Benjamin D. 5th Grade Pond Hill School

I’ve always loved the human body, and I’ve researched it for quite a while. I also love computers and electronics, so I decided to do my S.T.E.P project on the medical imaging devices- the MRI and CAT scanners! MRI scanner CAT scanner

Quick Facts MRI stands for Magnetic Resonance Imaging An MRI machine can make “slices” of organs. The MRI scanner is the machine of choice to locate tumors. Steps for an MRI 1.Consult with doctor 2.DO NOT eat anything within ten hours of the scheduled time for scan. 3.Have scan 4.Wait for results from doctor

How it works The CAT scanner uses powerful but safe x-ray beams to show the body. It uses many x-ray beams, at many angles, many times. With the CAT scanner, we can show various tissues using different colors. Suggestions Do not wear anything metal or electronic while having a CAT scan. Consult with your doctor if you are claustrophobic.

Q: How do rocks show up on the scans? A: White Masses, because they are very dense solids. Q: How much magnetic force does the MRI scanner use? A: 180 – 270 gauss. Q: What will happen to the scanners in the future? A: Scanners will get lighter and easier to manage. Q: How do doctors know from an MRI if the patient has a tumor? A: The spot is slightly darkened and the person takes another test to make sure.
