Abstract: The nodular pattern is characterised by the presence of multiple nodular opacities with a maximum diameter of 3 cm. A nodule with a diameter less than 1 cm can be defined as a small nodule, whereas a nodule larger than 1 cm is often called a large nodule (Grenier et al. 1991). The term “micronodule” usually refers to nodules no larger than 7 mm in diameter (Austin et al. 1996; Collins 2001). The term “miliary pattern” indicates the presence of multiple small (1–3 mm) micronodules with sharp contours distributed in a major part of the lungs (Andreu et al. 2002; Lee et al. 1999). Generally, the nodules in the nodular pattern range from 1 mm to 1 cm. Larger nodules are often the result of the fusion of several small nodules.
