Figure 1
Sagittal MIP images acquired from a soft tissue kernel in three different patients with micronodular lung disease. The fissures are indicated with blue arrows.
A. Perilymphatic distribution. The fissures are affected by the micronodules, more so than many parts of the parenchyma. Also note the patchy distribution of the nodules in the lungs.
B. Centrilobular distribution. The fissures are not affected by the micronodules, as the nodules are located in the center of the secondary pulmonary lobule, away from the fissure.
C. Random distribution. The fissures are affected by the microndules, but not more than the lung parenchyma. The nodules are evenly distribution throughout the lung and the fissure.
