Ultrasound is a diagnostic method that uses high-intensity sound waves to produce the images of structures within the body. It serves as a valuable source of information for several purposes, including diagnosis of various diseases and monitoring the course of pregnancy. Ultrasound can also be used as an image guidance tool during certain medical procedures. The images generated by an ultrasound are known as sonogram. Ultrasound can be categorized into three main types, which includes pregnancy or prenatal ultrasound, diagnostic ultrasound, and ultrasound guidance for procedures. There are several procedures that need ultrasound guidance, such as guiding needle placement to sample fluid or tissue from joints, tendons, muscles, transplant organs, etc. Lesion localization procedures, embryo transfer for in vitro fertilization and nerve blocks are some other medical procedures that make the use of ultrasound guidance. Ultrasound is also used for the management of patients undergoing critical care. The diagnosis and assessment of various medical conditions such as pulmonary edema, pneumothorax and deep vein thrombosis can be done in a rapid manner through ultrasound. This book unravels the recent studies on ultrasound imaging. It strives to provide a fair idea about its applications in critical care. This book is appropriate for students seeking detailed information in this area as well as for experts.

Ultrasound refers to high frequency sound waves which are higher than the upper audible limit of human hearing. These sound waves are used in a variety of fields, such as diagnostic imaging, ultrasonic devices and non-destructive testing of structures and products. In clinical use, ultrasound is used to capture live images of internal structures of the body. The point of care ultra sound is the use of ultrasound in an emergency situation, for making decisions regarding immediate patient care. It is used to diagnose medical conditions and injuries, where diagnostic methods that are utilized conventionally would consume more time and increase the risk to the health of the patient. The point of care ultrasound is also helpful in monitoring the patient's response to the therapeutic interventions. This book provides significant information of point of care ultrasound to help develop a good understanding of this diagnostic method. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of medical imaging.

An ultrasound is an imaging test that uses sound waves to generate the images of various structures inside the body. Point of care ultrasound is the use of ultrasound for making immediate decisions regarding the patient's care in emergency situations. This application of ultrasound is used for evaluating the medical condition in settings like combat zone, emergency medicine, ambulance or critical care unit. Point of care ultrasound is used for diagnosing certain pathologic conditions or injuries quickly, where other diagnostic methods will consume more time and expose the patient to greater risk. It is used for monitoring and guiding resuscitation of terminally ill patients, simultaneously confirming the clinical diagnosis to guide procedural guidance and safety. Furthermore, it is also being utilized in code blue situations, where a person has lost all signs of life. This book explores all the important aspects of point of care ultrasound in the present day scenario. It consists of contributions made by international experts. This book will prove to be immensely beneficial to students and researchers interested in this area of medical ultrasound.

Ultrasound imaging is a clinical imaging technique that provides real-time, quantitative anatomical and physiological information in humans. It can serve both diagnostic and therapeutic functions. The diagnostic ultrasound is a non-invasive technique that uses sound waves to scan the structures or parts within the body. Ultrasound images can capture the movement of the internal organs, fetus and blood flow through the vessels inside the body. There are several medical applications of ultrasound, which include monitoring the development and health of the fetus during pregnancy. A Doppler ultrasound is used to assess the movement of blood to parts of body such as the heart, placenta and testes. Therapeutic ultrasound can be used to alleviate pain from the spread of cancer into the bones (bone metastases). Some other applications of ultrasound imaging include treatment of uterine fibroids and prostate surgery. Various studies that are constantly contributing towards advancing technologies and evolution of this field have been examined in detail within this book. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of ultrasound imaging. The book will provide comprehensive knowledge to the readers.

Diagnostic ultrasound imaging is a type of imaging technique used to view the internal parts or structures of the body. It is a non-invasive diagnostic technique that examines body parts for detecting any kind of damage or problems with functioning. In the process of diagnostic ultrasound, a transducer is placed on the skin, vagina or rectum. There are different types of diagnostic ultrasounds including abdominal ultrasound, renal ultrasound, breast ultrasound, Doppler ultrasound, pelvic ultrasound, transvaginal ultrasound, thyroid ultrasound, and transrectal ultrasound. Renal ultrasound is an ultrasound used to gain information about the location, size and shape of the kidneys. It can also be used to assess information about related structures like ureters and bladder. The conditions such as cysts, tumors, and infections inside and around the kidneys are diagnosed with the help of renal ultrasound. Doppler ultrasound is used to analyze the flow of fluids like blood in the body. This book contains some path-breaking studies in the field of diagnostic ultrasound imaging. With state-of-the-art inputs by acclaimed experts of this field, it targets students and professionals associated with this field.

Radiology and ultrasound are the primary diagnostic imaging techniques available to the veterinarian

Ultrasound is a method of diagnostic imaging that uses high-frequency sound waves to produce images of structures within the body. This method involves the application of a thin layer of gel on the skin, which helps the transducer in transmitting ultrasound waves across the body. This device is placed directly on the skin, vagina or rectum to generate images through wave reflection. In this imaging method, sound travels through fluids and soft tissue which echoes back from denser surfaces for creating an image. Some common techniques used for ultrasound imaging are bone sonometry, abdominal ultrasound, breast ultrasound, echocardiogram, ophthalmic ultrasound, etc. Ultrasound guided biopsies are performed to collect a sample of tissue. Furthermore, it can also be used in the field of anesthesiology for guiding needle placement. This book discusses the clinical approach to ultrasound. It provides comprehensive insights into this area of diagnostic imaging. The book will serve as an invaluable resource for students and professionals.

In the diagnosis and evaluation of musculoskeletal (msk) diseases such inflammatory and non-inflammatory joint diseases, high resolution musculoskeletal ultrasound (hrMSUS or MSUS) is a superb, precise, and validated method.Many soft-tissue structures can be seen using high resolution musculoskeletal ultrasonography, and depending on the tissue under investigation, msus can also identify a variety of pathologic alterations employing mostly linear scan probes with frequencies ranging from 5 MHz to 24 MHz (up to 70 MHz when examining entheses, nails or the skin).Msk structures are assessed dynamically in real-time and static with the advantage of a multiplanar view.Msus is a helpful instrument for directed interventions at the msk system as well.This method has some limitations, including limited acoustic windows, difficulty detecting diseases in deep or large joints, a small field of vision, and a significant operator dependence.Attending theoretical and practical seminars, as well as individual research using books, websites, or social media, all qualify as training.Consolidating msus knowledge requires the use of high-quality ultrasound equipment and the performance of supervised normal and abnormal msus examinations throughout a training phase.The first focus of this textbook and atlas is to demonstrate a standardized ultrasound examination of the shoulder enhanced with basic anatomical (MRI-, CT-Scans; cadaver models) and arthroscopic images. The second focus is a thorough pictorial atlas of selected basic and advanced ultrasound pathologies.Giorgio TamborriniBasel, 2023
