WebThe mean linear intercept (L (m)) can be used to estimate the surface area for gas exchange in the lung. However, in recent years, it is most commonly used as an index for characterizing the enlargement of airspaces in emphysema and the associated severity of structural destruction in the lung. WebLung surface area, mean linear intercept and fractional volume findings. Surface area measurements were made in all lung specimens using tissue morphometry, and the quantitative results are shown in table 2 ⇓. As expected, lung tissue from patients with emphysema demonstrated significantly lower surface areas compared with normal lungs.

WebNational Center for Biotechnology Information WebTo assess the extent of emphysema, nearly all studies that have attempted to quantify histologic sections have used the mean linear intercept (MLI) or mean airspace chord length ( L m). The MLI and L m differ by the mean thickness of the alveolar septa, but both are inversely proportional to the parenchymal surface/volume ratio ( 3 ).

WebNov 9, 2024 · Mean linear intercept (MLI) is a measure of morphometric change based on serial measurements of the lung using test lines, but cannot be directly interpreted as a measure of alveolar size.
