POCUS Lung – Introduction to A-lines and B-lines
2022年11月16日 · B-lines, also referred to as comet tails, are vertical artifacts that appear as echogenic lines and extend from the pleural line into the lung parenchyma. They are created by discreet short path reverberation artifacts due to interstitial edema, increased fluid, or fibrosis in the interlobular septae.

B-lines form when interlobular septa and lung tissue thicken or fill with fluid. Thus, many clinicians have equated B-lines with “wet lung.” Remember, A-lines are horizontal while B-lines are vertical. In order to be sure you are seeing B-lines, make sure they have these following qualities (Lichtenstein, et al):

B-lines: B-lines are vertical lines that start at the pleural interface and extend to the bottom of the ultrasound screen, moving with the patient’s breath. Pathology Indicator: B-lines suggest the presence of interstitial fluid and are commonly associated with …
B-line (ultrasound) - Radiopaedia.org
Subpleural septal edema is postulated to provide a bubble-tetrahedron interface, generating a series of very closely spaced reverberations at a distance below the resolution of ultrasound which is interpreted as a confluent vertical echo which does not fade with increasing depth 3.

B Lines. Transient, hyperechoic vertical lines that extend from the pleura to the bottom of the screen at a depth of 16cm. Less than 2 B lines in any given region can be a normal finding; 3 or more B lines in any given region is pathologic (Wet Lung).

2017年10月31日 · The range of pulmonary findings on PoCUS includes the following: A-lines or horizontally oriented reverberation artifacts B-lines or vertically oriented bright lines extending to the sonographic window edge, which indicate loss of normal alveolar aeration (often secondary to pulmonary edema, infection, or contusion) (see Video 6)

2023年11月22日 · B lines are hyperechoic artifacts resembling laser beams that arise from the pleural line. They move in unison with lung sliding, reach the bottom of the screen, and erase the A lines.

The presence or absence of B-lines can help you narrow down the diagnosis in seconds: B-Lines present: 3+ B-lines in multiple lung fields, especially bilaterally: Pulmonary edema. Focal B-lines: Consolidation, mass . B-lines absent: A-lines + lung sliding: Asthma, COPD, PE. A-lines

2015年11月15日 · The differential for alveolar interstitial syndrome is broad, but can be narrowed based on the distribution of B-lines. Focal B-lines are the most non-specific findings of a consolidation (hepatization, dynamic air bronchograms, and the shred sign are more specific). Consider adding pulmonary hemorrhage to the differential for a focal B-line ...
