The optimum technique for histological confirmation of the nature of a parotid mass remains controversial. Fine needle aspiration cytology (FNAC), which has traditionally been used, is associated with high non-diagnostic and false negative rates, and ultrasound (US)-guided core biopsy and frozen section have been explored as alternatives. US-guided core biopsy is more invasive than FNAC, but is...

Abstract Ultrasonography use in the emergency department (ED) has been well established. The use of ultrasonography that falls into the traditional practice of the emergency nurse is peripheral intravenous (IV) access. Benefits of using ultrasonography for peripheral IV access include decreasing patient throughput, cost reduction, decreasing complications, increased patient and emergency medici...

Surgical procedures guided by non-optical imaging represent a growing proportion of medical interventions. The goal of this type of approach is to reduce the invasiveness of current procedures or to treat disease using new procedures which would not possible without the assistance of medical imaging. The field of cardiac surgery represents a medical subspecialty where image-guided interventions...

Background Musculoskeletal ultrasound (US) is a rapidly evolving and powerful diagnostic modality, which is gaining popularity for the evaluation and management of joint damage and soft tissue diseases in children with JIA. Several studies have shown that clinical examination underestimates the presence of intra-articular fluid when compared to US. US guided aspiration allows direct observation...

We evaluated ultrasonography (US) findings between benign and malignant phyllodes tumors and analyzed diagnostic performance of US-guided core needle biopsy (CNB) for phyllodes tumors. Surgically removed phyllodes tumors of 168 women were divided into two groups according to the benign and malignant (including borderline tumor) groups and 116 were benign and 52 were malignant. On US, the comple...

BACKGROUND Preoperative evaluation of the axilla, an important prognostic determinant for patients with invasive breast cancer, is achieved by non- or minimally invasive methods to avoid the potential hazards of operative intervention. The aim of this study was to determine statistical power of axillary ultrasound (US) and US-guided fine needle aspiration cytology (FNAC) for evaluating axillary...
