Doing nuclear magnetic *** vibration can not bring gold bracelet. Metallic items will seriously affect the results of the NMR *** vibration, producing artifacts and interference signals, affecting the diagnosis. Therefore, you can't wear a gold bracelet when doing NMR*** vibration.
Can you wear a gold bracelet when doing NMR*** vibration
It is absolutely not possible to wear a pure gold bracelet when doing NMR*** vibration.
Not only pure gold bracelets, but also other gold and silver jewelry or wear some metal items, must be completely removed before the nuclear magnetic *** vibration examination. And before the examination, the doctor will ask the patient in detail whether there are metal implants in the body, such as pacemakers and so on. This is to ensure the safety of the patient and the quality of the images on the one hand.
On the other hand, it is also to avoid adverse effects on the machine. Metal objects can not only interfere with the uniformity and stability of the magnetic field, but also lead to a variety of artifacts affecting the diagnostic results in the process of examination, and there are some metal objects in the process of examination, but also easy to be adsorbed to the machine, causing some damage to the machine.
What are the precautions before doing nuclear magnetic **** vibration
Nuclear magnetic **** vibration (MRI) is a conventional imaging method, mostly used in the diagnosis of parenchymal organs and cardiac and vascular diseases, which has a relatively small impact on human health, but nuclear magnetic **** vibration examination needs to pay attention to a number of issues, to prevent it from affecting the results of the examination or the impact on the examinee. The examination of the subject.
1, contraindications: including the installation of pacemakers, with or suspected of metal foreign body in the eye, ear disease patients, aneurysms, silver clip ligation, metal foreign body in the body, life-threatening critical patients, claustrophobic patients and pregnant women less than 3 months pregnant, because the metal by the attraction of a strong magnetic field will produce movement, which may endanger the life of the eye, ear disease patients and claustrophobic patients, pregnant women, because the metal by a strong magnetic field will produce movement, may endanger the life of the eye, ear diseases Patients and claustrophobic patients, pregnant women may not tolerate this examination;
2, remove metal foreign objects: such as keys, magnetic cards, watches, dentures, contraceptive rings, and metal objects with iron buckle belts, guardianship instruments, resuscitation equipment, etc., will have a certain impact on the nuclear magnetic **** vibration examination, affecting the imaging, unfavorable foci of the display, and may even damage the machine;
3, Avoid make-up, nail: some cosmetics, nail polish contains metal components, in order to avoid abnormal test results, it is generally not recommended to make-up and nail;
4, lifting the medical equipment: lifting the necessary medical equipment under the guidance of the doctor, need to pay attention to the wheelchair, beds and other items with metal can not be brought into the examination room to avoid serious accidents;
5, the other: if it is the examination of the abdomen. Do NMR *** vibration will need to fasting, generally need to maintain a fasting 4-6 hours, in order to ensure the accuracy of the results of the examination; do NMR *** vibration examination, there can be a relatively large noise, in order to prevent damage to the hearing, you can bring earplugs, to reduce the impact of the noise, to protect the health of the ear.
In addition, the MRI will not harm people without contraindications, so there is no need to be nervous and worried, and try to keep the mood comfortable and relaxed.
Doing nuclear **** vibration on the body has an impact
Doing nuclear **** vibration on the human body is not very damaging, do nuclear **** vibration without ionizing radiation, the human body does not have radioactive damage. Nuclear magnetic **** vibration imaging is currently used in clinical a relatively new diagnostic imaging technology, can provide the traditional X-ray and CT can not provide information, is the diagnosis of intracranial and spinal cord lesions is one of the most important means of examination, is now in China has been widely used.
Compared with CT, nuclear magnetic **** vibration can provide multi-directional and multi-layer anatomical information, image clarity is high, there is no ionizing radiation, no obvious damage to the human body. It can not appear cranial artifacts, without the need for contrast media can clearly show the coronal, sagittal and transverse axis of the three images.
