More important for diagnosing focal processes in the liver by examination is the liver MRI. The basis of MRI is the use of magnetic properties of protons distributed in all parts of the body.
Visualization with MRI depends on the rearrangement of the nuclei of hydrogen atoms (protons charged positively) in tissues under the action of a short electromagnetic pulse.
The most common indication for MRI of kidneys is the diagnosis and staging of tumors. Nevertheless, CT for the same purpose is prescribed much more often.
Diffusion is the main physical process that occurs during metabolic reactions of the cell. The first diffusion-weighted MP image was built in 1985. In clinical practice, diffusion MRI came with the MRI scanners of the generation III. To obtain diffusion-weighted tomograms, echoplane pulse sequences "spin echo" EPI with two diffusion gradients of the same amplitude and duration are used.
