DEPARTMENT OF RADIOLOGY POLICY ON THE ADMINISTRATION

DEPARTMENT OF RADIOLOGY POLICY ON THE ADMINISTRATION OF IV ...DEPARTMENT OF RADIOLOGY POLICY ON THE ADMINISTRATION OF IV CONTRAST MEDIA Policy Intravenous contrast material is to be administered by a qualified physician or trained radiologic nurse. A radiologist or radiology resident/fellow will administer all other parenteral contrast material. The supervising physician will prescribe the nature, dose and rate of contrast administration. The patient’s risk status will be assessed prior to contrast administration, so as to determine the type, quantity and dose of contrast to be administered. Standard recommendations for

these injections will be available in the area where these procedures are performed. During and following the injection, the administering individual will remain with the patient to observe for possible reactions. Emergency equipment and emergency pharmaceuticals must be available. All individuals administering contrast must be trained in the emergency protocols as per Departmental Policy. A radiological technologist may prepare the contrast media and prepare the delivery unit (syringe, power injector, etc.). Consent Informed consent will be obtained by the requesting physician or the radiologist in the department. Prior to contrast administration the patient or guardian is required to sign an informed consent explicitly stating that the risks, benefits, and alternative choices have been thoroughly explained to, and understood by the patient or appropriate guardian. Consents are obtained by the designated physician in the department or by medical or surgical House staff. Registered nurses and Radiologic Technologists are permitted to witness consents. All personnel administering contrast are required to confirm the presence of a consent prior to injection Classifications Two choices are available: 1. Conventional contrast media 2. Low osmolality media (LOCM) Complications Iodinated intravenous contrast agents, used for radiologic procedures, possess a small risk of reactions, which can range in...

Massachusetts Institute of Technology. The authors wish to thank the Alfred P. Sloan Foundation for generous financial support, the two teleradiology firms in India for allowing us to study their organizations, and numerous radiologists and other healthcare professionals in India, Singapore, the United Kingdom, and the United States for helpful discussions. Many of these people asked that their names not be acknowledged. The people who we can acknowledge include Henry Aaron, Jane Adam, Nick Barr, Satish Kumar Bhargava, Adrian Dixon, Howard Forman, Richard Frank, Ari Goelman, Gordon Harris, Julian Le Grand, Barbara McNeil, Manoj Mohanan, Jonathan Sunshine, Katherine Swartz and Shih-Chang Wang. 1 Abstract: We discuss teleradiology and medical image reconstruction from the perspectives of both India and its client countries. Radiology is an “extreme” professional service with extensive usage of tacit rather than codified knowledge. The importance of tacit knowledge leads to long training periods, a limited global supply of radiologists and heavy government regulation, all of which are obstacles to a “flat world”. Computerization of low-end diagnostic radiology ultimately poses a bigger threat to the profession than offshoring. Keywords: offshoring, outsourcing, institutions, professional work, skills, technology 2 Introduction When people discuss the world’s new flatness, the conversation often...

Forensic radiology

Forensic radiologyReview article Forensic radiology 1 T KAHANA, PhD and 2 J HISS, MD 1 Israel National Police, Division of Identi¢cation and Forensic Science, Headquarters, Jerusalem, and 2 The L. Greenberg Institute of Forensic Medicine, 67 Ben Zvi Street, PO Box 49015,Tel-Aviv 61490, Israel Abstract. Imaging techniques are a powerful tool in forensic science. Medical examiners and forensic anthropologists are less versed in the ¢ner points of radiology than radiologists; nevertheless they are required to interpret ¢ndings from imaging studies

to further medico-legal investigations. The forensic investigator often should call upon the radiologist whose expertise might prove invaluable in forensic consultations.The radiologist should be aware of the importance of storing radio- graphs over prolonged periods of time and of e⁄cient record keeping methods, because various legal problems may require the radiographs for additional interpretation or for their presentation in court. Some of the main issues that might be encountered in forensic radiology are discussed in this review. The importance of radiographic techniques in clinical forensic medicine is widely recognized. Radiographs are taken on post-mortem examina- tions to locate foreign bodies or document frac- tures and other types of injuries. Radiological examinations play a signi¢cant role in diagnosing non-accidental injuries of children, in medical negligence and in establishing biological aging in disputed cases. Finally, in forensic anthropology and odontology the comparison of ante-mortem and post-mortem radiographs is one of the corner- stones of positive identi¢cation of human remains. The aim of this review is to cover the various uses of radiology within forensic medicine. Clinical radiologists and forensic experts should be aware of the responsibility incurred when o¡er- ing an expert testimony in a court of law. Some suggestions related to storage and record keeping of radiographs will be o¡ered, although regula- tions...

All rights reserved. introDUCtion The practice of radiology is wrestling with optimizing the use of high-cost imaging, spiraling costs, decreasing reimbursements, and its role in improving patient outcomes. With over 1 billion radiology exams performed each year in North America, imaging has nudged out pharmaceuticals as the fastest growing component of medical costs. 1 At a compound annual growth rate (CAGR) of 20%, the overall cost of diagnostic imaging is estimated at well over $100 billion annually in the United States alone. 2 Because the rate of innovation and de- mand for improved diagnostic testing show no signs of abatement, the appetite for providers and consumers in adopting the latest technology is likely to continue. As the industry experiences dramatic growth, radiology practices are feeling the effects of increased competition, diminished reimbursement rates and a slowing growth of referral net- works. In order to stay abreast of these ever-changing challenges, it is necessary to make more effective use of the data and technology that is available today. Improving services...

BASIC QUALITY CONTROL IN DIAGNOSTIC RADIOLOGY

BASIC QUALITY CONTROL IN DIAGNOSTIC RADIOLOGYAAPM REPORT No. 4 BASIC QUALITY CONTROL IN DIAGNOSTIC RADIOLOGY American Association of Physicists in Medicine FOREWORD This document, “Basic Quality Control in Diagnostic Radiology”, is the fourth in a series of AAPM reports. This document is designed to enable technologists working with the guidance and supervision of a medical physicist to set up a viable quality assurance program in diagnostic radiology with minimal expense. The AAPM, through its Diagnostic Radiology Committee, plans to issue additional documents detailing physicist/engineer level

test methods which utilize more sophisticated equipment. These additional tests will be suitable for installation and acceptance test- ing and for determining compliance with requirements of the Bureau of Radiological Health and state and local radiation control agencies. The American Association of Physicists in Medicine is organized, as one of its declared purposes, to prepare and to disseminate technical information in medical physics and related fields. In fulfillment of this purpose, the AAPM through a structure of Task Forces, Committees, and Councils prepares recommendations, policy and state-of-the art reviews in the form of reports. These reports cover topics which may be scientific, educational or professional in nature, and final approval of them is given by that Council of the Association charged with responsibility for the particular concerns of the report. The Publications Committee of the AAPM hopes that this report will effectively continue the record of published work previously reported by other scientific committees and so ably inaugurated by the previous Publications Committee.

A Pain in the Ear: The Radiology of Otalgia

A Pain in the Ear: The Radiology of Otalgiareferred to the ear from distant structures that receive sensory innervation from the same four cranial nerves as the ear itself: the upper and lower aerodigestive tracts, TMJs, teeth, salivary (middle ear) surface of the TM (7), the middle ear mucosa, and the upper eustachian tube (4).

Weissman, Departments of Radiology and Otolaryngology, Otalgia is ear pain. Ear disease causes pri- mary otalgia. Secondary (referred) otalgia is referred to the ear from disease in structures remote from the ear. Otalgia, especially referred otalgia, can be a diagnostic challenge. The radiologic approach to a patient with otalgia relies on the physical examination. If the otoscopic findings are abnormal, the computed tomographic (CT) or magnetic resonance (MR) study focuses on the temporal bone. (The ap- propriate radiologic study depends on the dis- ease.) The physical examination for ear pain includes the ear (auricle and temporal bone) and structures that are potential sources of re- ferred pain. Imaging studies can show clinically occult temporal bone disease as well as sources of referred pain in the nasopharynx, retrophar- ynx, paranasal sinuses and nasal cavity, tem- poromandibular joint (TMJ), parotid gland, oro- pharynx and oral cavity (including teeth), hypopharynx and larynx, thyroid gland, esoph- agus, and trachea. Tailoring a CT or MR study to evaluate primary or referred otalgia requires an understanding of the (admittedly complex) anatomy of ear pain. Sensory Innervation Briefly, sensation from...
