Achieve the most accurate imaging diagnosis for pediatric radiology.

"Differential Diagnosis in Pediatric Imaging"offers the most up-to-date knowledge of pediatric imaging diagnostic techniques. It provides imagers, clinicians and their trainees with simple methods to evaluate both frequently and rarely seen diseases and disorders, and suggests differential diagnoses fully taking into account clinical findings. In addition, the text provides how-to tips for identifying normal images - saving time and helping to avoid common misinterpretations.

Readers are guided through a comprehensive, easy-to-navigate radiological library of pediatric disorders, which are divided by organ system. Sections include the head and neck, chest, musculoskeletal, urogenital and the digestive tract, and are complemented by a thorough review of normal values. Each chapter discusses the imaging findings and different diagnostic possibilities, while mirroring clinical situations encountered in daily practice.

Features: Easy-to-read tables highlight important findings and clinical clues to help identify diagnoses at a glance 1,500 high-quality images cover all major childhood disordersA comprehensive chapter on normal values and measurements

Written by an international group of expert authors, this text is the foremost guide to the expanding specialty of pediatric radiology. Radiologists and residents in radiology can use this text as reference for daily practice and in preparation for exams.

This report provides reviews of information on the transit of materials through the alimentary tract and on radionuclide retention and absorption. It considers data on health effects, principally in order to specify the target cells for cancer induction within the mucosal lining of the tract and to justify approaches taken to dose averaging within regions. Comparisons are made between doses calculated using the HATM and the Publication 30 model for examples of radionuclide ingestion for which absorption is assumed to occur in the small intestine alone. Examples are also given of the effect on doses of considering absorption from other regions and the effect of possible retention in the alimentary tract. This report also considers uncertainties in model assumptions and their effect on doses, including alimentary tract dimensions, transit times, radionuclide absorption values, and the location of targets for cancer induction.

This book gives a broad treatment of the subject which will include 1)the optics, science, and physics needed to understand the technology 2)a description of applications with a critical look at how the technology will successfully address actual clinical need, and 3) a discussion of delivery of OCT to the patient, FDA approval and comparisons with available competing technologies.
The required mathematical rigor will be present where needed but be presented in such a way that it will not prevent non-scientists and non-engineers from gaining a basic understanding of OCT and the applications as well as the issues of bringing the technology to the market.
* Optical Coherence Tomography is a new medical high-resolution imaging technology which offers distinct advantages over current medical imaging technologies and is attracting a large number of researchers.
* Provides non-scientists and non-engineers basic understanding of Optical Coherence Tomography applications and issues.

This report considers the evidence relating to cancer risk associated with exposure to low doses of low-LET radiation, and particularly doses below current recommended limits for protection of radiation workers and the general public. It looks at the possibility of establishing a universal threshold dose below which there is no risk of radiation-related cancer. The focus is on evidence regarding linearity of dose response for all cancers considered as a group, but not necessarily individually, at low doses (the so-called linear, no-threshold (LNT) hypothesis). The report concludes that while existence of a low-dose threshold does not seem unlikely for radiation-related cancers, it does not favor the existence of a universal threshold. The LNT hypothesis, combined with an uncertain dose and dose rate effectiveness factor (DDREF) for extrapolation from high doses, remains a prudent basis for radiation protection at low doses and low dose rates.

First published in 1939, Clark's Positioning in Radiography is the definitive text on patient positioning for the diagnostic radiography student and practitioner. This fully-revised 12th edition will ensure that the title retains its pre-eminence in the field, with hundreds of new positioning photographs and brand new explanatory line diagrams, a clearly defined and easy-to-follow structure, and international applicability. The book presents the essentials of radiographic techniques in as practical a way as possible, avoiding unnecessary technical complexity and ensuring that the student and practitioner can find quickly the information that they require regarding a particular position. The experienced author team, expanded for this revision, understand that there is no substitute for a good understanding of basic skills in patient positioning and an accurate knowledge of anatomy to ensure good radiographic practice. All the standard positioning is included in this single volume, accompanied by supplementary positions where relevant and illustrations of pathology where appropriate. Common errors in positioning are also included.

In the present report, ICRP provides information on radiation doses to the infant due to intakes of radionuclides in maternal milk. As in Publication 88 (ICRP, 2001) on doses to the embryo and fetus following intakes of radionuclides by the mother, intakes by female members of the public and female workers are addressed. Acute and chronic intakes are considered at various times before and during pregnancy as well as during the period of breastfeeding. Dose coefficients per unit intake by the mother (Sv/Bq) are given for the selected radionuclides of the same 31 elements for which age-specific biokinetic models were given in Publications 56, 67, 69, and 71. For these elements, doses were calculated for the most radiologically significant natural or artificial radionuclides that might be released into the environment due to various human activities. Dose coefficients are also given in this report for radionuclides of an additional four elements: sodium, magnesium, phosphorus, and potassium.

The topography of the normal lymphatic pathways is comprehensively presented here in axial CT scans. Schematic figures corresponding to each scan make it easy to understand the topography. The main chapters cover the head and neck, the thorax, the abdomen and the pelvis. A short introduction to the lymphatic drainage system is also given. The additional description of the lymphatic nodes for every organ enables the reader to analyze CT scans systematically for enlarged lymph nodes. This atlas contains information vital for radiographers, who must determine how normal and pathologically enlarged lymph nodes are connected with certain lymph node groups in order to correctly stage tumors and their metastases. For radiotherapists, knowledge of the exact topography of a lymphatic drainage region will help to determine the best treatment volume.
