BACKGROUND Round ligament varices (RLV) are rare and are almost exclusively seen in pregnant women. RLV may clinically resemble an inguinal hernia, inguinal mass, or other pathology involving the inguinal canal and round ligament. Ultrasound imaging is important to make the diagnosis of RLV. CASE REPORT A 34-year-old Hispanic woman, gravida 1 para 0, at 34 weeks gestation, presented to our outpatient department with a complaint of a small, painless, reducible right inguinal mass. Gray-scale sonography showed an asymmetric right inguinal anechoic mass composed of multiple serpentine tubular channels, which became more prominent when the patient performed a Valsalva maneuver...

The zygomatico-orbital artery is the largest artery in the temporal area. With the increasing number of reconstructive and aesthetic surgeries in the area, in-depth understanding of this artery is needed. Thus, the aim of this anatomical study was to determine more information on the zygomatico-orbital artery using contrast-enhanced three-dimensional computer tomography (CT) and color-flow Doppler sonography. On the basis of CT images taken between October 2015 and October 2016 for diagnosing and treating maxillofacial conditions, 50 patients were selected...

OBJECTIVES: Cochlear implantation (CI) has been the most successful procedure for restoring hearing in a patient with severe and profound hearing loss. However, possibly owing to the variable brain functions of each patient, its performance and the associated patient satisfaction are widely variable. The authors hypothesize that peripheral and cerebral circulation can be assessed by noninvasive and globally available methods, yielding superior presurgical predictive factors of the performance of CI in adult patients with postlingual hearing loss who are scheduled to undergo CI...

Ultrasound imaging may have an impact in management patients with rheumatoid arthritis. Through technological improvements, ultrasonography, has become an established imaging technique for the diagnosis and the follow up of this inflammatory chronic disease. In fact, ultrasounds, allow follow up during treatment by evaluating synovitis count and assessment of synovial vascularization by Power Doppler. Besides, erosions are found sooner and more frequently by ultrasonography than with conventional radiography...

PURPOSE AND HYPOTHESIS: Mid-portion Achilles tendinopathy is characterized by a proliferation of small vessels, called neovascularization, which can be demonstrated by power Doppler sonography (PD). Neovascularization can be correlated with diagnosis and consequent therapies focused on vascular supply. Published data regarding the relationship between neovascularisation and symptoms, such as pain and disability, are contradictory. The hypothesis that contrast-enhanced ultrasound (CEUS) could detect with more sensibility than PD the new vessel ingrowth in human degenerated Achilles tendons and therefore the correlation of neovascularization with pain and disability, was evaluated...

Chest wall ultrasound has been awarded little interest in the literature, with chest wall anatomy described only in limited extent. The objective of this study has been to discuss the methodology of chest wall ultrasound and the sonographic anatomy of the region to facilitate professional evaluation of this complex structure. The primarily used transducer is a 7-12 MHz linear one. A 3-5 MHz convex (curvilinear) transducer may also be helpful, especially in obese and very muscular patients. Doppler and panoramic imaging options are essential...

REVIEW
Vincent Issac Lau, Robert Thomas Arntfield
In the unconscious patient, there is a diagnostic void between the neurologic physical exam, and more invasive, costly and potentially harmful investigations. Transcranial color-coded sonography and two-dimensional transcranial Doppler imaging of the brain have the potential to be a middle ground to bridge this gap for certain diagnoses. With the increasing availability of point-of-care ultrasound devices, coupled with the need for rapid diagnosis of deteriorating neurologic patients, intensivists may be trained to perform point-of-care transcranial Doppler at the bedside...

OBJECTIVES: Diagnosing fetal heart failure remains challenging because it is difficult to know how well the fetal myocardium will perform as loading conditions change. In adult cardiology, natriuretic peptides (NPs) are established marker of heart failure. However, the number of studies investigating NP levels in fetuses is quite limited. The aim of this study was to evaluate the significance of plasma NP levels in the assessment of heart failure in fetuses with congenital heart defect (CHD) and arrhythmia...

BACKGROUND AND AIM: It has been speculated that impaired salivary flow contributes to abnormal acid clearance in patients with erosive esophagitis (EE). For easy and objective assessment of salivary function, we developed a salivary gland blood flow measurement technique using continuous-wave Doppler sonography. In the present study, we evaluated the salivary secretory function in patients with EE and those with nonerosive reflux disease (NERD) using this method. METHODS: Doppler waveform analysis was performed on the facial artery to assess blood inflow to the submandibular gland of 30 healthy subjects (HS)...
