Applications Of Quantum Mechanics Of Magnetic Resonance Imaging Technology

One of the biggest advantages of MRI equipment is that it can be used to diagnose medical conditions in the heart, breast, bones, spine, and brain. This is the only imaging equipment, which can be used to diagnose issues, in all the above-mentioned parts of the body. The equipment can be used to identify stroke and blockages in the circulatory system, cardiovascular conditions, tumors, and injuries. There is an excellent return on investment in the MRI because of the variety of uses it has in a clinical setting (Keefer, 2011).

MRI uses the body’s natural magnetic properties to formulate an image of the soft tissues. It does this by using the hydrogen atom nucleus which has a single proton and is a spinning charged particle. The human body is made up of 70% water, which is hydrogen and oxygen. Those hydrogen nuclei (protons) spin inside the body, creating their own magnetic field. They are orientated randomly and cancel each other out when no field is applied.

Then, to check if the brain has suffered damage, if deemed necessary, the doctor will take a CT scan of the brain. The doctor will look for evidence of bleeding under the skull or within the brain tissue.

Magnetic Resonance Imaging (MRI) is a way of medically imaging the body with the use of a magnetic field and radiofrequency waves. (1) As image quality of MRI continues to improve, more MRI exams are being ordered. Increasing MRI exams leads to increased wait times. Due to current wait lists, the health status of patients may decrease, influencing the type of treatment the patient will require once removed from the wait list. (7) The advances in technology have increased in the past decade, with MRI procedures are vastly growing to provide superior diagnostic quality compared to other modalities. New technologies are also allowing for faster scan times and further increased image quality. (9)

MRI’s are one of the many pieces of technology we use to change lives. Without them, many people would be suffering from aggressive diseases and left clueless as to what is happening to them. There are other ways you can find out what illness someone has, but MRI’s “detect diseased or injured tissue more accurately, safely, and efficiently than any other medical imaging technique.” (Raymond Damadian, Inventor of the MRI).

Magnetic resonance imaging (MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. MRI also may show problems that cannot be seen with other imaging methods.

The MRI scanner beside having magnetic fields it also creates radio waves that are sent from the scanner to into your body. Usually your local hospital where you will be attending should give you information about how they use this scanner and what is it required for you to

Obese patients might not be able to have the exam completed if they exceed the set limitations. In order to accommodate to larger patients MRI has "open" scanners, which provide more room for patients getting rid of the claustrophobia feeling. Since this article is referring to people who have congenital heart disease, they will often be sent to a 1.0 Tesla open cardiac magnetic resonance scanner (CMR). These particular scanners require the patient to have their abdominal area inside of the bore making the open scanner more beneficial compared to a closed bore scanner. Ideally, it would make sense for all locations to have open scanners to help patients feel more comfortable, however the machines are only 1.0 Tesla and are highly expensive. There are advantages and disadvantages of the 1.0 Tesla. Sixty-five patients were involved in this article study taking a closer look at the effectiveness of the open scanners. Of the sixty-five people, ten of them were required to have their exam completed in the open scanner because of larger body size or claustrophobia. In the end, four of them were able to complete the study in the open scanner without

One effective test they use is called the Glasgow Coma Scale test. During this 15 point test the doctor checks the patient’s ability to follow directions and move their eyes and body parts. This test is based and scored on a numerical scale; the higher the score the patient was able to obtain because of their ability to follow the directions means the more mild their injury is. Computerized Tomography (CT) scans and Magnetic Resonance Imaging (MRI)s are also other tests used to help determine the damage done to the brain. A CT scan uses series of x-rays that will depict a detailed view of the brain easily showing any fractures, hemorrhage, contusions and any brain swelling. A MRI scan sends magnetic radio waves throughout your body to give doctors a look at the organs inside. The doctors of Medline Plus describe how MRI’s work stating that, “Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. During the scan, you lie on a table that slides inside a tunnel-shaped machine. Doing the scan can take a long time, and you must stay still. The scan is painless.” (“MRI Scans”).

Have you ever wondered how waves affect medical imaging? Sound waves are a big part of why and how medical imaging is used today. In this essay I will be explaining the application of sound waves in medical imaging, stating why medical imaging is needed, and telling you how the process of medical imaging works. I feel that medical imaging such as ultrasounds are a great use for technology. If medical professionals didn't have medical imaging we would have a lot of unnecessary surgeries because we would have no way to look into the body before the surgery.

Magnetic Resonance Imaging, or commonly known as MRI, is a technique used in medicine for producing images of tissues inside the body. It is an important diagnostic tool because it enables physicians to identify abnormal tissue without opening the body through surgery. MRI lets physicians see through bones and organs. MRI does not expose the patient to radiation, unlike tests that use X-rays. MRI provides an unparallel view inside the human body. It is the method of choice for the

Magnetic Resonance Imaging (MRI) produces images of organs and structures inside the body by using magnetic field and pulses of radiofrequency (RF) energy. An MRI machine consists of two powerful magnets that generate strong magnetic field when electricity is passed through a conductive field coil. Human body contains large amount of water molecules that are randomly arranged. Upon entering the machine, the hydrogen nuclei of the water molecules align in one direction. Then, a second RF pulse is applied in a series of quick pulses that cause the hydrogen nuclei to be out of spin alignment. When the RF pulse is switched off, the hydrogen nuclei realign themselves and relax by releasing RF signals, also known as free-induction decay (FID) response

As we have previously discussed one of the benefits to Radiography is that there are many modalities to further our career and knowledge which will further our success. Magnetic Resonance Imaging or “MRI” as we know it had always been something that intimidated me. The crazy amounts of physics involved deterred me from understanding the modality. However, after doing research and watching a few exams being done, it started to peak my interest. Before a patient undergoes an MRI, they must first be approved through insurance. Once the insurance gives the go, and a patient arrives they must fill out the pre-screening MRI form. This form asks multiple questions such as any previous eye injuries involving metal shavings

An MRI is an imaging technique used in the field of radiology. The acronym stands for Magnetic Resonance Imaging. The technique relies on the principles of atomic structure to function, namely the positive charge of the proton reacting to a magnetic field. An MRI is commonly used to assess organs of the torso area (such as the heart and liver), pelvic organs (such as the bladder and reproductive organs), the brain, the spine, lymph nodes, blood vessels and other body parts. Doctors can use an MRI to find tumors, cysts, diseases of the liver and other organs, cardiac problems, nervous system anomalies and many other internal issues of the body. MRI scans relate to the principles of atomic structure in a very interesting way. Our bodies are

Scanner - An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the scan.
