www.intechopen.com Lung Sonography 115 The probe should be in the cranio-caudal direction and the examiner needs to be aware of the position of the probe marker on the ultrasound screen for proper orientation. The first step is to identify the diaphragm as a curvilinear hyperechoic structure ...
Currently, cTBNA has been replaced by endobronchial ultrasound (EBUS)-guided TBNA: it includes an echobronchoscope (i.e., a bronchoscope with a convex probe at the distal end) and allows a real-time visualization of the lymph nodes and mediastinal vessels. Unlike cTBNA, EBUS-TBNA can diagnos...
Purpose Radial probe endobronchial ultrasound (RP-EBUS) accurately locates peripheral lung lesions (PLLs) during transbronchial biopsy (TBB). We performed an updated meta-analysis of the diagnostic yield of TBB for PLLs using RP-EBUS to generate recommendations for the development of ...
imaging tests like CT scan, thoracic X-ray, PET and biopsy techniques such as bronchoscopy, thoracentesis, endoscopic ultrasound and open biopsy. The prevalent
The acustophoresis aims at cell specific lateral displacement based on cells’ acoustic mobility [164]. The separation is performed by a horizontal and vertical pre-alignment of the cells suspended in a sample by ultrasound. It allows cells’ location in a regular flow velocity regime within a ...
European Expert Group recommendations state that at least five endobronchial/transbronchial forceps biopsies should be obtained and an additional five forceps biopsies or two cryo-biopsies could be considered; at least four endobronchial ultrasound/endoscopic needle aspiration passes per target needle are ...
During evaluation, the probe should be tilted as widely as possible, making small rotations along its main axis and tilting the tail of the probe to direct the ultrasound beam not only perpendicularly to the sagittal plane but also at oblique angles to avoid missing any areas. To better ...
Another important issue is the orientation of the probe. Scans are traditionally performed longitudinally, allowing for easy identification of the pleural line, but the visualization of the parenchyma may be limited by the size of the intercostal space. The reliability of a lung ultrasound (LUS) sc...
