The __________ sign describes a loss of normal radiodense border secondary to a radiodense pathology positioned contiguous with the normal structure.
Silhouette sign
The __________ sign describes the finding that only structures seen in the POSTERIORLY located apex of the lung are seen above the clavicles.
Cervicothoracic sign
The ________________ sign is shown when air-filled bronchi are normally not seen because they are surrounded by air-filled lung. If the lung is filled with a water-based pathology the air filled bronchi will appear as radiolucent tubular densities transversing the lung
