What are the issues that patients need to pay attention to when doing MRI?

MRI, also known as MRI, has become a common way for people to go to the hospital to check their bodies. The most widely used examination for MRI is the examination of the central nervous system of the human body, such as checking whether there is damage to people's head, cervical spine, thoracic spine, lumbar spine and other conditions, and the examination effect on the brain and spinal cord is relatively strong. In addition, MRI can also examine the abdominal organs, such as the liver, gallbladder, pancreas, spleen, kidneys, etc.

Although the MRI examination is very accurate, it also has shortcomings, and some patients are not suitable for this examination method, so I will briefly introduce the precautions for patients when doing MRI.

First of all, MRI has a relatively large suction force on metal objects, so patients should remove metal accessories such as earrings, watches, glasses, etc. before performing this examination. Some patients may have pacemakers, stents, steel plates, etc. in their bodies due to certain surgeries, and such patients are not suitable for MRI examinations. The second aspect is that the patient must maintain a good mental state, not be nervous, and relax his mind, so as to better cooperate with the examination.

Because MRI is in a large machine, the magnetic field is strong and loud sounds, so if the patient is intolerant of this sound or feels afraid of this space (also known as confined space phobia), it will not be able to cooperate well with the examination. <>

The third aspect is that when women have an MRI examination, if they are planning to get pregnant or are already pregnant, they must tell their attending doctor and staff that MRI will have a certain adverse effect on the woman's body, resulting in difficulty in conceiving in a short period of time, and will cause harm to the baby. Another point I think is that before the examination, the body should be relaxed, do not exercise vigorously, or keep the body quiet during the examination, and do not turn back and forth too much, so as not to affect the examination effect.

Patients are not allowed to carry metal objects with them during MRI. This is very important、Mobile phones, metal items, and jewelry can not be brought。

The following issues need to be paid attention to in the MRI examination: 1. An appointment is required, because the MRI time is relatively long, so the waiting time is also relatively long, at this time, you need to make an appointment, and you can check on time according to the appointment time; 2. There can be no metal objects on the body during the MRI examination, and cotton clothes can be worn on the day, and there can be no metal buckles and zippers on the body, and if there are necklaces, mobile phones, and watches on the body, they must be removed.

When the patient is doing MRI, there must be no metal substances on the body, which will produce strong suction and cause great harm to the body; After that, when resonating, you must not open your eyes, because the strong radiation will make your eyes uncomfortable.

Pay attention to your physical condition, cooperate with the doctor for examination, don't have too much pressure, try to relax your mind, and follow a fixed posture for testing.

The eyes are swollen, the head is also rising, sometimes there is traction pain, it feels like the scalp is rising, and then I look at the computer for a while and look in the mirror and find that the pupils are a little big, and the throat is also a little uncomfortable, and there is an obvious symptom that the pupils are small only after lying on the table with my head down and taking a bath, but my intraocular pressure, fundus, CT film and other examinations are normal, I called the doctor to check the details, he said it is not necessary. Later, I met a more careful doctor and told me to do an MRI this Sunday.

I think we need to pay attention to the physical problems, the psychological problems, the quality problems, the moral problems, and the dietary problems.

When the patient is doing an MRI, they can't bring in metal appliances because it will affect the machine.

When patients have an MRI, they should pay attention to the fact that it is forbidden to wear metal objects or electronics.

Precautions when doing MRI: 1. If there are magnets in the body, this examination cannot be done, but if the implant in the body is confirmed by the surgeon as a non-magnetic object, MRI examination can be performed. 2. The following information should be explained to the technical staff:

whether there is a history of surgery; Whether any metal or magnetic substances have been implanted in the body, including metal contraceptive devices, etc.; the presence or absence of dentures, electronic ears, prosthetic eyes, etc.; presence or absence of drug allergies; Whether or not metal foreign matter has been splashed into the body.

It will not cause some damage to the body, because the speed of the MRI is very fast and will not affect the patient's body at all.

Yes, if you do an MRI, there will be some radiation, and there will be some damage to the body, but these injuries are not large, and the human body can bear it.

Since MRI is magnetic field imaging and is not radioactive, it is harmless to the human body and is very safe. The cause of your headache and dizziness has nothing to do with MRI, or is it caused by high blood pressure, or cervical spondylosis, find out the cause system**.

Generally, there are more people who do MRI examinations, and it may take the next day to do them after making an appointment, especially in large public tertiary hospitals, which is especially difficult to make an appointment, but now there are many private imaging centers, which do not need to make an appointment, and the effect is better.

It is understood that due to the interference of metal with the external magnetic field, patients must remove all metal objects from their bodies before undergoing MRI examination. Do not wear magnetic objects such as watches, metal necklaces, dentures, metal buttons, metal contraceptive rings, etc. In addition, a pacemaker is worn, and there are paramagnetic metal implants in the body.

Magnetic resonance imaging (MRI) is not available for metal clips, stents, plates, and screws. Magnetic resonance imaging of the upper abdomen (such as liver, pancreas, kidney, adrenal glands, etc.) must be performed on an empty stomach, but you can drink enough water before the examination, which is conducive to a clearer boundary between the stomach, liver, and spleen.

Detection of lesions: MRI is a new medical imaging technology that uses the principle of MRI, which has excellent diagnostic functions for the brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, prostate and other solid organs, as well as the heart and large blood vessels. Compared to other adjunct tests.

MRI has the advantages of multiple imaging parameters, fast scanning speed, high tissue resolution and clearer images, which can help doctors "see" undetectable early lesions, and has become a powerful tool for early screening of tumors, heart diseases and cerebrovascular diseases.

1 If you are doing an abdominal examination, it is best to fasting for 4 to 6 hours on the day of the examination to prevent food from interfering with the imaging. If it is a test of other areas, there is no need to fast.

2. There are no metal objects to be done for MRI, and all metal objects must be removed when entering the examination room. Because there is a strong magnetic field that adsorbs iron during the examination, it is necessary to remove jewelry and iron dental implants in order to achieve a good examination effect and avoid injury.

3. During the examination, there may be relatively loud noise, in order to prevent hearing damage, you can bring earplugs.

4. When lying in the MRI machine, keep the body still, do not move at will, and do not let the possibility of re-examination. At the same time, don't be curious, touch the inner wall of the machine, as well as the wires, which may cause harm to the body.

1. Magnetic resonance imaging is not suitable for pacemaker or metal in the body: magnetic resonance examination is imaging under the principle of nuclear magnetic resonance, and its examination environment is magnetic field, so for some patients with pacemaker or some special metals in the body, it is not recommended to do magnetic resonance examination for this type of patient.

2. Pay attention to psychological adjustment: In addition, in the process of magnetic resonance slow inspection, due to the resonance, some relatively large sounds will be generated, which may cause certain panic and other psychological discomfort to the examinee. It is recommended that the MRI patient make psychological adjustments on his or her own during the examination and not panic.
