An Overview of Magnetic Resonance Imaging

MRIs are medical procedures that create a magnetic field around atoms inside the body using radio waves. These waves are then emitted from the magnet and picked up by a powerful antenna. These waves travel through our bodies and are then processed by computers, which then turn the information into 3-D images. MRIs can be used for diagnosing problems in the brain and spinal cord. They also can target the brain stem.

The patient must be still for the entire procedure. While inside the machine, an MRI technologist will speak with the patient. Many times, the patient is given music or headphones to help him or her relaxes. An IV line can be used for injections of contrast material such as gadolinium to enhance details. The patient must be still during the examination. Any movement could cause blurring.

The patient must remain still during the procedure and should not move. You should get rid of all jewelry and credit cards. The technologist then will be in another area and will watch over the patient. The patient will be capable of speaking to the technologist via a microphone. The MRI technologist uses specialized equipment and small coils to place over specific body parts. Clearer pictures are then produced. MRI is a highly safe procedure. Patients should feel comfortable throughout the entire process.

A session with an MRI takes about 30 minutes. A small coil could be placed on one body part. The MRI technician will then transmit a radio wave to that area. During this time the patient will not move. The MRI will then create a strong magnetic field around the patient. The radio waves will then be directed to the particular part of the body that is being examined. During MRI the patient will feel nothing.

The MRI machine consists of a large, heavy-gauge tube. A small coil is placed over the area that is being imaged. The patient will be required to stay still for the full duration of the scan. They must also take out any metallic objects. They must also take out all credit cards. The technologist also needs the patient’s insurance identification card as well as relevant X-rays. The MRI machine creates a strong magnetic field around the patient and directs the radio waves at the specific part of the body to be imaged. The patient won’t feel the radio waves or magnetic field.

The MRI machine creates a strong magnetic field around the patient. The radio waves are directed towards the part of your body being imaged. The signal from the MRI will be broadcast to a nearby radio station. They can communicate with each other via intercom. This will allow the patient and technologist to communicate. The MRI will take around half an hour.

During an MRI procedure, the patient lies down on a special MRI table. He or she may lie down on a table or in a chair outside of the machine. A small coil is applied to the body area being imaged. The patient’s arms will be placed at their sides. The headrest will be placed onto a headrest. The technologist will place a small coil above the body part that is to be imaged. The radio waves travel to the affected parts of the body.

Patients are required to remain still during an MRI for around thirty minutes. The patient should feel comfortable and should take off any jewelry or metal objects. They should also take off any undergarments which could interfere with the MRI. If they are not compatible they can be left at the home. An alternative is to get a hospital gown. Comfortable clothes are recommended for the patient. During an MRI the patient should wear comfortable clothing.

The MRI machine looks like a narrow, long tube with open ends. It features a small headrest that the patient must use to lie down on his/her back. The technologist will place small coils around the body. The coils create detailed images by sending and receiving radio waves. During an MRI, a patient will be placed on a movable bed with a pillow under their chest.
