Introduction In magnetic resonance imaging (MRI), imaging is performed with the aid of a strong magnetic field. The magnetic flux density is up to 3 Tesla. This results in the alignment of atomic nuclei in the body along the magnetic field lines. Especially older tattoo inks contain magnetically active ingredients (especially iron), which are also … MRT and Tattoos – You have to consider that!
Which colors cause problems in MRI? The tattoo colors have changed a lot in the last decades regarding their ingredients. While 20-30 years ago, magnetic ingredients (iron carbonates, iron hydroxide, iron oxide) were still frequently used, since the 1990s, increasing attention has been paid to avoiding these ingredients. Nevertheless, the use of magnetic substances is … Which colors cause problems in MRI? | MRT and Tattoos – You have to consider that!
What is an MRI for a stroke? MRI (magnetic resonance imaging) is a diagnostic procedure that uses magnetic fields and radio waves to create an image.

It allows an exact assessment of the small intestine mucosa with regard to connective tissue strands such as The examination can also reveal malformations, fistulas, disturbances … Duration of the MRT Sellink | Realization of a MRI ́s according to Sellink
Introduction In a magnetic resonance examination (MRI), the patient is pushed into a tube fitted with magnetic coils. With the help of electricity, a magnetic field begins to build up, which then generates an image via complex calculation processes. Indication An MRI of the liver is always performed when other imaging techniques cannot provide an … Evaluation of the liver by MRI
MRI sober An MRI examination does not have to be performed on a fasting diet per se. If, for example, an examination of the intestine or stomach is to be performed, it is important to ensure that the patient is fasting. Otherwise, this is not necessarily important. In the case of a liver examination by … MRI sober | Evaluation of the liver by MRI
Duration of an MRT examination The duration varies greatly according to the organ section to be examined. In principle, however, one can say that an MRI examination usually takes longer than a CT examination or an X-ray. If, for example, a spinal column is to be examined more closely in an MRI machine, patients must … Duration of an MRT examination | Evaluation of the liver by MRI
MRI of the gall bladder An MRI examination of the bile is always carried out when abnormalities are seen in the ultrasound that cannot be reliably assigned. Even if gallstones have been seen in the gall bladder and especially in the bile duct, an MRI examination should show the exact location of the gallstone. Elevated … MRI of the gall bladder | Evaluation of the liver by MRI
