Abstract:
Purpose: To evaluate the capability of color Doppler ultrasonography to differentiate between benign and malignant soft-tissue tumors. Material and Methods: We reviewed the ultrasonographic (US) and color Doppler (CD) findings in 46 consecutive patients with a palpable periskeletal mass. The presence of 3 or more vascular hila and of tortuous and irregular internal vessels within the lesions was considered an indication of malignancy. The CD diagnosis was compared with that obtained at US alone. Results: The sensitivity and specificity of CD were respectively 85% and 92%; these values were hig

Abstract:
Medical microrobots (MRs) hold the potential to radically transform several interventional procedures. However, to guarantee therapy success when operating in hard-to-reach body districts, a precise and robust imaging strategy is required for monitoring and controlling MRs in real-time. Ultrasound (US) may represent a powerful technology, but MRs' visibility with US needs to be improved, especially when targeting echogenic tissues. In this context, motions of MRs have been exploited to enhance their contrast, e.g., by Doppler imaging. To exploit a more selective contrast-enhancement mechanism,

Abstract:
Introduction: In recent years, ultrasonography has been used in an increasing number of fields, such as dermatology, aesthetic medicine and cosmetology. For skin imaging, research has shown the usefulness of both classic scanners equipped with linear transducers, and high-frequency scanners with mechanical transducers. An increasing number of reports indicating high usefulness of Doppler sonography have been published recently. The aim of this study was to assess the usefulness of high-frequency Doppler imaging in the diagnosis of vascular complications after aesthetic procedures using tissue

Abstract:
Background In cardiac patients, pulmonary capillary wedge pressure (PCWP) is estimated using color M-mode Doppler study of left ventricular filling and Doppler tissue imaging. The goal of this study was to assess whether echocardiography accurately estimates PCWP in critically ill patients. Methods Sixty ventilated patients admitted for septic shock and acute lung injury were prospectively studied using simultaneously transesophageal echocardiography and pulmonary artery catheterization. Initial PCWP values and their changes measured invasively were compared to initial values and corresponding

Abstract:
Pulmonary sequestrations are congenital masses of aberrant, nonfunctioning pulmonary tissue that usually do not connect with the bronchial tree and derive their arterial blood supply from systemic vessels, most often the distal thoracic or upper abdominal aorta. The majority of sequestrations are intralobar and contained within the visceral pleura of the normal lung; these usually have their venous drainage to the pulmonary venous system. Extralobar sequestrations have a separate pleural covering and usually drain to systemic veins or the portal venous system.1-3 Patients most often come to cl

Abstract:
Abstract Objective The aim of this study was to assess ovarian blood flow characteristics by applying transabdominal color Doppler ultrasonography during the course of the estrous cycle in gilts. Materials and methods Estrus and ovulation were synchronized in 15 pubertal gilts. During their consecutive spontaneous estrous cycle the gilts were sonographically scanned daily and ovarian blood flow was determined by imaging perfused areas of the ovarian hilus and the ovarian tissue. Recorded video clips were then analyzed for the parameters perfused area (Amix), blood flow velocity (vmix) as well
