Although ultrasound (US) guidance for venous access is becoming the "standard of care" for preventing access site complications, its feasibility for arterial access has not been fully investigated, especially in the neuro-interventional population. We conducted the first prospective cohort study on US-guided femoral artery access during neuro-interventional procedure. This study included 64 con...

BACKGROUND AND OBJECTIVES To assess frequency and significance of enlarged nonpalpable supraclavicular lymph nodes with routine ultrasound (US) evaluation and US-guided fineneedle aspiration biopsy (FNAB) for the diagnosis and staging of patients with lung cancer. MATERIALS AND METHODS 106 consecutive patients with lung cancer and nonpalpable supraclavicular lymph nodes were evaluated with ce...

BACKGROUND During ultrasound (US)-guided cannulation of the subclavian vein (SCV) via an infraclavicular route, the view of the needle behind the clavicle may be obscured. This study describes the US-guided supraclavicular cannulation of the brachiocephalic vein (BCV). METHODS The 25 mm broadband linear array US probe was placed in the supraclavicular region to obtain a longitudinal view of t...

BACKGROUND Modern ultrasound (US) is an attractive alternative to anatomical landmark-, nerve stimulation-, and fluoroscopic-guided techniques for interventional procedures performed to treat chronic pain syndromes. METHODS In this review, we evaluated the effects of US guidance compared with traditional guidance techniques on performance, efficacy, and safety outcomes for interventional chro...

Ultrasound sonography (US) plays an important role in the assessment of lymph nodes in oncology. However, ultrasound findings are often equivocal in not allowing the differentiation of reactive from metastatic lymph nodes. Here, we present the successful use of contrast-enhanced US in the assessment of a metastatic lymph node, improving the performance of conventional US and optimising the US-g...

The objectives of this investigation are (a) to study the similarities between proof planning and schema-guided programming (i.e., between proof methods and programming schemas), and (b) to express the latter in terms of the former, so as to be able to use any proof planner as an existing implementation platform for developing the first schema-guided developer of (standard or constraint) logic ...

Prostate cancer is one of the most common neoplasms in men. Transrectal ultrasound (TRUS)-guided systematic biopsy has a crucial role in the diagnosis of prostate cancer. However, it shows limited value with gray-scale ultrasound alone because only a small number of malignancies are visible on TRUS. Recently, new emerging technologies in TRUS-guided prostate biopsy were introduced and showed hi...

UNLABELLED Conceição DB, Helayel PE, Oliveira Filho GR - A Comparative Study between Ultrasound- and Neurostimulation-Guided Axillary Brachial Plexus Block. BACKGROUND AND OBJECTIVES The use of ultrasound in Regional Blocks is increasingly more frequent. However, very few studies comparing ultrasound and neurostimulation have been conducted. The objective of this study was to compare neurosti...

Background This study aimed to evaluate the feasibility of contrast-enhanced ultrasound (CEUS) and CEUS-guided interventions in the diagnostics of MRI visible targeted US occult breast lesions. Patients and methods This retrospective study examined 10 females with 10 occult, MRI only detected breast lesions between July 2014 and April 2017. Targeted second look US followed by CEUS with 2.4 ml...

BACKGROUND The Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) study demonstrated significantly improved health outcomes at 1 year in patients randomized to multivessel percutaneous coronary intervention guided by fractional flow reserve (FFR) compared with percutaneous coronary intervention guided by angiography alone. The economic impact of routine measurement of ...
