Lasik surgery is the most common type of refractive surgery. The aimed result of the surgery is to refract light rays on the retina without damaging the surrounding cellular cells. Lasik surgery is a procedure that was developed to correct the vision problems of Nearsightedness, Long-sightedness and Astigmatism. Nearsightedness (myopia) is when you can see nearby objects clearly, but distant objects seem blurry. Long-sightedness (hyperopia) is when you can see distant objects clearly, but nearby…

Peripheral artery disease (PAD), also known as arterial occlusive disease, is the obstruction or narrowing of aortic passages--including lumen and its major branches. This blockage interrupts blood flow, usually to the feet and legs. The prognosis will vary depending on the occlusion's site. The symptoms vary depending on the location of the occlusion. For example: in femoral arteries, having pain in the feet, no pulse in ankles and feet, and pallor or coolness in legs are symptoms.…

As a child, I was clueless as to what I wanted to be when I got older. I am the first person in my family to attend college, so I was never around anyone who had any type of education for their occupation. It was not until high school I decided I wanted to pursue the medical field since I have always had a strong notion to help those that are in need. Soon after a coworker of mine suggested the radiologic technology program at Roane State Community College. I began doing research on radiography…

Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when Miller…

medicine that combines the expertise of a radiologist together with the knowledge of therapeutic intervention using advanced techniques using a range of imaging guidance modalities such as X-ray fluoroscopy, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to accurately treat a medical condition. By the same token, Baum and Baum (2014, p. S76) implies that using the same diagnostic imaging tools that transformed medicine also assist the physician by applying…

this study correlate violenec to a certain part of the brain, but it also introduced the theory that the brains of men and women are different. Unlike a PET scan, an MRI and fMRI (functional magnetic resonance imaging) scan only shows the brain at the time when the image was taken. An MRI uses a strong magnetic field and radio waves to create images, not only of the brain, but of the whole body as well. The difference between an MRI and fMRI is that the fMRI used blood flow to detect brain…

The development of the MRI (Magnetic Resonance Image) machine has changed the medical world for the better. One of the first points about the MRI is that it was created by Professor Raymond Damadian in 1977. The first time the MRI machine was used, it took a total of five hours to do the whole scan. Also, the first MRI machine ever used is now in the Smithsonian Institute, and was nicknamed the “Indomitable.” Many people think they know what an MRI machine does, but most of the time they are…

imaging process to detect and then treat according to the specific disease. In the reference of the medical theory, the radiology is a field that interprets and medicates the diseases utilizing the imaging technologies, such as X-ray, ultrasound, MRI (magnetic resonance imaging), computed tomography (CT), nuclear medicine, mammograms, and positron emission tomography (PET) to view the internal organs of the human body and identify the abnormalities. Among these, some like X-rays and mammograms…

Have you ever wondered what the point of sleep was? Or, how we dream? A lot of scientists have researched and tried to determine why we sleep, but a true answer has never been concluded, but a strong theory has stated that us as humans may have evolved from animals that would sleep to put their body in a resting state, to keep them away from harm and to keep their body at a well-rounded temperature throughout the night. All mammals sleep, including marine animals such a platypus and a whale.…

Computed tomography (CT) scanning technology was discovered in 1972 and revolutionized the world of neuroimaging (Sadock, Sadock, & Ruiz, 2014). The CT scan was the first technique to allow the imaging of brain tissue in living patients (Sadock, Sadock, & Ruiz, 2014). During a CT scan, a patient lies on a flat surface, which incrementally moves through what is referred to as a gantry (Sadock, Sadock, & Ruiz, 2014). A gantry is a round shaped structure that contains a motorized x-ray source…
