It is also used for vascular access such as central venous cannulation and difficult arterial cannulation. Transcranial Doppler is frequently used by neuro-anesthesiologists for obtaining information about flow-velocity in the basal cerebral vessels. Angiology vascular [ edit ] Intravascular ultrasound image of a coronary artery left , with color-coding on the right, delineating the lumen yellow , external elastic membrane blue and the atherosclerotic plaque burden green.
Further information: Doppler ultrasonography and Intravascular ultrasound In angiology or vascular medicine, duplex ultrasound B Mode imaging combined with Doppler flow measurement is used to diagnose arterial and venous disease. This is particularly important in neurology , where ultrasound is used for assessing blood flow and stenoses in the carotid arteries Carotid Ultrasonography and intracerebral arteries Transcranial Doppler.
Intravascular ultrasound IVUS uses a specially designed catheter , with a miniaturized ultrasound probe attached to its distal end, which is then threaded inside a blood vessel. The proximal end of the catheter is attached to computerized ultrasound equipment and allows the application of ultrasound technology, such as piezoelectric transducer or CMUT , to visualize the endothelium inner wall of blood vessels in living individuals.
Main article: Echocardiography Echocardiography is an essential tool in cardiology , assisting in evaluation of heart valve function, such as stenosis or insufficiency , and strength of cardiac muscle contraction.
This includes differentiating cardiac causes of acute breathlessness from pulmonary causes, and the Focused Assessment with Sonography for Trauma FAST exam for assessing significant hemoperitoneum or pericardial tamponade after trauma. Other uses include assisting with differentiating causes of abdominal pain such as gallstones and kidney stones. Emergency Medicine Residency Programs have a substantial history of promoting the use of bedside ultrasound during physician training.
Further information: Abdominal ultrasonography and Endoanal ultrasound Abdominal and endoanal ultrasound are frequently used in gastroenterology and colorectal surgery. In abdominal sonography, the solid organs of the abdomen such as the pancreas , aorta , inferior vena cava , liver , gall bladder , bile ducts , kidneys , and spleen are imaged. However, sound waves are blocked by gas in the bowel and attenuated to differing degrees by fat, sometimes limiting diagnostic capabilities in this area.
The appendix can sometimes be seen when inflamed as in e. Endoanal ultrasound is used particularly in the investigation of anorectal symptoms such as fecal incontinence or obstructed defecation. It images the immediate perianal anatomy and is able to detect occult defects such as tearing of the anal sphincter. Ultrasonography of liver tumors allows for both detection and characterization. It commonly uses transducers designed for approaches through the lower abdominal wall, curvilinear and sector, and specialty transducers such as endovaginal.
It is currently believed that the risk of leaving these conditions undiagnosed is greater than the small risk, if any, associated with undergoing an ultrasound scan. However, even where sonography is used routinely in obstetric appointments, its use for non-medical purposes such as fetal "keepsake" videos and photos is discouraged.
Assess fetal growth for evidence of intrauterine growth restriction IUGR Check for fetal movement and heartbeat. Determine the sex of the baby According to the European Committee of Medical Ultrasound Safety ECMUS  Ultrasonic examinations should only be performed by competent personnel who are trained and updated in safety matters.
Ultrasound produces heating, pressure changes and mechanical disturbances in tissue. Biological effects of non-thermal origin have been reported in animals but, to date, no such effects have been demonstrated in humans, except when a microbubble contrast agent is present. Nonetheless, care should be taken to use low power settings and avoid pulsed wave scanning of the fetal brain unless specifically indicated in high risk pregnancies.
Ultrasound scanners have different Doppler -techniques to visualize arteries and veins. The most common is colour doppler or power doppler, but also other techniques like b-flow are used to show bloodflow in an organ. By using pulsed wave doppler or continuous wave doppler bloodflow velocities can be calculated. Hemodynamics blood circulation [ edit ] Blood velocity can be measured in various blood vessels, such as middle cerebral artery or descending aorta , by relatively inexpensive and low risk ultrasound Doppler probes attached to portable monitors .
These provides non-invasive or transcutaneous non-piecing minimal invasive blood flow assessment. Otolaryngology head and neck [ edit ] Neck ultrasound. Most structures of the neck, including the thyroid and parathryoid glands , lymph nodes , and salivary glands , are well-visualized by high-frequency ultrasound with exceptional anatomic detail.
Ultrasound is the preferred imaging modality for thyroid tumors and lesions, and ultrasonography is critical in the evaluation, preoperative planning, and postoperative surveillance of patients with thyroid cancer.
Many other benign and malignant conditions in the head and neck can be evaluated and managed with the help of diagnostic ultrasound and ultrasound-guided procedures.
Neonatology[ edit ] In neonatology , transcranial Doppler can be used for basic assessment of intracerebral structural abnormalities, bleeds, ventriculomegaly or hydrocephalus and anoxic insults Periventricular leukomalacia.
The ultrasound can be performed through the soft spots in the skull of a newborn infant Fontanelle until these completely close at about 1 year of age and form a virtually impenetrable acoustic barrier for the ultrasound. The most common site for cranial ultrasound is the anterior fontanelle.
The smaller the fontanelle, the poorer the quality of the picture. Ophthalmology eyes [ edit ] In ophthalmology and optometry , there are two major forms of eye exam using ultrasound: A-scan ultrasound biometry , commonly referred to as an A-scan short for Amplitude scan. It is an A-mode that provides data on the length of the eye , which is a major determinant in common sight disorders, especially for determining the power of an intraocular lens after cataract extraction.
B-scan ultrasonography, or B-scan, which is a B-mode scan that produces a cross-sectional view of the eye and the orbit. It is commonly used to see inside the eye when media is hazy due to cataract or any corneal opacity. Pulmonology lungs [ edit ] In pulmonology , endobronchial Ultrasound EBUS probes are applied to standard flexible endoscopic probes and used by pulmonologists to allow for direct visualization of endobronchial lesions and lymph nodes prior to transbronchial needle aspiration. Among its many uses, EBUS aids in lung cancer staging by allowing for lymph node sampling without the need for major surgery.
In a pelvic sonogram, organs of the pelvic region are imaged. This includes the uterus and ovaries or urinary bladder. Males are sometimes given a pelvic sonogram to check on the health of their bladder, the prostate , or their testicles for example to distinguish epididymitis from testicular torsion. In young males, it is used to distinguish more benign testicular masses varicocele or hydrocele from testicular cancer , which is highly curable but which must be treated to preserve health and fertility.
There are two methods of performing a pelvic sonography — externally or internally. The internal pelvic sonogram is performed either trans vaginally in a woman or transrectally in a man. Deep Venous Thrombosis [iBook]. Expand your ultrasound skills and learn to evaluate patients for DVT using ultrasound at the point-of-care.
The first of the Practical Ultrasound Series, Focused Ultrasound for Deep Venous Thrombosis DVT introduces providers to the key concepts, technical considerations, and image acquisition and interpretation skills required to evaluate patients for DVT using ultrasound at the point-of-care. A combination of text, image galleries, narrated video clips and interactive media is used to provide an immersive educational experience for the emergency physician interested in developing or expanding their ultrasound skills.
The ultrasound "virtual issue" is a collection of key articles from Academic Emergency Medicine on the use of ultrasound in emergency medicine. Ultrasound can be used by the emergency physician to help diagnose a range of conditions, often at the bedside, and perform a variety of procedures.
This collection of papers focuses on the situations and conditions that the emergency physician may need to employ ultrasound in, as well as covering education and training. This virtual issue will be updated on an ongoing basis as new articles are published. Ultrasound-Guided Regional Anesthesia: Interactive Guide 4 Beginners [iBook].

It is a practical and visually engaging introductory book that helps maximize learning through interaction with rich media. Embedded throughout the book are visual aids that include enhanced videos, interactive galleries, detailed review of sonoanatomy, as well as self-assessment quizzes that provide immediate feedback. Manual of Regional Anesthesia [mulit-part pdf]. Regional anesthesia refers to a group of techniques performed either at the neuraxial or peripheral nerve levels that render part of the body insensate to pain.
In this manual I discuss regional anesthesia related issues as well as nerve block techniques commonly used in the United States with special emphasis on the techniques we perform at Cook County Hospital in Chicago.
Cardiac and Critical Care Ultrasonography [iBook]. The purpose of this book is to introduce medical trainees and practitioners to the perioperative use of ultrasound, specifically covering transesophageal echocardiography and transthoracic echocardiography in detail, as well as introducing elements of critical care ultrasonography including thoracic, abdominal, deep venous, and cerebral ultrasound.
Included in the text are over references to previously published works primarily peer-reviewed literature and more than images and embedded videos. This text is meant to be overview of the examination of the shoulder with ultrasound assistance.
The objectives that will be addressed are as follows: All chapters are accompanied by interactive video, to enhance the learning experience.
It provides students with an interactive entry-level text on the subjects of Cardiac, Lung and Upper Abdominal ultrasonography and also offers medical educators a simple and lightweight modular framework to overlay on top of their busy curricula.
An essential resource for the initial evaluation of the acutely ill or injured obstetrical patient. Written by experts in both emergency medicine and obstetrics, whether the patient is in the first, second, or third trimester, this ACEP book covers the critical obstetrical conditions you need to be able to diagnose with point-of-care ultrasound. Each chapter contains referenced text, key points, pearls, and numerous videos and image banks. Radiology Basics: Cross-sectional Imaging [iBook].
Sachita Shah, is a concise review of bedside, clinician-performed ultrasound, with focus on specific diagnostic questions and disease processes common in the developing world. Does my patient with shortness of breath have heart failure or fluid around the heart?
Is this trauma patient bleeding internally? As clinicians working in resource poor settings know, the right answers to these questions can save a patient's life, and ultrasound, in trained hands, is an invaluable tool for speedy and accurate diagnosis of life-threatening conditions.
The Practical Guide to Critical Ultrasound iBook in 2 volumes is a free resource for point-of-care users caring for patients in emergency and critical care environments. We designed this interactive image and narrated video focused book to be a quick reference and a just-in-time learning tool. This iBook has three unique aspects. The two chapters at the end of volume 2 collate landmark publications for the field.
The critical care ultrasound protocol chapter provides a nearly complete set of reference information as providers consider an organized approach to the emergency and critical patient. The final society protocol chapter assists the reader with the most up-to-date specialty endorsed standards and guidelines.
Most chapters fall under one of two categories: We are very proud of the extensive number of contributors nationally and internationally. We acknowledge and welcome that not all chapters are the same. The tone and the approach differ in small ways.
