Magnetic Resonance Imaging (MRI) is the full name of magnetic resonance imaging, and stents can usually be used for MRI, but this cannot be generalized, as it depends on the material of the stent, and if it is made of magnetic metal, then it cannot be used for MRI. In general, stents are mainly coronary stents, whose materials are cobalt-chromium alloy and nickel-titanium alloy, etc., which are non-magnetic metals, so they can be examined by MRI and will not cause any effect. MRI is usually performed to help diagnose diseases such as cerebral infarction and cerebral hemorrhage. In addition, for patients who have magnetic metals in their body, they are not able to undergo MRI. This is because during the examination, the metal may shift due to the influence of a strong magnetic field from the outside, causing blood vessel rupture and other hazards, which may pose a serious threat to the safety of life. Usually, if you need to undergo an MRI after having a cardiac stent installed, you should go to the hospital in time and choose the appropriate examination method after the doctor has made a comprehensive assessment of your condition.
