Hello. I have had many previous spine surgeries (Hardware from L3-S1). I am now having another MRI to look at L1-3. Would a 3 Tesla MRI vs a 1.5 Tesla be better, or would it create too much artifact and blur the results? What would the standard be for a patient with hardware (rods/spacers/screws) 1.5T or 3T?

Thank you for your time.

Hello, Troy.

I have no experience with a 3T magnet. That being said, I did a little research and found this technical article:

The way I understand this article, it looks like the Radio Frequency artifacts would be less in a 1.5T than in a 3T magnet. So, I would say that you should be scanned in a 1.5T magnet.

For more information, I recommend you ask a radiologist or your ordering physician.

Hope this helps,

I am not qualified to interpret diagnostic imaging or to diagnose disease. Please consult a physician for that information. I am the photographer. I can tell you what to expect during most MRI, CT and X-ray procedures.


I now have more than 30 years experience in diagnostic imaging. My specialty is MRI. I am also very familiar with CT and the way we used to take x-rays (everything's digital now)!

I received my Bachelor of Science degree in Radiologic Technology.
