X-ray computed tomography

it has been widely-used ever since. The first use of nuclear energy in the medical field is for medical imaging which is a way of creating visual representation of what is going on in our body. Medical imaging began when Wilhem Rontgen discovered x-ray in 1895. However, at that time, the dangers of radiation was not known yet. Fast forward about 20 years later, contrast agents which are harmless to the body were used to visualize bile ducts, gall bladders and our digestive systems. By the 1950s,…

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…

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…

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…

An MRI scanner or a magnetic resonance imaging is a common apparatus used within hospitals which uses a scanning technique to show detailed images of the inside of a human body. There are two ways which an MRI scanner takes images of the human body. The two ways are the use of a strong magnetic field and the use of radio waves. There are two ways which MRI scanners work and the first is by hydrogen atoms. How this links within the human body is by the main link of hydrogen protons which are…

between blood vessels, necrotic, and healthy tissue (Pagana & Pagana, 2014). Although this method could be helpful in diagnosing acute appendicitis for the patient, there is greater support towards healthcare professionals utilizing computerized tomography (CT) scans for diagnosis. Sources such as Rodgers and Wilson (2017)…

The trauma radiographer should take the important responsible in radiation protection of the patient, member of the trauma team, and the radiographer himself or herself. Member of the trauma team cannot leave the patient in critical situation while imaging procedure are being performed. The unnecessary radiation exposure should be avoid and the trauma radiographer must unsure the team member are protected. In general radiography, common practices should minimal the radiation exposure include…
