Magnetic resonance imaging is a new medical imaging technology by using nuclear magnetic resonance principle for brain, thyroid, liver, gall bladder, spleen, kidney, pancreas, adrenal gland, uterus, ovary, prostate and other solid organs as well as heart and great vessel has excellent diagnostic features. Compared with other means of supplementary examinations, parameters of nuclear magnetic resonance imaging, scanning speed, organizational advantages such as higher resolution and sharper images, can help doctors to "see" difficult to detect early lesions, has now become cancer, heart disease and cerebrovascular disease, early screening tool.
It is understood that because the metal will increase the external magnetic field interference, the patient prior to the MRI scan, you must remove metals from the body. Not allowed to wear magnetic items, such as watches, metal necklace, metal buttons, metal buttons, metal loop of magnetic resonance imaging.
Moreover, wear a pacemaker, ParaMagnetic metal implants in the body, such as metal clips, brackets, plates and screws, and magnetic resonance imaging is not possible. Upper abdomen (such as the liver, pancreas, kidney, adrenal, etc) MRI must be fasting, but to drink adequate amount of water before checking, to clarify the boundaries of stomach and liver, spleen.
