MRI, or magnetic resonance imaging, is a technique that allows doctors to take images of the inside of the body without surgery. Unlike X-rays, MRI scans use a large magnet and radio waves and are not associated with ionizing radiation. Such a modality of visualization is critical in detecting different ailments and managing their therapy.
Given how unpredictable life is and how health issues can occur at times, looking for an MRI near me center is a good idea. But what is it, and how does it take place? Are there any precautions, and when do you need to go for an MRI? If you have any of these questions, then this post is for you.
What is an MRI Scan?
MRI scans are non-invasive and take several images with high resolutions with the help of magnetic fields and radio waves. These images give a clear picture of the soft tissues and the medical conditions that might be unnoticed by the other examinations. In the case of injuries, tumors, and diseases of internal organs, the scan is very useful.
On the other hand, methods such as X-ray and CT scans can be used to determine issues associated with bones rather than soft tissue disorders. For instance, if used to detect broken bones, an X-ray will produce better results than an MRI, while in the case of spinal, joint, or ligament problems, an MRI scan will be the best option.
When is an MRI Scan Needed?
Your physician may ask you to go for an MRI for many reasons, depending on your symptoms or past medical history. It is often used to diagnose:
- Sprained ligaments, arthritis problems, or sports injuries.
- Tumors or cancerous growths.
- Organ disease of a specific organ only, such as the heart, brain, or stomach disease.
- Dorsal injuries or disorders.
The level of detail that one gets from an MRI enables more accurate formulation of treatment procedures. In some circumstances, an MRI may be used in preference to other imaging techniques, such as CT scans or ultrasonography. However, make sure to get it done from a reputable clinic and ask a doctor for recommendations for accurate reports.
How Does an MRI Scanner Work?
An MRI scanner is a large circular and cylindrical structure that looks like a tunnel. When you lay inside, the machine generates a very forceful magnetic field and directs radio waves through and around your body. These waves generate signals from certain atoms in your body, and the signal is then converted to pictures on a computer screen.
The process enables doctors to look at the body from different perspectives. However, patient immobility is important during the scans because any movement can cause blurring of the images.
Preparing for an MRI Scan
MRI preparation is easy but necessary if the results of the scans have to be of good quality. Patients are free to consume food and beverages and even take medicines they need without the prescription of their doctor. Certain specialty scans may need one to fast or even drink a lot of water before the scans.
For the process, it is required that you only have no metallic objects on your body, no rings, no piercings, no watches, etc. It is dangerous to work with metal since it disrupts the magnetic field and can suddenly transfer dangerous currents. Let your doctor know if you are an implant wearer, for example, a pacemaker or a stent.
The overly anxious or claustrophobic patients can ask their physicians for mild anxiolytics. The clinic will bring earplugs just in case you may be affected by the noisy MRI machine. MRI scans for pregnant women are not advised to be taken during the first three months of pregnancy except for emergencies.
