Ultrasound Q&A Review for the Boards
Ultrasound Q&A provides invaluable prep material for board exams! Ultrasound Q&A Review for the Boards by esteemed radiologist and educator Adrian Dawkins and an impressive array of authors, delivers a robust test prep. Employing a self-evaluation approach, the book presents fundamental and practice-oriented concepts in ultrasound. The overall layout mirrors the ABR board exams, with ultrasound images presented in a clinical framework followed by board-format multiple-choice questions. Chapters are generally organized by organ systems and encompass all major areas. The text starts with two chapters covering the first and second trimesters of pregnancy. Subsequent chapters encompass pediatric, renal, hepatobiliary, musculoskeletal, breast, neck, and scrotal ultrasound. The final two chapters on miscellaneous topics and physics ensure a more comprehensive review. Key Features * Easy-to-follow cases reinforce common ultrasound concepts, aiding in retention * Practical questions and answers inspired by everyday practice include explanations for both the correct and incorrect answers, enhancing comprehension and knowledge * References at the end of each chapter provide readers with resources for further exploration This book provides an essential review for radiology trainees prepping for initial board certification and sonographers preparing for the boards.

Fixing the Image
Traces affective and aesthetic dimensions of medical imaging
technologies
Introduced in Phnom Penh around 1990, at the twilight of
socialism and after two decades of conflict and upheaval,
ultrasound took root in humanitarian and then privatized medicine.
Services have since multiplied, promising diagnostic information
and better prenatal and general health care. In Fixing the Image
Jenna Grant draws on years of ethnographic and archival research to
theorize the force and appeal of medical imaging in the urban
landscape of Phnom Penh. Set within long genealogies of technology
as tool of postcolonial modernity, and vision as central to skilled
diagnosis in medicine and Theravada Buddhism, ultrasound offers
stabilizing knowledge and elicits desire and pleasure, particularly
for pregnant women. Grant offers the concept of \"fixing\"-which
invokes repair, stabilization, and a dose of something to which one
is addicted-to illuminate how ultrasound is entangled with
practices of care and neglect across different domains. Fixing the
Image thus provides a method for studying technological practice in
terms of specific materialities and capacities of technologies-in
this case, image production and the permeability of the
body-illuminating how images are a material form of engagement
between patients, between patients and their doctors, and between
patients and their bodies.

The Public Life of the Fetal Sonogram
In The Public Life of the Fetal Sonogram, medical anthropologist Janelle S. Taylor analyzes the full sociocultural context of ultrasound technology and imagery. Drawing upon ethnographic research both within and beyond the medical setting, Taylor shows how ultrasound has entered into public consumer culture in the United States. The book documents and critically analyzes societal uses for ultrasound such as nondiagnostic \"keepsake\" ultrasound businesses that foster a new consumer market for these blurry, monochromatic images of eagerly awaited babies, and anti-abortion clinics that use ultrasound in an attempt to make women bond with the fetuses they carry, inciting a pro-life state of mind.
This book offers much-needed critical awareness of the less easily recognized ways in which ultrasound technology is profoundly social and political in the United States today.

Ultrasound Elastography for Biomedical Applications and Medicine
Ultrasound Elastography for Biomedical Applications and MedicineIvan Z. Nenadic, Matthew W. Urban, James F. Greenleaf, Mayo Clinic Ultrasound Research Laboratory, Mayo Clinic College of Medicine, USAJean-Luc Gennisson, Miguel Bernal, Mickael Tanter, Institut Langevin – Ondes et Images, ESPCI ParisTech CNRS, FranceCovers all major developments and techniques of Ultrasound Elastography and biomedical applicationsThe field of ultrasound elastography has developed various techniques with the potential to diagnose and track the progression of diseases such as breast and thyroid cancer, liver and kidney fibrosis, congestive heart failure, and atherosclerosis. Having emerged in the last decade, ultrasound elastography is a medical imaging modality that can noninvasively measure and map the elastic and viscous properties of soft tissues.Ultrasound Elastography for Biomedical Applications and Medicine covers the basic physics of ultrasound wave propagation and the interaction of ultrasound with various media. The book introduces tissue elastography, covers the history of the field, details the various methods that have been developed by research groups across the world, and describes its novel applications, particularly in shear wave elastography.Key features:Covers all major developments and techniques of ultrasound elastography and biomedical applications.Contributions from the pioneers of the field secure the most complete coverage of ultrasound elastography available.The book is essential reading for researchers and engineers working in ultrasound and elastography, as well as biomedical engineering students and those working in the field of biomechanics.

Manual of Emergency and Critical Care Ultrasound
The use of ultrasound has revolutionized the way in which many acute injuries and conditions are managed in emergency department and critical care areas in hospitals. Emergency departments nationwide are outfitted with ultrasound equipment, allowing acute conditions to be diagnosed within critical seconds. This book is a practical and concise introduction to bedside emergency ultrasound for all critical care physicians. It covers the full spectrum of conditions diagnosed via this modality, both for guiding invasive procedures as well as diagnosis in critical-care settings. It introduces the major applications for emergency ultrasound by using focused diagnostic questions and teaching the image-acquisition skills needed to answer these questions. Images of positive and negative findings for each application (FAST, ECHO, etc.) are presented, as well as scanning tips for improved image quality. Each section also contains a review of the literature supporting each application.

P43 Diaphragmatic ultrasound as a marker of clinical status and early readmissions after acute exacerbations of COPD: preliminary results from a prospective cohort study
IntroductionThe management of acute exacerbation of COPD (AECOPD) is complicated by the lack of a specific biomarker related to clinical course and readmission/treatment failure risk. As AECOPD are characterized by an acute worsening of lung hyperinflation and increased respiratory work, which can lead to diaphragm weakness and/or fatigue, we hypothesized that the serial monitoring of diaphragm function during an AECOPD could provide clinically relevant information on the clinical status of patients and their treatment failure risk.MethodsPatients with AECOPD requiring hospitalization in our center were prospectively recruited. Diaphragm thickening fraction (reported as the ratio of tidal to maximal thickening fractions of the diaphragm – TF%max) was measured using ultrasonography within 24h of admission and within 24h of discharge. The difference in TF%max value between admission and discharge was reported as ΔTF. In addition to clinical and demographic characteristics, National Early Warning Score (NEWS), COPD Assessment Test (CAT) and blood gases were retrieved at the time of admission. Treatment failure was defined as a readmission to the emergency department/hospital <30 days after discharge.Results18 patients were recruited [mean (±standard deviation) age 74±7 years, FEV139±17%, residual volume 153±69% and CAT score 26±6]. Mean TF%max decreased from 54±20% on admission to 43±19% at discharge (p=0.06). Mean ΔTF was -10±50%. 5 patients (28%) were readmitted within 30 days. In these patients, TF%max at the time of discharge and the change in TF%max during hospitalization were significantly different than in those without readmission (65±7 vs 35±16%, p=0.001 and 30±66 vs -27±35%, p=0.02, respectively) (figure 1). ΔTF was significantly correlated to length of hospital stay (rho=0.49, p=0.04), but TF%max, NEWS, CAT score and pCO2 measured on admission were not (all p>0.05).Abstract P43 Figure 1ConclusionsTF%max, measured using ultrasonography, is responsive to clinical evolution during episodes of AECOPD, and may be able to predict the risk of early readmission. Further data is required to better delineate the role of diaphragm ultrasound in this setting and to identify clinically relevant threshold values associated with negative outcomes.
