Doctors examine the contrasts on an MRI scan. Ron Levine/The Image Bank/Getty Images The MRI scanner can pick out a very small point inside the patient's body and ask it, essentially, "What type of tissue are you?" The system goes through the patient's body point by point, building...

New MRIs do not require you to lie within a tube. Rather, patients having an MRI of the knee, ankle, foot, elbow, or wrist, can simply place that body part within the MRI machine. This type of machine does not work for MRI of the shoulders, spine, hips, or pelvis. ...
MRI uses a totally different mechanism to generate an image. MRI images are made using hydrogen atoms in your body and magnets. Yes, super strong magnets. Hydrogen is present in water, fat, protein, and most of the "soft tissue" structures of the body. The doughnut of an MRI does not ...
Without going into too much detail, the MRI scanner does this by triggering the protons in the tissues to produce a signal that is measured by receivers in the MRI machine and transformed into an image. Since different tissues have different density of protons, the signal can vary in ...

Your doctor might use an MRI to plan surgery or to find out for sure if a growth is cancer or not. Doctors sometimes use PET scans as well. In some cases, they can show more clearly how treatment affects a tumor. What Blood Tests Check For ...
In an unmagnetized ferromagnetic material, each domain's north pole points in a random direction. Magnetic domains that are oriented in opposite directions cancel one another out, so the material does not produce a net magnetic field. In magnets, on the other hand, most or all the magnetic ...
