Maggots are usually associated as pests, but now they can save lives! Well, I’m not referring to the real ones. They are robotic maggots! In a few years, these manufactured pests will be able to help neurosurgeons. They can help save patients facing brain tumors and will change the outlook of surgery. Robots won’t replace humans, but they can improve our abilities. Technology is being more and more integrated in the medical field. Robots can have their own specialties depending on what procedure…

father of MRI is Raymond Damadian, who received a Nobel Prize in 1952. (Reference #1) During its beginnings, MRI was used for chemical and physical analysis only, later in 1977 the medical history saw the first MRI examination on humans. Magnetic resonance imaging (MRI) is the result of a precise image of organs and tissues throughout the body, where…

obtained in 2014 by Chuang et al. (frontal lobes vs parietal lobes) most probably result from using different cognitive tasks in the MRI scanner (SCWT vs the Flanker Task). It is significant, however, that the results obtained with the magnetic resonance correspond to the results of the neuropsychological examination. The asymmetry of inhibitory processes (which are needed for correct executive control) is reflected in poor performance in neuropsychological tests. Verbal perseverations, both…

MRI is a unique medical practice among other imaging methods because, unlike radiographs for example x-rays and ct scans and even radioisotope studies it does not use ionising radiation to create an image of the body this is good because if it does not use ionising radiation it will not have the effects that the radiation causes to the human body. But instead of using other means such as ultrasound to create an image it uses strong magnets and radio waves to create detailed digital images of the…

CHAPTER ONE 1.0 INTRODUCTION 1.1 Background of the Study Ultrasonography is an excellent modality for examining abdominal structures including the location and dimensions of canine kidneys (Remichi et al., 2014). It involves a non-invasive procedure for examination of kidney diseases (Sampaio and Araujo, 2002) and offers advantages over radiography as there are no side effects of radiation and contrast agents (Nyland et al., 1995). Canine kidneys are located in the retroperitoneal region of the…

For the purpose of this paper, and a full understanding of the topic discussed, immerse yourself in these circumstances, as if you are the patient. You are lying in a hospital bed, unable to move, wanting to talk to your mom as she talks by your side, but unable to speak. You listen to the nurse and doctor speak to your family as if you are not there, as if you cannot hear or understand each word. You are angry, you are frustrated, and you can't even make a sound. You are only able to exist…

diagnostic purposes. The diagnosis from a radiographer’s image can affect, determine the treatment and care of a healthcare team. Wide ranges of imaging methods are used these include Ultrasound, X-ray, Fluoroscopy, Computed Tomography, Magnetic Resonance Imaging. Ranges of dyes or contrast agents are sometimes used to show…

Measuring Brain Activity to Reconstruct Visual Experiences The principle of perpetual evidence states that brain activity is not random, and that the processes we use in mental visualizations are used in visual perception as well. The firing of neurons that occurs when one imagines shooting a free throw are the same neurons that fire when actually doing so. The fact that brain activity is complex and calculated has helped scientists see how the brain functions, and what areas are associated with…

less serious, it could come for once and never come again. For these reasons, diagnosing Multiple Sclerosis (MS) is not straightforward, however, there are several tests that could determine whether you have it or not. The first one is the Magnetic Resonance Imaging (MRI). MRI is a diagnosing tool that visualize the brain, spinal cord, or other parts of the body in a most sensitive non-invasive way.2 MRI is particularly useful in detecting central nervous system demyelination (removal of the…

Interventional radiology is considered a specialized modality of radiology that deals mostly with invasive image-guided procedures. With advances in technology, interventional procedures can be performed on several areas of the body with success in conjunction with using live x-rays during exams. Cerebral aneurysms often can be in susceptible areas of the brain, and usually, are considered somewhat high risk in nature. The use of endovascular coiling can prove to not only be successful, but…
