2. • Air way – trachea central
• Bones –normal
• Cardiac- right cardiac border is obscured
• Diaphragm- right side diaphragm not visualised
• Extra thoracic soft tissue- normal
• Field-homogenous opacity noted in the right lowerzone with a
horizontal upper margin,hypertransradiancy noted in the
upper and mid zone with absent bronchio vascular markings,
outer border of collapsed lung can be seen,hyper inflation of
left lung
• Fissure –not visualised
• Gastric bubble – not seen
• Hilum- collapsed right hilum, left hilum normal
• Mediastinum- central

4. • Air way – trachea central
• Bones –normal
• Cardiac – left lower cardiac border not visualised
• Diaphragm- left side not visualised
• Extra thoracic soft tissue- normal
• Field- homogenous opacity noted in the left
lower zone extending higher up towards the
lateral side
• Fissure – not visualsed
• Gastric bubble
• Hilum- prominent right hilum
• Mediastinum- normal

7. LATERAL CHEST XRAY
INDICATIONS
• Localize a lesion seen on frontal xray
• To clarify lobar collapse/consolidation
• To explore a retrosternal or retrocardiac
shadow
• To confirm presence of encysted fluid in the
oblique fissure

8. LATERAL VIEW
 Patient to be turned to bring side of
investigation in contact with the
cassette
 Median sagittal plane is parallel to the
cassette
 Arms are folded over the head or
raised above the head
 Mid axillary line coincident with
middle of the film
 Cassette is adjusted to include apices
and lower lobes to the level of 1st
lumbar vertebrae

9. CENTERING
 Horizontal ray at right angle to the middle of the
cassette at the mid axillary line

10. • Airways
• Bony cage
• Cardia and mediastinum
• Diaphragm and costophrenic angle
• Fissures

11. Airways
• Trachea
• Left upper lobe
bronchus
• Right upper lobe
bronchus

12. • Trachea appers as a
radiolucent structure
• It tapers as it comes down
• Right upperlobe bronchus
and left upper lobe
bronchus appears as super
imposed on the trachea
• Higher one right upper lobe
bronchus and the lower
one the the left upper lobe
bronchus
• Some times only left main
bronchus is only visualised

13. Blood vessels
• Aorta
• Hilar vessels
1. Right pulmonary
artery
2. Left pulmonary
artery

14. Aorta look for calibre

15. • Seen as
structures
sandwiching
the major
airway
RPA- anterior
LPA- posterior

16. Bones
• Sternum
• Ribs
• Thoracic
vertebrae-look
for collapse

17. Cardiac
• Right ventricle
• Left ventricle
• Left atrium

18. Diaphragm
Right -Curvilinear dense
structure all the way from
anterior to posterior, can be
traced entirely
Left- from posterior to the
cardiac shadow
Left diaphragm will be closely
associated to gastric bubble

19. Fissures
• Oblique fissure
• Horizontal fissure

20. • Both commence
posteriorly at T4/5
level passing through
hilum
• Left is steeper
finishes 5cm behind
anterior costophrenic
angle
• Right ends just
behind the angle
OBLIQUE FISSURE

21. Retro sternal and retro cardiac areas

22. • Opacity in retrosternal area- anterior
mediastinal mass lesion , right ventricle
enlargement
• Retrocardiac opacity- lung lesion , enlarged
right ventricle
