How Does Medical Imaging Work?

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).

Medical ultrasound (also known as diagnostic sonography or ultrasonography) is an diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs. The aim of often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used.

Radiology (70010–79999)- radiology comprises modalities (methods of applying a therapeutic/physical treatment) that use distinct technology and equipment to obtain images. Radiological modalities include plain radiography, also called X-ray, ultrasound (US), computed tomography (CT), nuclear medicine (NM), positron emission tomography (PET), and magnetic resonance imaging (MRI).

Even in the operating room visual technology is used as both surveillance and an aid. In addition to helping doctor, Joyce also brings up the point on how an MRI illuminates a doctor's fear of litigation. Lawsuits are common to medical practices and the fear of litigation is always present. The cultural trend of scepticism and the need to "cover your ass" makes the use of MRIs much more common. With an image, a doctor could argue how their interpretation was right or wrong and it is easier than explaining what he/she observed.

There is a lot of history relating to ultrasound or another name is sonography. It has come very far for the uses in not only medical situations but other technological situations. Ultrasound has been seen to dates back to the 1700’s. The first inventor known to study ultrasound is Lazzaro Spallanzani in 1794. He was a physiologist to first study ultrasound physics by using bats. Bats use echolocation, which are sound waves that travel in the air till they hit an object and bounce back to the bat so it can in a sense see what is around him by knowing how long the wave took to get back. Ultrasound works similarly to bats echolocation. It uses high frequency sound waves that capture live images from inside the body. This works like how a bat can see with soundwaves but be almost blind. The next person Karl Dussik, physicist was the first doctor to use ultrasound as an instrument for diagnosis called it Hyperphongraphy. They used this to try and locate brain tumors with one transducer on side of the skull

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

Healthcare has evolved tremendously over the last few decades. Technology, being one of the biggest impacts has reached new heights and has advanced our learning and knowledge to places unimaginable. Many different modalities take place in the health field to ensure the greatest treatment for everyone with improving outcomes. Three modalities that have enhanced and have taken special roles in 3-D imaging include, CT scans, MRI, and Ultrasound; each with their own advantages and disadvantages. These modalities all require training, are cost effective, and take a specific amount of time to obtain all the necessary information. These same modalities have different traits regarding the use of radiation, contrast, evidence

In the field of radiologist technologist you have number of imagines to perform. One type of imaging is x-rays, in order to get a clear picture you must position the bone in a correct position. You need to get the correct angle the physician ordered so you can develop and come up with the correct diagnoses. A computer tomography better known as a CT scans you used by injecting a radioactive solution into a

Escalating advancements in medical technology has been very beneficial in diagnosing patients and providing patients with the best care possible. The use of technology in medicine has saved, extended, and improved lives. Modern day equipment in the medical field is nothing short of remarkable. The merger of technology and medicine has increased quality of life and maintained health. For example, technology has introduced equipment and improved medical research. A sonographer uses a transducer, which involves high frequency sound waves and as they reach internal organs, they are displayed on a screen as an image. This device is simple yet so crucial in ultrasounds because they diagnose the causes of infections, heart disease, blood clots

Diagnostic Imaging is the career that I am currently in school for and is very interesting to me as well as helpful to the patients. X-Ray has been around since its discovery in November of 1895. It allows people in the medical profession to see inside the human body without having to perform invasive surgery that could be harmful to patients without knowing what is wrong with

In today’s generation technology is the key point in all of our lives. With all those new technological inventions a huge percent of those inventions refer to the medical field.

Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into the body. And because the tissue interference's reflect sound, doctors are able to produce, by use of a computer, a photograph or moving image on a television. Ultrasound has many application uses on the body, but is more commonly used in examinations of the fetus during pregnancy, because use of radiation may affect the outcome of the baby. Some other practices for ultrasound include examination of the arteries, heart, pancreas, urinary system, ovaries, brain, and spinal cord. And because sound travels well through fluids it is a very useful technique for diagnosing cysts( which are filled with fluid), and fluid filled structures such as the bladder. And since sound is absorbed by air and bone it is impossible to use a ultrasound on bones or lungs.

• MRI (magnetic resonance imaging) is a diagnostic test that uses large magnets, radio frequencies, and a computer to make images of organs and structures within the body. This test outlines the extent of the tumor within the bone and joint and the relationship of the tumor to the muscles, nerves and blood vessels.

MRI technology is a useful technique in the medical industry, there are many advantages to its use and for the most part the disadvantages of its use are minimal. They are great because they provide very detailed diagnostic pictures of most of the important organs and tissues in one’s body. They are also capable of showing unique information that other tests are unable to show. They are generally painless. Furthermore, they do not use radiation and are therefore suitable for use in children and pregnant women. Although there are many good attributes to MRI’s, there are still disadvantages to its use. For one, many people are claustrophobic and being in an MRI can become very uncomfortable for them. In addition, the MRI makes a tremendous amount of noise. Often patients are given earplugs or stereo headphones in attempt to muffle the noise.

Medical or Diagnostic Imaging refers to the various techniques that can be used to see inside the human body. Its non-invasive nature means that the body does not have to be opened up surgically for medical practitioners to view the organs anatomically. In clinical settings, it can be used to aid in the diagnosis or treatment of different ailments. Many kinds of medical imaging techniques have already been developed, each with their own advantages
