3. Different tissues in body absorb X-rays at
different extents:
• Bone- high absorption (white)
• Tissue- somewhere in the middle absorption (grey)
• Air- low absorption (black)

8. •Looks whether is well centralized or not,...check for medial
end of Clavicle ...both should be at equil level from spine.if
not then it is difficult to comment about ardiomegalyc,
mediastinal deviation.. whichever one end is more close to
spine-----mediastinum is deviated on that side.
•check for right and left side
•look for exposure....if u see for spinal process then its well
exposed...if over exposed then it looks translucent( like
emphysema)
•Looks for cardio and costophrenic angle...all should
be acute...if not then it is abnormal....also look for
Diaphragmatic contour...if flattened ---then probably some
lung disease...

9. •check Apical area ...esp behind the Clavicle for TB lesion then
check lower lung filed for all 4 angle,,
•check trachea...and trace it upto carina...should be patent
•Cardiac: Let side border is made by Aortic knucle ,
pulmonary conus, left atrium and Lt ventricle while right side
border is made by SVC and right atrium
•Vascular markings: Lower lobe vessels are more prominent
compare to Upper lobe coz of Gravity...If not then Cardiac
problem.. Right side vessels look more prominent than left
side.
