Magnetic Resonance Imaging (MRI Scan): Safety & Side Effects
Magnetic resonance imaging (MRI) is an advanced medical imaging procedure that is commonly used in radiologic technology to create digital images of the internal structures and the physiology of your body. MRI scanners produce images with the help of highly powerful magnets, radiofrequency gradients, and electromagnetic fields to produce images of your organs on the tissue in your body.
With MRI, doctors can monitor the health of your organs and tissues by using magnetic resonance imaging techniques to produce digital images. A typical MRI scan can take a variety of images of your organs, brain, and other areas of your body; it is able to examine them at different stages in your body: from the early stages of the disease to the late stages of the disease.
In MRI, images are created using a magnetic field; this magnetic field is made up of many strong magnetic fields parallel to each other and perpendicular to each other. The strong magnet fields are called active coil magnetic resonance. The high-frequency radio frequency gradient is called x-ray pulses.
Magnetic Resonance Imaging is performed for the detection of abnormalities that are not otherwise visible to the naked eye
The most common areas that can be examined with magnetic resonance imaging in the brain. These include
- Blood vessels
- Pancreas, and
- Other areas of your body that can produce tumours.
It is possible to see the tumours in the absence of opening your eyes. Magnetic resonance imaging can also be used to detect tumours in the digestive tract and breast tissue. MRI scanners have come a long way in recent years, becoming more affordable and useful in modern medicine. Today’s MRIs can take pictures and videos of your brain at different angles, as well as being able to take multiple images simultaneously.
It can be used to examine the brain of someone who is in a coma, which will provide a clearer image than can be acquired with traditional CAT or MRI scans. MRI can be used to examine people suffering from Alzheimer’s disease and Parkinson’s disease, where doctors are still not sure how much they can do for patients.
Many patients with health problems such as
- Cerebral palsy
- Heart disease, and
They are capable of undergoing MRI scans. If a patient does not respond well to standard Computed Tomography (CT scans), they can opt for MRI scans as a second option. In a Positron Emission Tomography (PET scan), a probe of radioactive material is used to make images of parts of the brain.
Magnetic resonance imaging has a number of benefits. One of the biggest benefits of MRI is the fact that the imaging can be performed in a small environment; in fact, MRI has become the standard diagnostic method used in many hospitals around the world.
Patients with severe conditions may require frequent imaging, which means the patient may need several imaging sessions. Another advantage of MRI is that it can show many areas of damage in one scan, thus reducing the chance for surgical complications.
The risks and side effects of Magnetic Resonance Imaging scan
Magnetic Resonance Imaging scan is a painless radiology technique that has the advantage of avoiding x-ray radiation exposure. There are no known side effects of an MRI scan. The benefits of Magnetic Resonance Imaging scan relate to its precise accuracy in detecting structural abnormalities of the body.
Patients who have any metallic materials within the body must notify their physician prior to the examination or inform the Magnetic Resonance Imaging staff. Metallic chips, materials, surgical clips, or foreign material (artificial joints, metallic bone plates, or prosthetic devices, etc.) can significantly distort the images obtained by the MRI scanner.
Patients who have heart pacemakers, metal implants, or metal chips or clips in or around the eyeballs cannot be scanned with Magnetic Resonance Imaging scan because of the risk that the magnet may move the metal in these areas. Similarly, patients with artificial heart valves, metallic ear implants, bullet fragments, and chemotherapy or insulin pumps should not have Magnetic Resonance Imaging scanning.
Patients suffering from diabetes, cancer, and Alzheimer’s disease are the most often treated by MRI in clinics throughout the world. Some of these patients do not respond well to standard CAT scans, and MRI offers a more complete picture of their health problems.
MRI is also used as a screening test to assess women’s breast cancer and gynaecological tumours. Because the images produced with MRI can show so many details, a more detailed diagnosis can be made with a CT scan.
In many situations, magnetic resonance imaging can provide a definitive diagnosis of a medical problem, allowing doctors to prescribe medicines or surgery for specific ailments. With MRI, doctors can monitor the health of their patients, but the true cause of their problems may not be readily apparent.
