cannot image limbs that are larger than the bore (i.e. the limbs of severely obese patients)
Now that you have a general picture of extremity MRI, let's break it down further and take a look at each type on its own.
Example: ONI 1.0T Extremity MRI
These come in 1.0T and 1.5T flavors. Both are hard to get on the secondary market, but 1.5T versions are especially rare at this point. The decision on 1.0 vs 1.5 may simply come down to availability, but both approach the image quality level of standard magnets.
- The best images available for extremity magnets
- No significant drop off of image quality from your standard full size MRI
- Unlikely to be removed from insurance reimbursement lists anytime soon.
- Cannot image shoulders
- Uses cryogens (small amounts compared to standard magnets) so service costs are greater
Example: Esaote 0.2T C-Scan Extremity MRI
Not all insurers will reimburse a scan on a 0.2T magnet, but the low cost and small footprint of these magnets make it a way to free up your site's primary MRI for a higher volume of "big-ticket" studies while still serving patients that only need an arm or leg scan.
- Lowest cost
- Cannot image shoulders
- .2T is a significant drop-off in image quality from standard full-size MRI
- Some insurers will not reimburse for scanning on a .2
Low-Field Permanent with Limited Shoulder Capability
Example: Esaote 0.2T E-Scan XQ Extremity MRI
All the time and space-saving benefits of low-field permanent magnets, plus some of the shoulder scanning capabilities of standard magnets.
- Can image shoulders
- Relatively low price point
- Similar image quality drop-off to the C-Scan
- Similar insurance concerns to the C-Scan
