Before taking magnetic resonance imaging, the patient needs to provide the doctor with full information about their health status as well as the devices being implanted on the person (aneurysm clips, stents, pacemakers, IUDs) pregnancy...) to ensure a safe scanning process.

Metallic materials containing iron ions (iron, steel) placed in the environment of the magnetic resonance machine will move position. Therefore, when taking magnetic resonance imaging, metal implants in the body such as aneurysm clips, stents, pacemakers, bone fusion instruments will move and may cause damage to surrounding tissues.
In addition, metal implanted materials in the body can heat up significantly during magnetic resonance imaging and thus can also cause injury to the patient. Implants can cause signal loss and affect image quality.
Therefore, it is very important to inform the MRI technician about any implants in the patient's body before entering the MRI room.

Intrauterine contraceptive devices (IUDs) are manufactured with inert materials such as stainless steel, plastic,... with the addition of copper or the hormone progestin. There are many types of IUDs used in the world:
+ IUDs containing copper are made from a plastic body with copper rings or copper wire is the most common type today in Vietnam. There are different shapes and different copper content (TCu 380A, Multiload 375, TCu 200, ...)
+ IUD containing progestin: in Vietnam there is a Mirena ring consisting of a T-shaped polyethylene body containing 52 mg of levonogestrel.
+ Metal IUD: using stainless steel can be attached with copper wire: this type is now rarely used in Vietnam as well as in the world. However, in some parts of the world this type of IUD is still used, such as China. This type of ring has mostly been discontinued since 2000 but some elderly people in China are still wearing this IUD.

For plastic IUDs combined with copper wire or hormones: the current common IUDs in Vietnam will be safe during magnetic resonance imaging. However, for IUDs using stainless steel, there will be motion effects, heat will not be safe for the patient, so an alternative diagnostic method such as ultrasound or pelvic CT scan should be used. -gynecological.
