WebUltrasound technology has advanced significantly in recent years, although application of newer imaging protocols has been slow to catch on. With implementation of modern protocols, ultrasound is highly sensitive and accurate for the … WebUltrasonography-assisted fine-needle aspiration and/or cutting-needle biopsy of extrathoracic lymph nodes, and lesions arising from the chest wall, pleura, peripheral lung and mediastinum are safe and have a high yield in the of hands of chest physicians.
WebApr 29, 2024 · Most ultrasound waves are reflected at the pleura in an air-filled lung owing to the acoustic impedance mismatch at the air and soft-tissue interface that results in a hyperechoic pleural line ( 53 ). Thus, the air-filled lung parenchyma cannot be directly visualized at US. WebUltrasound has been the primary tool used to screen for TIPS stenoses because it is non - invasive, readily available, and relatively low cost compared with other imaging modali-ties. However, many different ultrasound pa-rameters have been used to assess patency, with variable results. Flow velocities in the TIPS represent the primary parameter.
