Magnetic resonance imaging is the process of visualizing the human body through images created by the magnetic resonance of radio waves. It is a non-invasive procedure and requires the patient to enter the field of magnetic and radio waves performed by various organs of the human body as they pass through the body; and they are filmed on imaginary screens to understand the shape and size of the internal organs. The results of the MRI scan service were taken from a computer that took pictures of the target organs.

Why perform an MRI Scan?

An MRI scan is performed when the internal information about the human body should be carefully examined. It is important to note that the scope of information obtained through computer-generated MRI scans is not available through X-rays and CT scans. MRI scans provide clear and accurate images of the categories of internal anatomy including details of soft tissues, organs, and bone. MRI scans allow doctors to diagnose early stages of any disease or ingrowth.

Types of MRI Scan?

Although the basic techniques are similar, the different types of MRI scans available in radiology are classified on the basis of the target body scans. These are as follows:

Abdominal MRI: Examines the abdominal area of the body.
Chest MRI: Examines the chest or thoracic area of the body.
Cranial MRI: Examination of the head including the brain and skull.
Cardiovascular MRI: Examines the heart and its various parts for specific images.
Spinal MRI: Detects spinal area. There may be a partial scan of the spine or a complete scan depending on the need.

Preparing for an MRI Scan?

MRI scanning is a non-invasive procedure and therefore, there is a small amount of preparation required for imaging. The patient’s body is not exposed to radiation during the scan. Patients are asked to change into hospital uniforms and may not be allowed to eat or drink before MRI scans. Your prescribing instructions will determine whether food is allowed before the scan.

To be screened by a comparison agent, the patient may be injected with a comparison agent with an IV line. MRI scan is performed after the injection. Photos before and after the injection are essential for complete photography. In patients suffering from claustrophobia or who are afraid to enter confined spaces, appropriate counseling is provided to prepare them for the scan. Some of them may ask for a mild sedative to help the patient feel drowsy. Ear plugs are usually provided to the patient so that they are not affected by continuous clicking sounds inside the MRI scanner.

What happens during an MRI Scan?

The MRI scanner is located in a separate glass enclosure on one side and has a satellite phone for the specialist to talk to the patient on the scanner. The patient is asked to lie comfortably on a moved scanner table.

Once the patient is comfortable, the table is slowly moved into the opening of a large cylindrical MRI scanner that holds the magnet. As the device allows radio waves to pass through a patient’s body, the machine constantly scans images of various body parts.

The patient may hear a continuous knock on the door while the images are clicked. The Radiology specialist discusses the patient further and reviews it with the following steps. Throughout the photography process, the patient needs to remain steady to avoid blurring the images taken and stored on a computer. The radiologist examines all the images to clarify and complete the doctor’s prescription before announcing the MRI scan.

How long does an MRI Scan take?

An MRI scanner can take anything between 20 and 60 minutes, depending on the size of the data and the scan that the doctor has decided to diagnose.

What happens after an MRI Scan?

After the MRI scan is completed, the patient can move quickly and resume normal activities. If the patient is slow to relax, there should be a responsible adult to accompany him or her home.
