The Magnificent MRI

By a graduated 6th grader

Intro

Oh no! I think I broke a bone! LetÕs see, how about we go and get you an MRI? Yup, you definitely broke a bone. If you havenÕt figured out what this report is about yet, (which you probably have) itÕs about MRIs!! In this report, you will learn what an MRI is, the problems and dangers of MRIs, and some history of the MRI.

What it is

       What is an MRI? Well, according to some doctors at http://www.medicinenet.com, an Magnetic Resonance Imager. So basically a HUGE magnet that can image the inside of your body.

Do you ever wonder what MRI stands for? Well, in this paragraph you will find out what it stands for. According to a dictionary, MRI stands for magnetic resonance imaging. But I already knew that. I will tell you a source so that if you didnÕt believe me, you could go there. (http://www.acronymfinder.com)

What are MRIs like? If you donÕt know what an MRI is like, (just like me) you are just about to find out. According to http://grandysdaughter.blogspot.com, It makes you feel claustrophobic and hot. There is no room for your arms to move and it is annoying with a weird rhythm of knocking and beeping.

       How have MRIÕs improved? According to http://www.howstuffworks.com/mri.html, there were only a handful of MRI scanners in the entire United States. Today there are thousands. We can image in seconds what used to take hours. We now have thousands of them, but we used to only have a couple. Also, it used to take hours to get the pictures, and now it only takes seconds.

       How small is the smallest size of MRI? According to http://wiki.answers.com, there are very small scanners for imaging specific body parts are being developed. For instance, a scanner that you simply place your arm, knee or foot in is currently in use in some areas. So they have specific "mini" MRIÕs to scan separate parts of your body like head, or leg, or arm.

Problems and Dangers

       Have you ever wondered what it would feel like to get an MRI with a tattoo?  Well, according to Lissacal,  (http://answers.yahoo.com) he sais ÒI have completed nearly 5,800 studies on the MRI machine I am currently using. I have never had a patient complain about their tattoos heating up. There are very few cases of this happening, and it is usually from tattoos which were done many years ago. The ink used back then contained more metal than today's ink. Most reports of tattoos heating up are from cosmetic tattoos (eyeliner). For some reason, they contain more metal. I still have never had a patient with these tattoos complain of pain. I also have 4 tattoos and I am exposed to the magnetic field daily, and mine have never heated up. When you have a MRI, you fill out a questionaire regarding metal in your body (pacemaker, aneurysm clips in your brain, cochlear implants, etc). This is reviewed by the technologist, in order to be sure a MRI study is safe for you. I have never seen the question, "do you have any tattoos?" Although, my facility does ask if a patient has permanent make up. For those patients who do have eye tattoos, we warn them that VERY RARELY the ink can heat up. They are instructed to speak up if they feel this sensation so we can pause the study and apply ice packs to the eyes. I have never once had to stop a MRI study to apply ice packs.Ó So the answer is yes and no. He said that the old tattoos might cause it to hurt cause they have more metal. And the modern day tattoos probably donÕt. He also said that heÕs never heard any complains about peoples tattoos hurting.

History

       When was the MRI invented? According to http://wiki.answers.com, the original MRI was invented in the year of 1973. I donÕt know what month or day but you can juust look at http://wiki.answers.com and see if it is there, cause I didnÕt see it.

Conclusion

You have learned about the magnificent MRI. If you liked it, which you better have, keep learning about the MRI. Thank you!
