An Overview of Magnetic Resonance Imaging

MRIs, which use radio waves to create a magnetic field around atoms of the body, are medical procedures. These waves are created by the magnet and picked up by an antenna. These waves travel through your body to be processed by a machine that then transforms them into 3-D pictures. MRIs can diagnose and treat problems in the brain or spinal cord. They can also target the brain stem.

The patient must remain in a still position throughout the procedure. The MRI technologist will communicate with the patient during the procedure and then monitor the scan. To help patients relax, they may be given music or earplugs. An IV line can be used to inject contrast material, such as gadolinium. This will enhance certain details within the image. The patient must remain still during the examination. Movements can blur the images.

The patient must be still and seated throughout the procedure. They should also wear loose clothes. They must take off all jewelry and credit card. The technologist will then go into another room and monitor the patient. The patient will then be able to speak to the technologist through a microphone. The MRI technologist then uses specialized equipment for placing small coils over the body to produce clearer images. MRI is a safe procedure. Patients should feel relaxed throughout the process.

A 30-minute MRI session is typical. A small coil might be placed on an area of the body. A radio wave will be sent by the MRI technician to the affected area. The patient will remain motionless during this time. The MRI will create a magnetic field around the patient. Radio waves will then be directed at the specific part of the body being scanned. During MRI, patients will feel nothing.

A large, metallic tube is the MRI machine. A coil is placed on the area of the body to be imaged. The patient will need to remain still for 30 minutes. They must also get rid of any metal objects. They will also need to take out their credit cards. The technologist may also require the patient’s relevant X-rays and insurance identification card. The MRI machine creates a magnetic field around them and directs radio waves towards the part of their body that is being imaged. The magnetic field and radio waves are not felt by the patient.

The MRI machine creates a strong magnetic circle around the patient. The radio waves travel to the specific part of the body that is being imaged. Radio waves will be sent from the MRI machine to the radiologist. They can also communicate using an intercom system. This will allow patients to communicate with their radiologist or technologist. The MRI process will take approximately half an hour.

During an MRI the patient lies down in a special MRI machine. The patient can either sit in a chair or lie on a mattress outside of the machine. A coil is placed on the part of the body being imaged prior to the MRI. The coil will be placed on the side of the patient’s body. The headrest is placed on top of the headrest. A small coil will be placed over the area to be imaged by the technologist during an MRI. The radio waves will travel to the relevant parts of your body.

An MRI requires that a patient remain still for approximately thirty minutes. While they should be comfortable, they must remove the jewelry and other metallic objects. They should also get rid of any undergarments that might interfere with the MRI. They can be kept at home if they’re not compatible. Alternatively, a hospital gown may be provided. The patient should wear comfortable clothes. During an MRI scan, any metal should be removed from the patient’s body.

The MRI machine appears like a long, narrow tube that has open ends. It has a small headrest so the patient can lie on their back. The technologist will attach small coils to the affected areas. These coils emit and receive radio waves that create detailed images. During an MRI the patient will be placed on a movable desk with a pillow beneath his or her chest.
