- Linear High Frequency Probe
- Normal lung sliding is seen.
- The pleura is the echobright shimmering line that has the appearance of ants marching.
- Ribs and rib shadows on either end of the clip.
- Intercostal muscle is seen between the ribs.
- Z-lines or comet tails appear to arise from the pleural line. These are artifacts.
- Linear High Frequency Probe
- Lung sliding is absent. The pleura is static and does not slide at all.
- Linear High Frequency Probe
- A lung point is seen. There is lung sliding present on the right side of the clip.
- Lung sliding is absent on the left side of the clip.
- This is virtually diagnostic of pneumothorax.
- Curvilinear Low Frequency Probe
- B-lines are laser like artifacts that extend from the pleural surface all the way to the bottom of the screen.
- They indicate the presence of interstitial oedema.
- It can be normal to have < 3 B-lines per intercostal space.
- Curvilinear Low Frequency Probe
- Lung consolidation is seen.
- The boundary between normal lung and consolidated lung has a jagged appearance. This is called the shred sign.
- Within the area of consolidation, there are multiple echobright spots that likeley represent air bronchograms. This is called the tissue sign.
- Curvilinear Low Frequency Probe
- There is a pleural effusnoi present, seen as an anechoic area above the diaphragm.
- There is also fluid present below the diaphragm. This is ascitic fluid.
