Resonance

Like any other cells in the body, when neurons are activated they consume glucose and oxygen to fuel their activity and they produce metabolic waste. According to Sadock, Sadock, and Ruiz (2015), a functional magnetic resonance imaging (fMRI) device works from this principal by using high magnetic fields and radio frequencies to indicate activity. The fMRI helps the medical professional to peer into brain activity, not by measuring brain activity directly, but by observing the flux of oxygen…

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…

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…

Ultrasound (US) and MRI are commonly used in the clinical setting to confirm the presence and location of tendon thickening or other structural change and associated findings (Scott et al., 2013). However, although their clinical utility, both US and MRI are subject to artefacts and may reveal poor interobserver and intraobserver reliability. In comparison with MRI, ultrasound has the accuracy and sensitivity of US (0.63–0.83 and 0.68–0.87, respectively) and MRI (0.68–0.70 and 0.50–0.57,…

Alternative Imaging for MRI in MS MRI is a great tool for medical imaging and widely used for Multiple Sclerosis (MS), but it has some limitations in lacking specificity1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) have the potential to address issues not resolved by current MRI techniques. TMS is a non-invasive technique used for monitoring the central nervous system (CNS) activity and response in a pain-tolerated manner. It…

Neuroscientists have available to them several techniques to understand the relationship between brain and behaviour. However, the lesion method is the best one to establish that an area is involved in a certain task. Lesion studies have been beneficial in identifying these relationships based on examining brain damaged people. This paper will argue the important contributions the lesion method has made to neuroscience while exposing the problems associated with the functional brain imaging…

Patients must first receive a referral from their doctor 2. Patients or doctor’s assistant contact the MRI scheduling department to get appointment 3. Receptionist at scheduling department writes the patient’s name and type of procedure on the daily schedule form (8 time slots, each for a one-hour increment) 4. Patients check in with the receptionist upon arrival and wait for the MR technologist to escort them to the MR machine in the magnet room 5. Patients are questioned about possible…

Mammograms, ultrasounds, x-rays, and MRIs have helped women with breast cancer since 1895 (x-ray) 1956 (ultrasound) 1977 (MRI), and 1992 (mammogram). They have all been very beneficial to women. Breast cancer is the most common type of cancer in women. About one of three cancers are diagnosed. Cancer is a group of diseases that cause cells in the body to change and grow out of control. Most cancers will form a lump or mass in the breast, which is called a tumor. It is named after a part of the…

Advantages of Endoscopic Septoplasty Endoscopic Septoplasty is associated with several advantages over the traditional one. It has many benefits such as magnification, suboptimal view of middle turbinate, better illumination and visualization. Separation of collagenous fibers connecting the perichondrium and periostium to underlying bone and cartilage is made visible with endoscope during surgical dissection. Mucosal disruptions are recognized immediately, and their size may be controlled using…

Purpose: The purpose of this memorandum is to present an analysis of the person(s) who would read this report. This report was created as one of the projects for a Writing for Technical Professional class. The goal of this project was to analyze the success of a medical innovation. My chosen topic was Focused Ultra Sound that enhance the drug delivery for treatment of CNS diseases. Audience Description: While writing this technical report, I imagined 2 types of people who would read it. The…
