For one reason or another, we all sometimes have to undergo some diagnostic tests. Women during pregnancy are no exception, because they have to monitor not only their health, but also the development of the future child.
MRI of the mammary glands or magnetic resonance imaging is a study that significantly helps to establish a diagnosis of the disease and carry out its treatment.
A more significant method of examination for diagnosing focal processes in the liver is MRI of the liver. MRI is based on the use of magnetic properties of protons distributed in all parts of the body.
MRI imaging relies on the rearrangement of hydrogen atom nuclei (positively charged protons) in tissues under the influence of a short electromagnetic pulse.
The most common indication for performing MRI of the kidneys is diagnostics and staging of neoplasms. However, CT is prescribed for the same purpose much more often.
Diffusion is the main physical process occurring during metabolic reactions of the cell. The first diffusion-weighted MR image was constructed in 1985. Diffusion MRI came into clinical practice together with MRI scanners of the third generation. To obtain diffusion-weighted tomograms, echoplanar pulse sequences "spin echo" EPI with two diffusion gradients of the same amplitude and duration are used.
