Label this chest x-ray 

 

  1. Trachea
  2. Hila 
  3. Lungs
  4. Diaphragm
  5. Heart
  6. Aortic knuckle
  7. Ribs
  8. Scapulae

2

Label this diagram

  • A - Right main bronchus 
  • B - Trachea
  • C - Aorta
  • D - Left main bronchus 
  • E - Carina 

 

3

What happens at the carina? 

The right and left main bronchus join 

4

Label this diagram

  • A - Costophrenic recess
  • B - Costophrenic angle 

 

5

What is this radiograph showing? 

A lobar collapse 

6

What is the radiological indicator of lobar collapse? 

Displacement of the horizontal fissure

7

When is the horizontal fissure displaced upwards? 

If there is volume loss of the right upper lobe (i.e. in a collapse)

8

When is the horizontal fissure displaced downwards? 

If there is volume loss of the right lower lobe (i.e. in a collapse)

9

What is this radiograph showing? 

Consolidation 

10

How can consolidation be identified on a radiograph? 

Compare the middle zones 

11

When is the lung said to be consolidated? 

If the alveoli and small airways fill with dense material 

12

What may consolidation be due to? 

  • Infection 
  • Fluid
  • Blood
  • Cells 

 

13

What may cause consolidation in infection? 

Pus 

14

When may consolidation due to infection occur? 

In pneumonia 

15

When may consolidation due to fluid occur? 

Pulmonary oedema 

16

When may consolidation due to blood occur? 

Haemorrhage 

17

When may consolidation due to cells occur? 

Cancer 

18

What happens on an x-ray if an area of the lung is consolidated? 

It becomes dense and white 

19

How can you tell if larger airways have been spared in consolidation of the lung? 

They are of relatively low density, and therefore appear blacker on a x-ray

20

What is the phenomenon whereby the x-ray of a patient with consolidation appears dense and white known as? 

Air bronchogram 

21

What is being shown in this diagram? 

A large, round, thick-walled lung cavity 

22

What has caused the cavity in this x-ray? 

Squamous cell lung carcinoma 

23

What is being shown in this x-ray? 

Pleural effusion

24

What is a pleural effusion? 

A collection of fluid in the pleural space 

25

Where does fluid gather in a pleural effusion? 

In the lowest part of the chest, depending on the patient's position 

26

What will be shown on an x-ray of a patient with pleural effusion if the x-ray is taken when the patient is standing? 

The pleural effusion will obscure the costophrenic angle/hemidiaphragm 

27

When is a pleural effusion difficult to see on a x-ray? 

When the patient is supine 

28

Why is a pleural effusion difficult to see on a x-ray when the patient is supine? 

Because the pleural effusion layers along the posterior aspect of the chest cavity 

29

How do pleural effusions appear on x-rays? 

Uniformly white, with the Meniscus sign 

30

What is the Meniscus sign? 

A concave area on the top of a pleural effusion, shown on x-ray
