How the Mri Procedure Has Impacted Society

Table of Content

MRI scanning, an undeniable technological advancement, has had a profound effect on society. It empowers doctors to diagnose and possibly treat life-threatening illnesses, making its positive impact significant despite criticism from skeptics.

Introduction of Magnetic Resonance Imaging (MRI) scan has significantly advanced medical technology, aiding in the diagnosis of potentially fatal diseases. Consequently, society benefits greatly as medical professionals are able to detect and treat diseases at early stages. Without MRI tests, many lives that could have been saved may be lost. Although there are drawbacks, the overall advantages of MRI outweigh the disadvantages.

The MRI is a significant advancement in providing healthcare professionals with tools to diagnose and heal individuals worldwide who suffer from illness or injury. Dr. Raymond Damadian, a physician and scientist, spent a considerable amount of time conducting experiments in order to develop a machine capable of using magnets to scan the body. With the assistance of some graduate students, he built a magnetic device in hopes of generating an internal image of the human body. Being unable to find any volunteers, Damadian decided to be the first person to undergo the procedure.

When Damadian entered the device, nothing happened. He believed his years had been wasted on an unsuccessful invention. However, a colleague proposed that he might be too large for the machine. A graduate student stepped forward to try it out. On July 3, 1977, the first MRI exam was successfully performed on a human being. It took almost five hours to generate a single image. The original machine, affectionately known as the “Indomitable,” is currently under possession of the Smithsonian Institution. Not long after, accessible MRI scanners for human use were developed and capable of producing internal body images.

Current MRI scanners have the ability to generate detailed 2D and 3D images of the human anatomy. The use of magnetic resonance imaging (MRI) scanners has significantly increased in recent years. Medical professionals may recommend MRI scans for diagnosing a range of conditions such as multiple sclerosis, brain tumors, ligament tears, tendonitis, cancer, and strokes. An MRI scan offers accurate visualization of internal structures without requiring surgery. The MRI scanner is an advanced device that can detect abnormalities that other diagnostic tools like x-rays and CT scans cannot identify.

Dr. Lawrence M. Davis (2009) explains that MRI and CT scanners work in a similar way, creating body images in sections like sliced bread. However, the main difference is that MRI does not use x-rays. Instead, it relies on a strong magnetic field and radio waves to produce detailed computerized interior visuals. This imaging technique is commonly used for examining the brain, spine, joints, abdomen, and pelvis.

Magnetic resonance angiography (MRA) is a specialized type of MRI exam that examines blood vessels. MRI scans are versatile and view various parts of the human body, including bones and tissue. In our society, MRI scans have multiple uses for the brain. They provide detailed images and help patients with conditions like headaches, seizures, hearing loss, and blurry vision. If abnormalities are found on a CT scan, further investigation can be done using MRI scans.

The head coil is used in a brain MRI to obtain detailed brain images. It surrounds the patient’s head without touching them, allowing visibility through gaps in the coil. In contrast, a spine MRI is commonly employed to diagnose issues such as herniated disks or spinal canal narrowing in patients experiencing neck, arm, back, or leg pain. Moreover, it is considered the best method for detecting recurring disk herniation in individuals who have had previous back surgery.

A bone and joint MRI is utilized to assess the state of bones, joints, and soft tissues, enabling the detection of injuries to tendons, ligaments, muscles, cartilage, and bones. In contrast, an abdominal MRI is typically conducted to further examine abnormalities identified in ultrasounds or CT scans. This examination concentrates on specific organs like the liver, pancreas, and adrenal glands. Regarding female patients, a pelvic MRI provides a more extensive evaluation of the ovaries and uterus and is frequently employed for follow-up on abnormalities discovered in ultrasounds.

Male patients may undergo pelvic MRI for prostate cancer assessment. Magnetic resonance angiography (MRA) is utilized to visualize blood vessels in the neck and brain, identifying areas of constriction or dilation. Moreover, MRA typically assesses abdominal arteries supplying blood to the kidneys. The MRI procedure offers several advantages, especially its ability to generate images of almost all body tissues.

Dr. Carl J. Brandt (2011) states that MRI scans are beneficial for examining the brain and spinal cord because they can produce clear images even in the presence of bone tissue. The detailed pictures provided by MRI scans make them the most effective way to detect both benign and malignant brain tumors. Furthermore, these scans can also determine if a tumor has spread to nearby brain tissue.

The technique not only allows us to explore different aspects of the brain, but it also helps us visualize abnormal tissue strands related to multiple sclerosis, identify changes caused by brain hemorrhage, and determine if the brain has suffered from oxygen deprivation as a result of a stroke. MRI scans have several advantages including their safety for individuals who may be susceptible to radiation effects like pregnant women and infants since they do not involve radiation exposure.

MRI scans have numerous benefits as they excel in visualizing soft tissue structures, such as ligaments, cartilage, and various organs including the brain, heart, and eyes. Additionally, they offer valuable information about blood flow within specific organs and blood vessels which helps in identifying and managing potential circulation problems like blockages. Overall, MRI is a safe procedure with no risks for patients unless they have specific metal implants.

Although the MRI procedure has many advantages, it is important to recognize that like any diagnostic test, it does have potential risks. One major drawback is that individuals with metal in or on their bodies may have limitations. However, patients with metal implants like hip or knee replacements can still undergo an MRI, but not right after their surgery.

Certain medical devices, like pacemakers, implanted pumps, and nerve stimulators, cannot be used with MRI machines because they may fail or get damaged. It is crucial for patients who have had surgery or have metal in their body to inform the technologist before the scan. This includes metal from past injuries or accidents. Occasionally, an MRI dye might be injected during the exam. Importantly, this dye is safe and different from the contrast agent or dye utilized in x-ray or CT scans.

Allergic reactions to the contrast used are rare but possible. To avoid complications, it is important for the patient to communicate with the physician and technician beforehand about any potential risks. Furthermore, there are concerns regarding the long-term adverse effects of magnetic field exposure on the technician who performs the scans.

In 2009, Sir William Stewart from the Health Protection Agency raised concerns about the increasing strength of magnetic fields in MRI machines, despite acknowledging their undeniable benefits for accurate clinical diagnosis. It is important to highlight that both patients and medical staff may be exposed to high levels of magnetic fields. However, there is a lack of information regarding potential long-term negative health effects.

Following the suggestion of an independent panel, he has declared his plan to investigate the potential connection between regular exposure to magnetic fields from MRI scanners and increased cancer risks. Although there may be varying viewpoints on its safety, this theory has not been verified yet. Nevertheless, it is imperative for our society to continue benefiting from MRI scans. Overall, these scanners have a significant positive impact on our society.

MRI scans have revolutionized medical diagnostics by accelerating the detection of diseases that previously necessitated autopsies. This technology is vital for understanding the anatomy, functionality, and development of the human body. By utilizing this information, healthcare can be improved and made more efficient.

Despite potential drawbacks, the aforementioned process plays a vital role in fostering a healthier society. The advantages it offers outweigh any criticisms from skeptics (Brandt, 2011; Davis, 2009; Stewart, 2008).
