What is an MRI scan?
Magnetic resonance imaging (MRI) is a diagnostic test used in the medical imaging field. It uses a magnetic field and radio waves to take pictures of the inside of the body organs. It is specifically useful for taking images of soft tissues, such as organs and muscles that are not visible on other imaging modalities.
An MRI can be taken as an X-ray of the water, although it is not actually an X-ray. In a plane x-ray, we see the hard tissue of the body, like bones. MRI scans the water, which makes it crucial for all soft tissues of the body that contain water. It provides high-resolution pictures or images that we cannot see through normal x-ray scanning.
How an MRI works
An MRI includes a table that slides into a large cylinder. There is a magnet inside the cylinder that generates a strong magnetic field when activated. Soft tissues consist of water molecules, and the magnetic field affects the substances (like protons) present in the water. Magnetized protons in soft tissue generate echoes in response to radio waves in an MRI scan. The computer then arranges these echoes into the images.
An MRI can take images of a patient’s body from almost any angle.
When an MRI is used for
MRI is used for screening examinations or to diagnose conditions that affect soft tissue, like:
- Tumors, including cancer
- Soft tissue injuries, such as ligament rupture
- Joint injury or disease
- Injury or disease related to the spine
- Injury or diseases related to internal organs, which include the brain, heart, and digestive system,.
What is screening, and why is it important?
A screening test is performed to detect potential health conditions or diseases in people who generally don’t show any significant symptoms of disease. The purpose of a screening test or investigation is early diagnosis or examination to reduce the future risk of the disease so that it is possible to cure the disease at the right time. Screening tests are not considered diagnostic but provide significant information about a health condition that has the potential to become a severe disease.
Health care imaging system in India:
India has made a tremendous advancement in the field of medical imaging, enabling healthcare professionals to detect diseases and conditions at their initial phase. Medical imaging techniques like x-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and nuclear medicine have improved the diagnosis and treatment of different diseases. With the rapid development of science and technology, medical imaging in India has become more reachable and affordable, enhancing the overall quality of healthcare services across the nation.
Preparation before taking an MRI
Food/Medicine: Patients can generally take food or medication in most MRI tests. Some specific MRI tests need some limitations.
Clothing: It is advisable to remove clothes and any kind of jewelry or ornaments at the time of imaging.
What you can expect: Imaging is performed in a large tube structure that is open on both sides. To get high-quality pictures, the patient should be still during the screening. Earplugs are used because of the loud noise generated during the procedure.
Allergy: Some MRI tests need to inject an intravenous contrast substance. If the patient has a history of allergy to the injectable substance, he or she should inform the physician prior to imaging. Accordingly, an alternate solution will be implemented.
Anti-anxiety medication: If the patient is taking any anti-anxiety medication that should also be informed and noted before the imaging procedure.
Strong magnetic environment: It is very important to check if there is any kind of metal in the patient’s body that can cause serious effects due to the high magnetic field of the MRI.
Based on your health condition, the physician may advise other preparations.
Some important conditions that have to be informed to the doctor include:
- If the pacemaker has been replaced.
- Implantable pump, such as an insulin pump.
- Pregnant or think you are pregnant.
- Injury from a gunshot
- Ever worked with metal (like a metal grinder or welder)?
- If you are unable to lie down for 30–60 minutes,.
Common diseases that can be diagnosed using an MRI
The MRI can detect a broad spectrum of diseases in various body parts. In the brain, it can help detect diseases like
- Tumors
- Alzheimer’s disease
- Multiple sclerosis
- Shots
In the spine, MRI can detect:
- Disc prolapse
- Spinal cord injuries
- Tumors of the spine
- When it comes to joints, MRI is often used to diagnose conditions such as:
- Arthritis
- Ligament tears
- Cartilage damage
The importance of MRI imaging in cancer detection
Imaging tests are the initial step in the management of cancer. It has been evident from the scientific study of eight common cancers that more than 90% of people are able to survive ten years after the initial stage of cancer is diagnosed. Improved imaging techniques like MRI provide early detection and diagnosis and help define the stage of cancer. Similarly, the enhancement of cutting-edge imaging procedures aims to catch cancer at an early stage and facilitate its management. Early diagnosis through MRI imaging screening is one of the main tools for reducing cancer deaths.
The following types of cancer can be diagnosed at an early stage through MRI imaging:
Lung cancer
Lung cancer leads to the death of 150,000 people every year. An MRI can screen for the initiation of lung cancer. This results in a 20% reduction in cancer deaths.
Breast cancer
Breast cancer can be detected initially by using MRI, ultrasound, mammography, and molecular breast imaging (MBI), resulting in higher rates of survival.
Cardiovascular diseases
Cardiovascular diseases impact millions of people across the globe. Imaging technologies such as cardiac magnetic resonance imaging and coronary angiography help identify structural changes, blockages, and other cardiovascular diseases. Early diagnosis of these conditions provides a rapid intervention, such as lifestyle modification, medication, or surgery, to stop further damage and improve heart health.
Neurological diseases
Imaging plays a vital role in the initial detection of neurological diseases, including stroke, Alzheimer’s disease, and tumors of the brain. Magnetic resonance imaging (MRI) gives extended images of the brain and helps to diagnose abnormalities. Early detection of neurological diseases gives a chance of early treatment, which results in better therapeutic outcomes and a better quality of life for patients.
Mapping the advancement of the disease
MRI imaging is useful not only for early detection of disease but also for monitoring disease advancement. It also provides information about the spread of cancer or the stage of cancer.
This helps the specialists analyze the patient correctly and ensure the correct management at the right time. Also enhance the chances of a cure and inhibit the recurrence as correct treatment can be established.
