Lung ultrasound and B-lines quantification inaccuracy: "B sure to have the right solution". The authors paint an intriguing outline for the future of lung ultrasound where computer-based analyses provide a reliable and less operator-dependent method of measurement. As discussed, B-lines are dynamic lung ultrasound artefacts that are easily identified and discerned from a non-pathological ultrasound image, but are increasingly difficult to count when numerous and confluent.

Lung ultrasound (LUS) is a fast, non-invasive bedside tool for detection and quantification of pleural and parenchymal pathology through sonographic artifacts [[1]]. In short, images were acquired in 27 patients admitted with respiratory pathology and rated by five independent raters, all experienced and certified for LUS, to assess reproducibility between linear, cardiac, and abdominal transducers. This seems to be intuitive, as among other technical factors, frequency, and thus image quality, but also transducer width and therefore area of lung tissue visualized, differs [[8]].
