Transcript of CXR imaging
Rania Ma’adat
What to check first
Name, Age, Date , sex
Clinical info. History “not always”
Technical factors:
1-Marker
Marker to determine
right or left side =
direction of the
picture
2- Centralization
The distance between
the medial end of the
clavicle and the
spinous processes
“Should” be equal
bilaterally.
3- Full inspiration
We count , 9 posterior ribs, 7 anterior ribs
6th rib is perpendicular to the diaphragm
ExposureThe retro cardiac vertebrae are just visible
Lung zones
Upper
Middle
Lower
any lesion is said
to be located in
one of these zones
abnormalities
Remember that:Bone is white on X-rayAir is blackTissue is grey
Abnormal findings are:
Consolidation
Collapse, hyper inflation
Pleural sac abnormality
Bone abnormality
Consolidation
Any abnormal white batches except those of normal anatomy slide 2 is said to be consolidation.
1- fibrosis
2- mass
3-tracheal shift “ not mediated” slide 5, Aoticaneurysm, esophageal problem
4- lymph node enlargement
5- pneumonia “ at the base of the lung”
etc
Right lung
pneumonia
Right lung mass
Aortic aneurysm
Multiple nodules=
Lung metastases
2- collapse
Absent part of
the lung usually
with obstruction
normal lung
tissue but
missed part
Hyper inflation
Main sign is flat
diaphragm
Pleural abnormality
We have visceral and parietal pleura
accumulation of air, fluid, blood or pus
can lead to CXR abnormality.
1- Pneumothorax: Air “black”
2- Pleural effusion: Fluid “white”
3- Hemothorax: blood “white”
4- Empyema: pus “white”
Plueraleffusion
No air bronchogram
No costophrenicangle
Upper border of fluid is concave
Hemopneumothorax
Similar to
pnuemothorax but
the upper border is
flat cuz of air
pneumothorax
Bone abnormalities Ribs fracture
Notes:
Air under diaphragm is always
abnormal! The main cause is bowel
perforation
