When the human body is anesthetized, the human nerve tissue will be greatly affected, which also affects the breathing of the human body. The respiration during anesthesia is a lack of initiative, and the energy efficiency of the diaphragm in the lungs is very important to the safety of anesthesia. In this paper, the application of the ultrasound evaluation of the diaphragm in clinical anesthesia was studied. In this paper, 24 patients who underwent lung examination under medical anesthesia at our hospital were evaluated by the ultrasound vertical mixed echo method. Through patient voluntary s

Lung ultrasound has become a part of the daily examination of physicians working in intensive, sub-intensive, and general medical wards. The easy access to hand-held ultrasound machines in wards where they were not available in the past facilitated the widespread use of ultrasound, both for clinical examination and as a guide to procedures; among point-of-care ultrasound techniques, the lung ultrasound saw the greatest spread in the last decade. The COVID-19 pandemic has given a boost to the use of ultrasound since it allows to obtain a wide range of clinical information with a bedside, not ha

Ultrasound assessments of children with possible acute appendicitis (AA) are often nondiagnostic. We aimed to identify the predictors of nondiagnostic ultrasound and to investigate the outcomes. A retrospective review was conducted on children aged 4 to 17 years evaluated in 2013 for AAwith ultrasound at a tertiary hospital pediatric emergency department. Demographics, clinical data, and outcomes were analyzed. Of 528 children, 194 (36.7%) had diagnostic ultrasounds and 334 (63.3%) had nondiagnostic ultrasounds.

In this article, the authors review the role of ultrasound guidance in MSK mini-invasive surgery. Ultrasound imaging has become an important tool in the field of musculoskeletal examination and has advantages over the X-ray guidance traditionally used by orthopaedic surgeons. Ultrasound provides the 3D localization of the area where the instruments are being used, does not require X-ray’s certified personnel, and poses less of a health risk to the patient and the medical staff.

Introduction: Formal ultrasound imaging, with use of ultrasound technicians and radiologists, provides a valuable diagnostic component to patient care in the Emergency Department (ED). Outside of regular weekday hours, ordering formal ultrasounds can produce logistical difficulties. EDs have developed protocols for next-day ultrasounds, where the patient returns the following day for imaging and reassessment by an ED physician. This creates additional stress on ED resources – personnel, bed space, finances – that are already strained. There is a dearth of literature regarding the use of next-d

The incidence of DDH in most developed countries is reported to be 1.5 to 20 cases per 1000 births. The Canadian Task Force on Preventive Health Care reports fair evidence to include a serial clinical examination of the hips by a trained clinician in the periodic health examination of all infants until they are walking independently.

Feminist anthropologists have mostly criticized ultrasound technology for invading the intimate experience of pregnancy and making women “invisible.” This article focuses on socalled “entertainment” ultrasounds to explore

The waves have a very high frequency, equal to approximately 20 kHz, divided into two categories (i.e., low-intensity and high-intensity waves) and cannot be perceived by the human ear. Ultrasound waves are emitted from an ultrasound transducer. The choice of frequency of the transducer is important as higher frequencies give increased spatial resolution.

A pre-procedural ultrasound of the lumbar spine is frequently used to facilitate neuraxial procedures. The aim of this review is to examine the evidence sustaining the utilization of pre-procedural neuraxial ultrasound compared to conventional methods. We perform a systematic review of randomized controlled trials with meta-analyses. We search the electronic databases Medline, Cochrane Central, Science Direct and Scopus up to 1 June 2019. We include trials comparing a pre-procedural lumbar spine ultrasound to a non-ultrasound-assisted method. The primary endpoints are technical failure rate, f

Introduction Although guidelines recommend repeat ultrasound in the setting of an incomplete fetal anatomic survey, the clinical utility of this practice has not been established. As such, we aimed to assess the yield of repeat ultrasound for anomaly detection following an incomplete survey. Materials and Methods This is a retrospective cohort study of all singletons who underwent a midtrimester anatomic ultrasound at University of Alabama at Birmingham (UAB) from 2006 to 2014. Patients with an incomplete ultrasound underwent repeat examinations until completion. The population was divided int

In a study of 80 patients suspected of ovarian torsion and necrosis admitted to our hospital between January and December 2023, we analyzed the results of abdominal and vaginal ultrasounds with surgical diagnoses as the reference. Of the 80 cases, 74 were confirmed as ovarian torsion, accounting for 92.50%, while the remaining diagnoses included ruptured corpus luteum cysts, periapendiceal abscesses, and ruptured ectopic pregnancies, each with 2 cases. Abdominal ultrasound identified 63 cases of ovarian torsion and 17 cases of non-ovarian torsion, whereas vaginal ultrasound identified 73 cases

ABSTRACT New technology in ultrasound imaging is allowing women to view more visually precise images of their fetuses than ever before. Maternal-fetal bonding describes the attachment interaction that forms between a mother and her unborn child. Ultrasound diagnosis modalities including two-dimensional (2D), three-dimensional (3D) and four-dimensional (4D) may create differences in the amount of maternal-fetal bonding, depending on the modality used. When relevant literature was reviewed on this topic, no significant difference between maternal-fetal bonding was found when comparing 2D vs 3D v

A freehand three-dimensional (3D) ultrasound system is a method of acquiring images using a 3D ultrasound probe or conventional two-dimensional (2D) ultrasound probe to give a 3D visualization of an object inside the body. Ultrasounds are used extensively in clinical applications since they are advantageous in that they do not bring dangerous radiation effects and have a low cost. However, a probe calibration method is needed to transform the coordinate position into a 3D visualization display, especially for image-guided intervention. The current ultrasound probe calibration system usually us

Carotid duplex ultrasound is commonly used to diagnose various carotid artery diseases due to it being noninvasive and easy to perform. Carotid atherosclerosis is a major indicator for the need to perform carotid duplex ultrasound, which can determine the degree of stenosis, plaque characteristics, and intima-media thickness. It can also be used to screen and follow-up after carotid revascularization. Here we discuss the standard techniques, interpretations, and clinical indicators for carotid duplex ultrasounds.

The application of thoracic ultrasound examination has not long been developed because ultrasound’s interaction with the lung does not generate an anatomical image but an artifactual one. Subsequently, the evaluation of pulmonary artifacts and their correlation to specific diseases allowed the development of ultrasound semantics. Currently, pneumonia still represents one of the main causes of hospitalization and mortality. Several studies in the literature have demonstrated the ultrasound features of pneumonia.

Background/Objectives: The goal of educators is to leave no learner behind. Ultrasounds require dexterity and 3D image interpretation. They are technologically complex, and current medical residency programs lack a reliable means of assessing this ability among their trainees. This prompts consideration as to whether background characteristics or certain pre-existing skills can serve as indicators of learning aptitude for ultrasounds. The objective of this study was to determine whether these characteristics and skills are indicative of learning aptitude for ultrasounds. Methods: This prospect
