INTRODUCTION: Ultrasound of the inferior vena cava (IVC-US) has been used to estimate intravascular volume status and fluid removal during a hemodialysis session. Usually, renal nurses rely on other, imprecise methods to determine ultrafiltration. To date, no study has examined whether renal nurses can reliably perform ultrasound for volume assessment and for potential prevention of intradialytic hypotension. This pilot study aimed to determine if a renal nurse could master the skill of performing and correctly interpreting Point of Care Ultrasound on patients receiving hemodialysis...

OBJECTIVES: To assess whether level of agreement among experts in distinguishing between septate and normal/arcuate uterus using subjective judgments from review of coronal view from three-dimensional ultrasound. We also aim to determine the inter-observer reliability and diagnostic test accuracy of three measurements suggested by recent guidelines, using the most voted option by experts (CUME - Congenital Uterine Malformation by Experts) as a reference standard. METHODS: Images of the coronal plane of the uterus from 100 women with suspected fundal internal indentation were anonymized and submitted to 15 experts (5 clinicians, 5 surgeons and 5 sonologists)...

During routine ultrasound assessment of the fetal brain for biometry estimation and detection of fetal abnormalities, accurate imaging planes must be found by sonologists following a well-defined imaging protocol or clinical standard, which can be difficult for non-experts to do well. This assessment helps provide accurate biometry estimation and the detection of possible brain abnormalities. We describe a machine-learning method to assess automatically that transventricular ultrasound images of the fetal brain have been correctly acquired and meet the required clinical standard...

BACKGROUND: An impaired cerebrospinal venous drainage was postulated to be a cofactor in the multifactorial pathogenesis of multiple sclerosis (MS). Chronic cerebrospinal venous insufficiency (CCSVI) is characterized by abnormalities of the main extracranial cerebrospinal venous outflow routes, which can be detected by color Doppler Ultrasound (CDUS) using 5 venous hemodynamic (VH) criteria. Discrepant results between different investigators were reported in the past, therefore the usefulness and applicability of the CCSVI CDUS-based diagnosis in clinical research and practice has been questioned...

We present a retrospective review of 8 patients (6 women and 2 men, with an age range of 46-80 years; mean age, 60.2 years) in whom sonography was used to diagnose a calcaneal stress fracture. Sonography was performed because of a clinical suspicion of soft tissue injuries. Two patients were first assessed by standard radiography; for the remaining patients, sonography was the first imaging technique used. Patients were subsequently examined by magnetic resonance imaging, except for 1 patient in whom the diagnosis was made only on a clinical-sonographic correlation...

Transcranial sonography (TCS) shows an increased echogenic area of the substantia nigra (SN) in patients with Parkinson disease (PD). It has been increasingly used in the diagnosis of PD and its differentiation from atypical parkinsonian syndromes. Here, we studied the diagnostic accuracy of SN TCS in Italian patients. In this blinded cross-sectional study (NOBIS study), two expert neuro-sonologists performed TCS in 25 PD patients and 29 age- and sex-matched controls. The study participants were completely hidden to the TCS investigators using large drapery...

REVIEW
Jenna M Turocy, Beryl R Benacerraf
This review summarizes the current evidence regarding the diagnostic accuracy of sonography (US) in women with deep infiltrating endometriosis (DIE). It is well known that transvaginal ultrasound (TVUS) can detect ovarian endometriomas with a high degree of sensitivity. In recent years, US has also been used to detect DIE. In the hands of an experienced sonologist, the sensitivity and specificity of TVUS in the detection of DIE is comparable to those of MRI. TVUS can eliminate the need for an MRI in the majority of patients and reduce the need for diagnostic laparoscopy, proving to be an important tool in preoperative planning...

Our unit has been providing antenatal consultations for 30 years following the discovery of limb malformation with the fetus. Each of these consultations is specific and carried out by a multi-professional team. It requires a physical and rehabilitation doctor, an orthopedic surgeon, an occupational therapist for upper limb malformation, a physiotherapist for lower malformation and a psychologist. This multidisciplinary consultation is unique because of each pregnancy story, because of each patient life story but also because of the words used by the sonologist when announcing the diagnosis...

Various approaches to 2-dimensional speckle tracking have been used to evaluate left ventricular function and deformation in the fetus, child, and adult. In 2015, because of differences in imaging devices and analytical programs, the cardiology community published a consensus document proposing standards for pediatric/adult deformation imaging using 2-dimensional speckle tracking. The understanding and application of deformation imaging in the fetus have been limited by a lack of uniform software, terminology, techniques, and display...

BACKGROUND: Point-of-care ultrasound guidance using a linear probe is well established as a tool to increase safety when performing a supradiaphragmatic cannulation of the internal jugular central vein. However, little data exist on which probe is best for performing a supradiaphragmatic cannulation of the subclavian vein. METHODS: This was a prospective, observational study at a single-site emergency department, where 5 different physician sonologists evaluate individual practice preference for visualization of the subclavian vein using a supraclavicular approach with 2 different linear probes and 1 endocavitary probe...
