The Discovery of Magnets by Santiago Webb We use magnets every day without knowing it; it might be fridge magnets, cabinet latches, speakers and other electronic devices. Magnets are used in many different fields such as in medicine, education, science, and just for fun. For example in medicine, magnetic resonance imaging (MRI) uses very strong magnets and radio waves to show doctors inside the human body. In science, magnets can help store information on computers; they are also…

This case study is in relation to a 21-year-old male adult, Danny who suffers from Chron’s Disease. Danny currently is a fourth-year student at York University majoring in Sociology. I know Danny through my younger brother, Danny is one of his closest friends. Chron’s Disease is an autoimmune disorder that targets your intestines and restricts the digestive process. Danny’s body does not absorb many nutrients due to ulcers that are lining his intestine. Regarding Danny’s Chron’s Disease, when…

Radiology (n.d.), Interventional Radiology is a novel field of 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…

important to understand the concept of interventional radiology, along with the radiation protection that follows it. According to Kessel (2013:1), interventional radiology is a special technique that exercises the use of radiological images, such as x-ray fluoroscopy, to accurately diagnose and treat. Interventional radiology often deals with vascular and non-vascular procedures, with vascular procedures being related to or supplied with blood vessels as defined by the Oxford Dictionary…

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…

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 (Sadock, Sadock, & Ruiz, 2014). This x-ray source rotates around the patient several times to obtain axial images at each degree around an individual’s head (Sadock, Sadock, & Ruiz, 2014). At each angle, the specific amount of radiation that is not absorbed…

This radiographic technique is used to give information about the position and shape of wisdom teeth roots and its nearby structures. • 3D CT (Computed tomography). A 3D computed tomography is more precise than the standard dimensional x-ray because it involves obtaining the exact position of your wisdom teeth as well as allows you and the dentist to see what is inside of it. Looking out for nerve damage Aside from understanding when should wisdom teeth be removed, it is also important…

September -The 30-ton rock, named after the town, was discovered on September 10 and dug up by excavation team which was shocked by its massive size.The original asteroid was estimated to have weighed about 600 tons and entered Earth's atmosphere at 14,000 kilometres per hour, where it broke up into a shower of smaller meteorites, according to Scientific American. August -Stanford lled a research shows that they were emerging in the memory technology, based on a new class of semiconductor…

MRI stands for Magnetic Resonance Imaging. Dictionary.com defines it as a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body. From my own prior knowledge, Magnetic Resonance Imaging is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within the human body. The idea for Magnetic Resonance Imaging was initially conceived by Damadian in 1971 after he recognized…

discovered x-rays. X-rays have evolved drastically over the past 120 years and there have been many new discoveries that are used to this day in diagnostic medicine. Some of the different modalities in medical imaging have also been very helpful when studying art and archeology. Both x-rays and CT’s are used to look at art to confirm its authenticity, archeology for the study of mummies, and also archeology to exam the charred scrolls at Herculaneum and pottery. Over the years, x-ray…
