Original title: Can I have a magnetic resonance examination with a titanium clip
in my body? The titanium clip is mainly composed of a clip made of titanium
alloy and a tail part of the titanium clip, and the two parts play a main role
in the titanium clip. Because its metal part is made of titanium alloy, it is
called "titanium clip". Titanium clips can be divided into two types: one is
metal titanium clips and the other is absorbable polymer clips (surgical
hemostatic clips). These clips will remain in the body after surgery! The main
application of titanium clip is titanium alloy, which is widely used in various
fields because of its high strength, good corrosion resistance and high heat
resistance! With the popularity of magnetic resonance, more and more patients
need magnetic resonance examination! Magnetic resonance imaging (MRI) is widely
used in clinical medicine and medical research due to its advantages of
non-radiation and high resolution. Magnetic resonance examination has the
advantages of high resolution, uniform magnetic field,

imaging. At the same time more sensitive to metal, because of the high magnetic
field, metal and magnetic resonance is an absolute taboo! Metal is attracted by
a strong magnetic field and moves,

Expand the full text Because the metal titanium clip is a non-ferromagnetic
metal, and the non-ferromagnetic material does not move or only moves slightly
in the magnetic field, it does not pose a threat to the examiner. So there are
titanium clips in the body to do magnetic resonance imaging! However, the
density of pure titanium is relatively high, which will produce less artifacts
in magnetic resonance imaging! The smaller artifacts produced will not affect
the diagnosis! According to Faraday's theorem,

titanium bar, a changing magnetic field causes a current to flow in a
conductor closed within the magnetic field. Therefore, gradient magnetic field
and radio frequency pulse can induce metal materials to produce current, and
then heat, so that the local temperature rises! Studies have shown that in
routine MR examination, the effect of eddy current heat generation of metal
materials is negligible (generally below 0.15 ° C) and will not cause harm to
human body! However, some experimental studies have shown that the artifacts of
titanium alloy implants on 3. 0 T MRI images are significantly greater than
those on 1. 5 T MRI images. This is due to the fact that after the metal object
enters the main magnetic field of the MRI system, the magnetic lines of force
are highly concentrated on the object, producing an additional strong magnetic
field around the object! Therefore, when patients have titanium clips in the
body, try to choose 1.5T magnetic field for nuclear magnetic resonance
examination without affecting the diagnostic results! Avoid interference from
artifacts! References: [1] Liu Guangshun, Ren Qingyun, Meng Lingqiang, Lei
