1

Is AP or PA view preferred and why

PA view is preferred

with AP view the scapula obscure lungs,
heart shadow magnified so can't be assessed properly
patient can't adequately inspire

2

Instructions to patient in CXR

Brace shoulders forward
Breath in and hold your breath

3

Why may AP view be used

patient can't stand (unwell, bed bound)

4

what can lateral CXR tell us and why is it rarely used

3D structure
rarely used due to CT scan availability

5

Steps before CXR

Confirm patients name, DOB, CHI
side marker- right way round?
Rotation- medial clavicles equidistant from spinous processes of vertebral bodies
Inspiration- at least 6 anterior ribs visible
Penetration-is there enough radiation

6

Dextrocardia

congenital abnormality
Heart points to right instead of left

7

Situs transvertus

congenital condition in which the major visceral organs are reversed or mirrored from their normal positions

8

which bronchus is it more likely for object to fall down

Right (straighter, more obtuse angle)

9

Draw all lung lobes, anterior and posterior
How many lobes per lung
Fissures

RUL, RML, RLL (3 lobes)
LUL, Lingula, LLL (2 lobes)

right- oblique and horizontal fissure
left- oblique fissure only

10

Presentation and Hx of miliary TB

recent travel
cough, night sweats, malaise
lots of tiny diffuse nodule on CXR

11

rash on shins
bilateral lymphadenopathy

Sarcoidosis

12

differences between right and left hila

left hila lies superior to the right

13

why are bronchi more visible on older patients

calcification

14

difference between right and left hemidiaphragm

right 1.5cm above left

15

diaphragm depression

pneumothorax, pleural effusion

16

diaphragm elevation

sub phrenic collection (blood ect) paralysis of c345

17

right middle lobe pneumonia appearance

right lower zone consolidation (anteriorly)
loss of right heart border
right hemidiaphragm still visible

18

Lingular pneumonia appearance

left lower zone consolidation (anteriorly)
loss of left heart border
left hemidiaphragm still visible

19

cause of lobar collapse

obstruction in lobar bronchus - lobe is no longer ventilated, loss of volume

eg tumours, aspirated food, mucus

20

Appearance of LLL collapse

anteriorly- triangle on inferomedial left lung along left oblique fissure
(google image)
reduced lung volume
loss of left hemidiaphragm

21

Appearance of LUL collapse

whole of left lung has veil like opacity
loss of left cardiac border
reduced left lung size
well defined lobar edge on lateral CXR

22

Appearance of RUL collapse

white RUL
horizontal fissure

23

loss of right cardiac border

pneumonia of right middle lobe

24

loss of right hemidiaphragm

pneumonia of right lower lobe

25

loss of left heart border

pneumonia of left lingula

26

D sign on CXR

Empyema (pleural space)

27

Bilateral pleural effusion

loss of costophrenic recess
obscured diaphragms

28

pleural effusion in CXR

fluid collects at lung bases
Mencius

29

ABCDEFG approach to reading CXR

Airways, Assess rotation, inspiration, penetration
Bones, body wall, breathing
Cardiac- cardiomegaly
Diaphragm
Effusion
Fields-lungs should be symmetrical
Great vessels

30

if CXR is normal with suspected PE

V/Q scan
