Lung ultrasound diagnosis uses focused, pattern-based scans, whereas quantification requires standardized acquisition across multiple zones.
-
2
Quantitative lung ultrasound supports monitoring and prognostic stratification, with stronger evidence for prognosis than for treatment guidance.
-
3
The recommendations distinguish basic signs, supplementary features for differential diagnosis, and clinical interpretation integrated with other information.

5
In heart failure, B-line counts predict rehospitalization and mortality, while evidence that ultrasound-guided dialysis fluid removal improves survival remains lacking.
