*
Suzuki classification17 for adenocarcinoma of the lung includes.
Type 1: Pure (simple) GGO.
Type 2: Semiconsolidation (an area of intermediate homogeneous increase in density).
Type 3: Halo (area consisting of solid part and surrounding GGO halo).
Type 4: Mixed (an area consisting of GGO and solid part having air-bronchogram).
Type 5: Solid pattern with GGO.
Type 6: Solid pattern.
GGO indicates ground-glass opacity.
