Difference between nmr and mri
WebAn MRI machine generates a strong magnetic field in your body. The MRI then sends signals to a computer that makes a series of images. Each image will show a thin slice of your body. The computer compiles these slices into a 3-D picture. Before some MRIs, the doctor will inject contrast dye into a vein. WebMRI is an application of NMR (nuclear magnetic resonance), an analytical tool of chemists found in laboratories worldwide. Together, NMR and MRI revolutionized the practice of chemistry and medicine by providing fast, …
