Magnetic Resonance Imaging Definition
Magnetic resonance imaging (MRI) is a picture of imaging of the body part taken using strong magnetic power around the limbs. Unlike the CT scan, MRI does not use X-ray radiation and is suitable for detecting soft tissues such as cysts or tumors, but imaging with MRI is more expensive than using a CT scan.
Magnetic Resonance Imaging (MRI) is a technique used to produce images of internal organs in living organisms and also to find the amount of water content in the geological structure. It is commonly used to describe pathology or changes in the physiology of live muscles and also estimate the transparency of the stones to hydrocarbons.
MRI History
The discovery of MRI does not appear suddenly, but through the development of the science that supports the realization of MRI technology.
There are a few different names that have a big enough one to make it happen.
Mendeleev and Lothar Meyer in 1869 compiled atomic elements with their periodic system.
Ernest Rutherford, Niels Bohr and James Chud in 1911 are in theory about atomic structures.
Later Felix Block and Edward Purcell both received a Nobel Prize in Physics in 1952 revealing the behavior of the nucleus like a small magnet, which can perform spin and precessing with the based on the Larmor formula (to be discussed) that is the foundation of MRI.
In 1960, a physicist who could be considered the most meritorious in the development of MRI was Raymond Damadian has carried out the barrage of research and is able to distinguish malignant tumor tissues and normal tissues.
Followed later in 1974 he demonstrated a rat tumor roughly with an MRI image and in 1976 produced the image of a human body by requiring a 4-hour inspection time.
In 1977 with Paul Lauterbur perfected and officially became one of the medical imaging instruments.
Reasons for Magnetic Resonance Imaging
MRI is one of the ways doctors examine and produce images of high resolution organs, tissues, and skeletal systems. It can then help your doctor diagnose problems around your health. MRI tests can also be used as one of the determinants of treatment and evaluate the effectiveness of therapy.
Here are a few reasons why you should do an MRI, including:
Brain and spinal cord
MRI is most commonly used as a method of imaging the brain and spinal cord. MRI of the brain can also be utilized to consider the steps of brain surgery by identifying important language areas and movement control.
Some diseases of the brain and spinal cord can be diagnosed with MRI, such as strokes, tumors, aneurysm, multiple sclerosis, accidental brain injury, inflammation of the spinal cord, as well as eye and inner ear disorders.
Heart and blood vessels
MRI performed on the heart or blood vessels aims to see several things, such as the size and function of the heart chamber, thickness and movement of the heart wall, as well as the degree of damage from heart attack or heart disease.
In addition, MRI can also be used to detect structural problems in the veins, such as the walls of weakened blood vessels or tears, and inflammation and blockage of the blood vessels.
Bones and joints
In parts of bones and joints, MRI is apparently able to help evaluate conditions such as bone infections, spinal disorders and pads of spinal nerves, tumors of the bones and soft tissues, as well as inflammation of joints. It can also find out abnormal conditions in the joints caused by physical injury due to accidents or recurring injuries.
Breast
MRI can be used in women who are at high risk of developing breast cancer or for those with dense breast tissue. This step is effective for providing additional information in detecting the presence of breast cancer cells in addition to using mammography.
Other internal organs
MRI can also be utilized to detect tumors or other disorders of various internal organs, including the liver, kidneys, spleen, pancreas, uterus, ovaries, pro**state and tes**ticles.
MRI scan side effects
Although it does not use radiation as in a CT scan, the MRI examination uses a strong magnetic field. This magnetic field is so strong that it is able to affect any object made of metal around it. So the risk is very large for patients who have metal implants, such as pacemakers. This patient cannot enter the MRI machine. Other risks and side effects include:
- Noise: there is a noise up to 120 decibels in certain MRI examination machines. The patient may be given an earplug before entering the machine.
- Nerve stimulation: twitching sensations that arise from processes inside an MRI machine.
- Contrast substance problems: for severe kidney failure patients who require dialysis may be problems with the use of gadolinium contrast substances.
- Pregnancy problems: it is recommended that pregnant women do not undergo MRI examinations in the first trimester of pregnancy in relation to the use of contrast substances that may affect the fetus.
- Claustrophobia: MRI machines are generally enclosed around them and narrow, so they are uncomfortable for people with claustrophobia. But now there is a new MRI machine that is more open so that it is more friendly for patients who have a phobia of narrow and closed places.
