OBJECTIVES: To assess adoption of pre-biopsy prostate MRI in the United States and evaluate factors associated with MRI-Bx use. Prior reports have shown improved cancer detection with magnetic resonance image-guided prostate biopsies (MRI-Bx) vs. transrectal ultrasound-guided methods (TRUS-Bx). Population-based trends of their use and outcomes have not been previously characterized. METHODS: Using private insurance claims (2009-2015), we identified men who underwent prostate biopsy...

The use of transthoracic ultrasound has acquired a wide consensus among respiratory physicians during the last few years. The developing of portable and easily available devices favorites patient's bedside evaluation. Transthoracic ultrasound provides rapid, real-time and low-cost diagnostic information, allowing image-guided chest interventions and reducing procedural risks. The different acoustic impedance between aerated and not aerated organs produces artifacts known as A lines, B lines, sliding sign, lung point, etc...

There has been great effort to improve clinical outcome in percutaneous treatment for coronary artery disease. Complementary to coronary angiography, intravascular ultrasound (IVUS) provides in vivo tomographic anatomic information, enabling to evaluate from the lumen to the vessel wall. As a result, IVUS has had a pivotal role to understand pathophysiology of coronary artery disease and improve clinical outcome. It provides preprocedural information to evaluate stenosis severity and plaque characteristics and helps with optimal stent deployment, minimizing underexpansion and geographic miss that are the major mechanisms of stent failure...

OBJECTIVE: This study investigates the impact of introducing a post-general anesthesia ultrasound mapping (PAUS) on the type of vascular access chosen for hemodialysis in patients without previous accesses. METHODS: 203 of 297 consecutive patients met inclusion criteria and were reviewed. Within-subjects analysis was performed on patients with both an outpatient ultrasound-guided vein mapping and a PAUS using sign tests and Wilcoxon signed ranked tests. Further, a between-subjects analysis added patients with only the outpatient vein mapping; demographic and comorbidity data were analyzed using t-tests and chi-squared tests...

BACKGROUND: Salivary gland hypofunction and xerostomia are major complications to head and neck radiotherapy. This trial assessed the safety and efficacy of adipose tissue-derived mesenchymal stem cell (ASC) therapy for radiation-induced xerostomia. PATIENT AND METHODS: This randomized, placebo-controlled phase 1/2 trial included 30 patients, randomized in a 1:1 ratio to receive ultrasound-guided transplantation of ASCs or placebo to the submandibular glands. Patients had previously received radiotherapy for a T1-2, N0-2A, human papillomavirus-positive, oropharyngeal squamous cell carcinoma...

BACKGROUND AND OBJECTIVES: This study aimed to describe and assess the accuracy and feasibility of a novel technique for ultrasound-guided maxillary nerve block using the lateral pterygoid plate (LPP) approach via the pterygopalatine fossa (PPF) in a soft cadaveric model. METHODS: Ten soft cadavers were studied. The curved array ultrasound transducer probe was applied over 1 side of the face of the cadavers in the open-mouth posture. It was placed transversely below the zygomatic arch for identifying the border of the maxillary tuberosity and the LPP...

Recent literature shows that perioperative ultrasound guidance of surgery for palpable and nonpalpable breast carcinoma results in improved surgical effectiveness. Ultrasound-guided surgery can easily lead to significant improvement of the number of radical resections and can decrease the need for additional surgery or extra radiotherapy. Ultrasound-guided surgery also contributes to a reduction in the amount of excessive breast tissue removal, which means the final cosmetic result is better. Ultrasound-guided surgery is cost-effective and easy to learn...

BACKGROUND: Locoregional anaesthetic techniques can facilitate certain surgeries being performed under standing procedural sedation. The second and third spinal cervical nerves (C2, C3) are part of the cervical plexus and provide sensory innervation to the peri-laryngeal structures in people; block of these nerves might permit laryngeal lateralisation surgery in horses. OBJECTIVES: To describe the anatomical basis for an ultrasound-guided cervical plexus block in horses...

BACKGROUND: The use of intraoperative ultrasound (iUS) has increased in the last 15 years becoming a standard tool in many neurosurgical centers. Our aim was to assess the utility of routine use of iUS during various types of intracranial surgery. We reviewed our series to assess ultrasound visibility of different pathologies and iUS applications during the course of surgery. MATERIALS AND METHODS: This is a retrospective review of 162 patients who underwent intracranial surgery with assistance of the iUS guidance system (SonoWand)...

We developed a linear ultrasound array-based real-time photoacoustic imaging system with a compact coaxial excitation handheld photoacoustic imaging probe for guiding sentinel lymph node (SLN) needle biopsy. Compared with previous studies, our system and probe have the following advantages: (1) the imaging probe is quite compact and user-friendly; (2) laser illumination and ultrasonic detection are achieved coaxially, enabling high signal-to-noise ratio; and (3) GPU-based image reconstruction enables real-time imaging and displaying at a frame rate of 20 Hz...

Despite recent advances in screening methods, lung cancer remains the leading cause of cancer-related deaths worldwide. By the time lung cancer becomes symptomatic and patients seek treatment, it is often too advanced for curative measures. Low-dose computed tomography (CT) screening has been shown to reduce mortality in patients at high risk of lung cancer. We present a 66-year-old man with a 50-pack-year smoking history who had a right upper lobe (RUL) pulmonary nodule and left lower lobe (LLL) consolidation on a screening CT...

AIMS: The aim of the study was to evaluate the clinical utility and safety of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with mediastinal and hilar lymphadenopathy and to explicitly describe the utility of this procedure in patient's outcome. METHODS: A retrospective review and analysis was conducted on 52 patients with mediastinal or hilar lymphadenopathy who underwent EBUS-TBNA from June 2012 to June 2016. All the patients were evaluated by computed tomography (CT) chest with contrast before EBUS examination...

The precise sizing of the stent graft in thoracic endovascular aortic repair (TEVAR) affects aortic remodeling and hence, further outcome. Covering the proximal entry tear is essential for successful treatment of Type B aortic dissection. Intravascular ultrasound (IVUS) enables real-time aortic diameter assessment, and is especially useful when computed tomography (CT) image quality is poor. IVUS, however, is not routinely utilized due to cost inefficiency. We investigated the impact of IVUS-assisted stent graft sizing on aortic remodeling in TEVAR...

BACKGROUND AND OBJECTIVES: General anesthesia for breast surgery may be supplemented by using a regional anesthetic technique. We evaluated the efficacy of the first pectoral nerve block (Pecs I) in treating postoperative pain after breast cancer surgery. METHODS: A randomized, double-blind, dual-centered, placebo-controlled trial was performed. One hundred twenty-eight patients scheduled for unilateral breast cancer surgery were recruited. A multimodal analgesic regimen and surgeon-administered local anesthetic infiltration were used for all patients...

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) has been the cornerstone in the management of malignant jaundice to provide symptomatic relief and/or to allow chemotherapy. Difficult biliary cannulation or the presence of concomitant duodenal obstruction may lead to its failure.

PURPOSE: Facet joint insertion is a common treatment of chronic pain in the back and spine. This procedure is often performed under fluoroscopic guidance, where the staff's repetitive radiation exposure remains an unsolved problem. Robotic ultrasound (rUS) has the potential to reduce or even eliminate the use of radiation by using ultrasound with a robotic-guided needle insertion. This work presents first clinical data of rUS-based needle insertions extending previous work of our group...
