Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses magnets and radio waves to capture detailed images of the body's internal structures. In today's fast-paced business world, MRI scanners are not only useful in clinical settings but have also found widespread applications in the manufacturing industry, research and development, and a host of other fields.
What is an MRI scanner?
An MRI scanner is a powerful medical imaging device that produces high-quality images of the body's internal structures without the use of ionising radiation. It consists of a large and powerful magnet, a computer, and a radiofrequency system. The machine generates a strong magnetic field that aligns the protons in the body's cells, which can then be manipulated using radiofrequency waves to produce images with remarkable clarity and detail.
How an MRI scanner work?
The science behind MRI scanners is fascinating. The first step in an MRI procedure is to lie down on a padded table that slides into the MRI machine. The scanner emits a powerful magnetic field that aligns the hydrogen atoms in the body's cells in a single direction. A radio wave is applied, causing a disturbance, and making the atoms jump. When the radio wave is turned off, the atoms emit a detectable signal, which can be picked up by the scanner's sensors.
The computer's algorithms then process these radio signals, constructing detailed images of the body's internal structures. This process can take anywhere from a few minutes to over an hour, depending on the part of the body being imaged.
Applications of MRI scanner
Although MRI scanners are primarily used in clinical settings for medical diagnosis, they have found applications in various industries, including manufacturing, research and development, and agriculture. The technology is compatible with various subjects, including metal structures, which make it a good option in the manufacturing industry for non-destructive testing, in identifying corrosive spots, and other internal defects in the structure. MRIs are useful in pre-clinical studies of animals, drug development, and research in microbiology.
Types of MRI machines
MRI machines come in different sizes and with varying specifications, depending on the manufacturer, and intended use.
Here are some common ones:
- Closed-bore MRI: It is the traditional kind with a big tube. Patients lie on a table that goes into the tube. It gives good pictures, but some people might feel claustrophobic.
- Open MRI: These have a more open design, so they are less confining. They are good for larger patients or those who can't lie flat. The pictures might not be as clear as closed-bore MRI.
- Wide-bore MRI: They are like a mix of closed-bore and open MRI. They have more space but still give good pictures.
- High-field MRI: These have stronger magnetic fields, so they give better pictures. They are often used for detailed imaging of the brain, spine, and joints.
- Low-field MRI: They have weaker magnetic fields but can be cheaper. They are used when super clear pictures aren't needed.
- Portable MRI: These are small and can be moved around. They are handy for places where regular MRI machines cannot go, like emergency rooms or remote areas.
Safety and risks of MRI
Despite being considered a safe imaging procedure, MRI scanners involve risks that need to be managed. The powerful magnetic field generated by the scanner can cause adverse effects on metal implants in the body, leading to injury, burns, seizures, and other medical emergencies. In addition, contrast agents used in MRIs have led some patients to experience mild to severe allergic reactions.
Future trends in MRI technology
MRIs will continue to evolve, offering more advanced, precise, and efficient imaging technology. We can expect advances like a merger of real-time imaging to engage with augmented reality. Using robotic platforms that can manipulate the direction of the MRI machine to capture microscopic structures Fluorine-19 as an MRI tracer aims at enabling cancer diagnosis from non-fluorescent MRI diagnostic imaging.
Preparing for an MRI scanner procedure
It is essential to follow specific instructions and recommendations before undergoing an MRI procedure. Patients should avoid wearing metallic objects, carry their medication and communicate with their physicians about recent MRI or any implants in their body.
What to expect during an MRI procedure?
Patents often experience discomfort during the MRI procedure. People who have a hard time laying down or being in tight enclosed spaces may experience discomfort lying on the bed. There is no pain during the scan, only a loud metallic sound from the machine, which may cause discomfort or cause hearing problems.
Types of MRIs and their uses
There are different apps of MRI machines arising from their ability to scan various parts of the body by immobilising protons in the body cells that absorb hydrogen. They include spine imaging, brain imaging cancer, breast imaging, musculoskeletal imaging, and heart and vessels imaging.
Risks and benefits of MRI technology
MRI procedures have risks and benefits that need to be examined before undertaking a procedure. The primary risks are associated with the contrasting agents, as they expose patients to severe reactions, and MRI machines might cause injury through procuring metal implants in patients. MRI diagnostic imaging has several advantages that make it a top-rated diagnostic procedure, including advanced technology, no ionising radiation, and non-invasive.
Post-MRI care and considerations
After the MRI scan, patients are urged to drink plenty of fluids to flush out the current trace contrast formally ingested, and some patients may need a rest. Depending on the results of the MRI scan report, doctors may schedule a follow-up with their patients.
Advances in MRI technology
Improvements over the years have created new domains for MRI technology. The multi-parametric MRI involves artificially embedding intelligence into the imaging technologies that are useful in the detection of broken cartilage or tumours that may trigger cancer.
MRI machine prices
At the hospital store, prices for MRI scanners range from INR 1.4 Crore to INR 10 Crore, depending on the type, brand, and model. The specific cost varies based on the chosen model.
