Basics of CXR Reading PA & lateral is ONE UNIT Normal vs. no active disease Ask for old x-rays Focus on other areas too It is a photograph Describe what you see and not what you feel It is a comparative study: two x-rays; two sides Apples to apple: technique, view, exposure, position, tilt Black/white/gray Study of contrasts Lung Space Unit Predominant pattern i.e. nodular, linear, reticular, honeycomb Lateral view When helpful? When is it a waste? When not needed? 3
