High-risk patterns and Low-risk patterns
Six LUS imaging patterns were found in these late preterm and term
infants immediately after birth (Figure 2). These patterns were
categorized as ”high-risk” and ”low-risk”. The low-risk patterns, which
indicate a lower likelihood of lung issues, include the ”pure A-line”
pattern, ”scarce discrete B-line” pattern, ”moderate discrete B-line”
pattern, and ”abundant discrete B-line” pattern. In fact, the three
kinds of ”discrete B-line” patterns can be easily discerned when
performing LUS, and there was no need to identify each of them, as they
were all significantly different from the ”pure A-line” patterns and
high-risk patterns, and they are less likely to be a sign of lung
issues. High-risk patterns included the ”coalesced B-line” and
”consolidation” patterns.
