==Basic screening==
One method uses an alphabetic order:
*'''Airways''': Any shift to the side?
*'''Bones''': Check for obvious fractures
[[File:Cardiothoracic ratio.jpg|thumb|220px|Cardiothoracic ratio =
<math>{MRD + MLD \over ID}</math>

<br>MRD = greatest perpendicular diameter from midline to right heart border
<br>MLD = greatest perpendicular diameter from midline to left heart border
<br>ID = internal diameter of chest at level of right hemidiaphragm]]
*'''Cardiac''': Check both cardiothoracic ratio and any dilation of blood vessels.
*'''Diaphragm''': Check for any pleural fluid
*'''Edges''': Check for pneumothorax
*'''Fields''': Any lung consolidations
[[File:X-ray of hiatal hernia, annotated.jpg|thumb|200px|Hiatal hernia.]]
*'''Gastric''': Whether there is any apparent hiatal hernia
*'''Hili''': Prominence, such as by lymphadenopathy
*'''In lateral image''': as a reminder to check the lateral projection, if available, mainly in the lung fields, for any apparent pathology
