Can I have a magnetic resonance examination if I have a titanium clip in my body?
Original title Can I have a magnetic resonance Titanium 6Al4V wire 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 titanium filler rod polymer clips (surgical hemostatic clips) These clips will remain in the body after surgery! bra tape measure 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 fast scanning speed relatively low noise and multi-directional imaging At the same time more sensitive to metal because of the high magnetic field metal and magnetic resonance is an absolute taboo! titanium bar gr5 Metal is attracted by a strong magnetic field and moves which may have serious consequences and even endanger life 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 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 nickel titanium wire 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 titanium plate gr7 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 15T magnetic field for nuclear magnetic resonance examination without affecting the diagnostic results! Avoid interference from artifacts!
