indications for chest xray

eval of symptomseval of physical signseval of placement of central linesscreen for pneumothorax after lung biopsy, central line placement, and pacemaker placementetc

factors that determine shadow brightness on xray

1. Density - denser things block more x-rays & appear whiteRadiolucent (black) <-> Radiopaque (white)Air <- Fluid and soft tissue -> Bone -> Metal2. Thickness - thicker will be whiter3. Duration of exposure - errors in xray exposure
