Automated ultrasound edge-tracking software comparable to established semi-automated reference software for carotid intima-media thickness analysis.

Many commercial ultrasound systems are now including automated analysis packages for the determination of carotid intima-media thickness (cIMT); however, details regarding their algorithms and methodology are not published. Few studies have compared their accuracy and reliability with previously established automated software, and those that have were in asymptomatic adults. Therefore, this study ...

Association of lipoprotein(a) with long-term mortality following coronary angiography or percutaneous coronary intervention.

There is no consistent evidence to suggest the association of plasma lipoprotein(a) (Lp[a]) with long-term mortality in patients undergoing coronary angiography (CAG) or percutaneous coronary intervention (PCI).

Ionic-liquid-based ultrasound-assisted extraction of isoflavones from Belamcanda chinensis and subsequent screening and isolation of potential α-glucosidase inhibitors by ultrafiltration and semi-preparative high-performance liquid chromatography.

The separation of a compound of interest from its structurally similar homologues to produce high-purity natural products is a challenging problem. This work proposes a novel method for the separation of iristectorigenin A from its structurally similar homologues by ionic liquid-based ultrasound-assisted extraction and the subsequent screening and isolation of potential α-glucosidase inhibitors v...

Endoscopic Ultrasound-Guided Direct Portal Pressure Measurement Using a Digital Pressure Wire with Real-Time Remote Display: A Survival Study.

Endobronchial ultrasound elastography for the differentiation of benign and malignant lymph nodes.

Consensus statement for use and technical requirements of thyroid ultrasound in endocrinology units.

Thyroid nodule detection has increased with widespread use of ultrasound, which is currently the main tool for detection, monitoring, diagnosis and, in some instances, treatment of thyroid nodules. Knowledge of ultrasound and adequate instruction on its use require a position statement by the scientific societies concerned. The working groups on thyroid cancer and ultrasound techniques of the Span...

When a cesarean section scar is more than an innocent bystander in a subsequent pregnancy: Ultrasound to the rescue.

Over the years, cesarean section has played a pivotal role in reducing maternal and perinatal morbidity and mortality. With the rising trend of this surgery, a substantial number of pregnant women have a cesarean section scar. The scar can serve as the abode of grave conditions in subsequent pregnancies, namely cesarean scar pregnancy, morbidly adherent placenta, and scar dehiscence. Sonography ha...

The anterior complex: A visual mnemonic to aid in identification of normal structures.

The anterior complex of the fetal brain is a group of structures that are important to evaluate during the routine anatomic survey to exclude several serious brain malformations. These structures include the cavum septum pellucidum, anterior horns, interhemispheric fissure, callosal sulcus, and corpus callosum. The relationship between these structures is easily remembered with the presented visua...

Sonographic detection of a lingual node metastasis from early squamous cell cancer of the tongue.

Lingual node metastasis from early-stage squamous cell carcinoma of the tongue is uncommon and difficult to detect. We present a case of a lingual lymph node metastasis from an early tongue cancer. Sonography demonstrated a small nonpalpable lingual node on the floor of the mouth. The patient underwent complete surgical resection and had no evidence of recurrence 5 years later. © 2017 Wiley Perio...

A large intrauterine vascular lesion developing after the successful treatment of a cesarean scar pregnancy with methotrexate injection.

A cesarean scar pregnancy is a rare type of ectopic pregnancy. Induced abortion by local methotrexate (MTX) injection is an effective management approach. We describe a case in which a large intrauterine vascular lesion appeared after the sonographic-guided local injection of MTX, which successfully induced the abortion of the cesarean scar pregnancy. Although a cesarean scar pregnancy may be safe...

Massive pleural effusion on the contralateral side of a venous peripherally inserted central catheter.

A preterm newborn infant, delivered at 30 weeks of gestation and 965 g birth weight, developed respiratory distress with resistant hypoxia after a central catheter line was inserted via the right venae brachialis on postnatal day 21. Left-sided massive pleural effusion, collapsed left lung with air bronchograms, and bidirectional shunting through reopened ductus arteriosus were detected by targete...

Sonographic findings in two cases of lymphangioma of the mesocolon in adults.

Lymphangioma of the mesocolon is very rare. We report two cases of surgically resected and histologically proven mesocolic lymphangioma in adults. In both cases, ultrasound revealed a large cystic mass with multiple thin septa in the lower abdomen. A peculiar finding was the large craniocaudal sliding movement of the mass synchronized with the patient's respiration, which was a clue to the diagnos...

Transesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-B-FNA)-Pushing the boundaries in the diagnosis.

Isolated mediastinal adenopathy is a diagnostic challenge in the paediatric population, often requiring invasive surgical procedures for diagnosis. We describe a novel minimally invasive modality in a 20 month toddler-transesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-B-FNA). This is the youngest reported use of this modality, highlighting feasibility, technical issues, sa...

Anterior Segment Optical Coherence Tomography Angiography for Identification of Iris Vasculature and Staging of Iris Neovascularization: A Pilot Study.
