The modern medical world today is inseparable from a device called MRI (Magnetic resonance imaging), a sophisticated scanner on CT-Scan. I am writing this not because I am a doctor but this is just experience as a patient. Hehehe .. Three years ago I had to undergo an MRI examination to confirm the illness I suffered, whether Gullain Barre Syndrome (GBS) or Mielitis Transversa. GBS and Mielitis Transversa is an autoimmune disease that has clinical symptoms that resemble one of the patients will become paralyzed in a relatively short time and to ensure it must pass an MRI examination. I went through 2x MRI before finally doctors sentenced that my illness was Mielitis Transversa. The first checks to scan the body as a whole while the second inspection only take a special image of the spine. What is MRI and how does it work? Online sources explain that magnetic resonance imaging (MRI) is a radiological examination using the principle of non-surgical magnetization, X-rays or radioactive substances. The magnetic field is used to process the magnetization of the body's hydrogen ions and with radio waves emitted to the computer to get the image of the body part to be examined. MRI can describe clearly and contrast various body organs such as digestive organs, heart, spinal cord, nervous system and others. The results are more obvious than X-ray and CT-Scan. MRI is very helpful for doctors to be able to pinpoint the diagnosis of a disease. MRI is a spectacular discovery in the world of health by Dr. Raymon Damadian from America with two colleagues. Larry Minkoff and Dr. Michael Goldsmith. First applied on July 3, 1977 after past 7 years of research. Nevertheless, the Nobel Prize for MRI discovery is not given to Dr. Damadian and his colleagues but fell into the hands of Peter Lauterbur of America and Peter Mansfield of England in 2003. Whereas Lauterbur and Mansfield only made technical improvements only from the discovery of the patented. Damadian before. In the early days of MRI application in medical field, the examination process can reach 5 hours. But with refinement, now MRI only takes 45 90 minutes. In the future the time will be shorter considering the progress of perfection of this tool sangt rapidly from time to time.
This tool is a tunnel / tube about 60 cm in diameter, the patient put by lying on a special table. For those who claustrophobia (phobia of the narrow room) should be consulted to calmly undergo the examination. My experience, the noise that emerged from this tool during the examination can make you dizzy. Various types of sounds are somewhat powerful after another during the inspection process. There is a sound resembling the sound of a car engine, a motor, a frog, a dog bark and so on. Dizziness khan .. hehehe .. The sound is muted by installing a walkman in the ear of the patient so that patients can divert attention through the songs being played. Before the patient's precision is provided with a button that can be pressed at any time to signal if any emergency is felt and requires quick handling. The temperature inside the tube follows the existing room temperature. One of the advantages of this tool, the patient does not need to be changed position of the body, the patient just lying relaxed while listening to the songs through walkman from beginning to end. The time required depends on the type of examination. When I first checked to take a picture of my whole body, I had to go through it for about 75-80 minutes (this is my guess because the number of songs I hear is 19 pieces with the assumption of 4 minutes per song hehehe). In the second examination, the picture taken only on the spine so that the time is only about 25 minutes (6 songs .. hehehe ….) MRI does not use X-rays and radioactive substances so it is safe when done repeatedly, also not cause pain in body. Because using a magnetic field it is very influential for those who have metal aids in the body such as dentures, pacemakers and others. Metallic aids can be shifted by powerful magnetic effects that harm the patient. Before the examination the patient was asked to make sure that no metal was lodged in his body including those outside such as rings, bracelets and earrings. From searching the internet I found no other information about the side effects of this tool. *** Sources: https://novaliaprasetyoviantri.students-blog.undip.ac.id/2009/12/12/tugas-imaging-diagnosis/ https://en.wikipedia.org/wiki/Pencitraan_resonansi_magnetik https: / /www.mitrakeluarga.com/bekasitimur/mri-magnetic-resonance-imaging/ Image source: https://novaliaprasetyoviantri.students-blog.undip.ac.id/
