Magnetic resonance imaging (MRI) diagnosis of cancer is a new medical diagnostic imaging technology, 70 years of the 20th century with the computer, low-temperature superconducting technologies such as microelectronics and integrated development of the product. Since the 20th century, 80 years since the formal application, showing the unique advantages of deep brain tumors, brain stem tumor, spinal cord tumors, mediastinal tumors can be diagnosed.
Despite the unique role of magnetic resonance imaging, but whether MRI should be done depending on the circumstances related to medical care decisions. CT examination is currently more popular, the price is relatively low compared with MRI, CT can confirm it with the general cancer, there is no need to use magnetic resonance imaging.
Magnetic resonance imaging (MRI) of patients diagnosed with cancer when the check
Patients should be carefully checked before the memories of the body to stop bleeding without shrapnel or metal clips, metallic foreign bodies (such as eye trauma, etc.) and metal prosthesis, so as to prevent the object moving in the body, damage organs or large blood vessels. Patients with cardiac pacemaker, an absolute contraindication checks.
Magnetic resonance imaging (MRI) diagnosis of cancer, the patient access to high magnetic field, it can not be any magnetic metal objects into the MRI room, including watches, glasses, metallic accessories, BP, mobile phones, magnetic cards, coins, keys, knives and lighters, etc., do not wear with metal buttons, hooks or the zipper of clothes and belts. Do patients with head and neck examination, not to the teeth with metal hooks. Body with a metal IUD should be removed after the tests.
