Pleural effusions refer to many different conditions of the pleura itself or to generalized diseases. Small amounts of fluid may not be apparent on conventional radiographs. Regarding the standard views the ventrodorsal projection shows the earliest signs of effusion, followed by the lateral recumbent. But even in these projections it is not possible to see a small amount of fluid. An additional lateral oblique view which you obtain by lifting the extremities seems to show small amounts of fluid more precisely and earlier than any of the standard projections.
