How should we scan lung anteriorly or posteriorly and longitudinal or transvarse plane which is best plz guide

how do you differentiate mirror artifact from hepatization?

This can be difficult. Keep in mind that in order to have mirror artifact the ultrasound beam must travel through solid organ (or heart) before encountering the diaphragm (lung is where most mirror artifact occurs). If it occurs at the top of the screen, without passing through solid organ, then this is likely hepatization. Also you can look for the spine sign but this would require the entire lung lobe to have hepatization.

I'm confused here, Whats the difference between those B lines and a ring down artefact??

B-lines is the name of this type of short path reverberation artifact that happens in the lung/aveoli. If it is in the bowel for example then it's called a ring down artifact (due to air/fluid in the bowel). Both are short path reverberation artifacts. Additionally there are long path reverberation artifacts. In the lung, for example, these are called A-lines. If it is created by a piece of metal, glass, or similar inside the body this would be a type of reverberation artifact that I've often heard people refer to this as ring down artifact (though this more likely reflects long path reverberation artifact). Does that help?

How can you see lung cancer ?

I'm not sure that this has been well defined and have limited experience as I often don't diagnosis this in the Emergency Department with ultrasound. Here are some characteristics that have been described but I am unaware of any well defined criteria. If that is your concern another imaging modality should be used. Malignant effusion - complex fluid (internal echoes) and/or complex effusions (septate effusion). Adjacent air bronchograms. Absence of lung sliding. An anything from well defined mass to a poorly defined mass. Keep in mind that if a cancer does not come in contact with the pleural line (where the visceral and parietal pleural come in contact) you won't be able to see the mass.
