MRI machines have transformed medicine, enabling detailed, non-invasive imaging of the human body using the quantum behavior of hydrogen atoms. Unlike X-rays or ultrasounds, MRIs rely on ...

In traditional MRI scanners, a strong, uniform magnetic field forces some of the hydrogen atoms inside a patient or sample to “spin” in the same direction.

In MRI, hydrogen atoms in the body--atoms that are mostly contained in water molecules and fat--are excited using a magnetic field. The excited atoms, in turn, ...

There are a lot of hydrogen atoms in soft tissue, because soft tissue is rich in H2O, aka water. (The skin is about 64 percent H2O and the lungs are 83 percent, according to a 1945 paper in the ...

The hydrogen atoms in water have different values of T1 depending on the tissue in which they’re present. An MRI machine exploits this fact to show different tissues in different shades of grey.

New MRI method could allow for gene expression to be ... have developed a way to visualize gene expression in cells deep in the human body by using MRI signals. During an MRI, hydrogen atoms in ...

When you’re inside an MRI machine, its magnetic field temporarily realigns hydrogen atoms in your body, according to the Mayo Clinic.Radio waves make these atoms create very faint signals—and ...

The new MRI method with its special head scanner could also be used by researchers to better visualise other solid tissue ... the hydrogen atoms in myelin tissue move less freely than those in ...
