MRI Burn Prevention

[@BodiaH]

hey, just today got intense heating of an area on my knee during MRI scan. NOBODY informed me that I had to watch out for burning sensation or that may be dangerous. for 15 min it was normal. Then I felt a burning sensation, I was surprised, then it went away briefly then came back stronger. After the third time it felt tile my ligament is going to explode and I squeezed the bal. Nurse came in and instead of explaining anthing she simply asked me "do you want to stop the procedure?". I'm like "I have no idea, is it safe to proceed while I'm feeling burning and like my tissue is going to explode? Can it cause me any harm?" She said, no o harm can occur. So we resumed. I felt no burning after it was resumed, but I feel like my knee suffered permament damage and it feels injured. Heating up an injured ligament can cause tear of tissues. Fucking unprofessional ignorant bastards injuring patients during a check up. (I'm based in Ukraine. MRI was done in "EUROCLINIC" in LVIV city).

Hi I work with these magnets. This is the reason why there is safety checking, we ask patients wether they have metal inside their body and outside their body i.e brain shunt, heart pacemaker etc. This things can still be scanned with limitations on the power that we use, it is very important to tell the technologist your health and history of surgeries that involves metals and accidents such as metal shrapnels that went inside their skin. If there is a case that the patient had an unknown metal shrapnels accident specially in the eyes, we tend to abandon the scan and request for an xray. This is why MRI safety questionnaire is in place. Now a days most surgeries that involve metals are MRI compatible so most of MRI technologist knows how to deal with patient that has it. With regards to your query, as long as there is no metal(specially ferrous magnetic i.e iron based) attached on your knee you should be fine. With knee scan most of the patient would comment that they experience a kind of pulling sensation around the area of the scan, this is because the water molecule aligns with the iso center of the machine we also use specific camera (MRI coil) on the part that is being scanned and this entails safety as well. I hope I am able to answer your worry.

@@marifeltiamsic9471 hello. It's not a worry. It's a statement of what happened. My leg was feeling ill for 3 days at least after that. It seems I didn't suffer too much damage (or I'm failing to detect the damage, since it's under the skin and I'm not stupid enough to force load on my injured ligament just to prove a point). Good thing I signaled the MRI stuff to turn it off when I did, other vice I would have suffered that burn 100%. The only thing I found out from your comment is that if you limit the power it's possible to scan with non-ferrous metals present. But failed to highlight that even with no metals present the patient can still suffer a burn if too much power is used (which I'm sure is what happened to me). It's all about money, more power = faster scan, faster can put another patient and take their money.
