How to Read a Chest X-ray – A Step By Step Approach

This article is an try to give the reader guidance how to read a chest Xray and below are two methods. There is no perfect way to read an x-ray. However, the important message I would like to requite is, to adopt ane or the other approach, and to use the chosen approach consistently.

On all Xrays cheque the post-obit:

Check patient details
- First name, surname, date of birth.

Check orientation, position and side clarification
- Left, correct, erect, ap, pa, supine, decumbent

Check additional information
- inspiration, expiration

Check for rotation
- measure the distance from the medial end of each clavicle to the spinous procedure of the vertebra at the aforementioned level, which should exist equal

Check adequacy of inspiration
- Nine pairs of ribs should be seen posteriorly in lodge to consider a chest ten-ray adequate in terms of inspiration

Cheque penetration
- one should barely see the thoracic vertebrae behind the middle

Check exposure
- One needs to exist able to identify both costophrenic angles and lung apices

Specific Radiological Cheque Listing:

A - Airway

Ensure trachea is visible and in midline
- Trachea gets pushed away from abnormality, eg pleural effusion or tension pneumothorax
- Trachea gets pulled towards aberration, eg atelectasis
- Trachea normally narrows at the vocal cords
- View the carina, angle should be between 60 –100 degrees
- Beware of things that may increase this angle, eg left atrial enlargement, lymph node enlargement and left upper lobe atelectasis
- Follow out both main stem bronchi
- Bank check for tubes, pacemaker, wires, lines strange bodies etc
- If an endotracheal tube is in place, check the positioning, the distal tip of the tube should exist 3-4cm above the carina

Cheque for a widened mediastinum
- Mass lesions (eg neoplasm, lymph nodes)
- Inflammation (eg mediastinitis, granulomatous inflammation)
- Trauma and dissection (eg haematoma, aneurysm of the major mediastinal vessels)

B – Basic

Check for fractures, dislocation, subluxation, osteoblastic or osteolytic lesions in clavicles, ribs, thoracic

Spine and humerus including osteoarthritic changes

At this fourth dimension also check the soft tissues for subcutaneous air, foreign bodies and surgical clips

Caution with nipple shadows, which may mimic intrapulmonary nodules
- compare side to side, if on both sides the "nodules" in question are in the same position, then they are likely to exist due to nipple shadows

C - Cardiac

Check heart size and heart borders
- Appropriate or blunted
- Thin rim of air around the center, think of pneumomediastinum

Check aorta
- Widening, tortuosity, calcification

Check centre valves
- Calcification, valve replacements

Check SVC, IVC, azygos vein
- Widening, tortuosity

D – Diaphragm

Right hemidiaphragm
- Should be higher than the left
- If much higher, think of effusion, lobar collapse, diaphragmatic paralysis
- If y'all cannot meet parts of the diaphragm, consider infiltrate or effusion

If picture show is taken in erect or upright position you may see free air under the diaphragm if intra-intestinal perforation is nowadays

East – Effusion

Effusions
- Wait for blunting of the costophrenic angle
- Identify the major fissures, if y'all tin can see them more obvious than usual, so this could mean that fluid is tracking along the crevice

Check out the pleura
- Thickening, loculations, calcifications and pneumothorax

F – Fields (Lungfields)

Cheque for infiltrates
- Place the location of infiltrates by use of known radiological phenomena, eg loss of heart borders or of the profile of the diaphragm
- Remember that right eye lobe abuts the heart, just the right lower lobe does not
- The lingula abuts the left side of the heart

Place the pattern of infiltration
- Interstitial pattern (reticular) versus alveolar (patchy or nodular) blueprint
- Lobar collapse
- Look for air bronchograms, tram tracking, nodules, Kerley B lines
- Pay attention to the apices

Cheque for granulomas, tumour and pneumothorax

M – Gastric Air Bubble

Check correct position

Beware of hiatus hernia

Await for fee air

Look for bowel loops between diaphragm and liver

H – Hilum

Check the position and size bilaterally

Enlarged lymph nodes

Calcified nodules

Mass lesions

Pulmonary arteries, if greater than 1.5cm think almost possible causes of enlargement

Extended Radiological Check List – Lateral Pic:

A - Airway

Ensure trachea is visible and in midline
- Trachea gets pushed abroad from abnormality, eg pleural effusion or tension pneumothorax
- Trachea gets pulled towards aberration, eg atelectasis
- Trachea normally narrows at the vocal cords
- View the carina, angle should be between 60 –100 degrees
- Beware of things that may increase this angle, eg left atrial enlargement, lymph node enlargement and left upper lobe atelectasis
- Follow out both chief stem bronchi
- Check for tubes, pacemaker, wires, lines strange bodies etc
- If an endotracheal tube is in place, check the positioning, the distal tip of the tube should exist iii-4cm above the carina

Check for a widened mediastinum
- Mass lesions (eg tumour, lymph nodes)
- Inflammation (eg mediastinitis, granulomatous inflammation)
- Trauma and dissection (eg haematoma, aneurysm of the major mediastinal vessels)

B – Bones

Check the vertebral bodies and the sternum for fractures or other osteolytic changes

C – Cardiac

Bank check for enlargement of the right ventricle and correct atrium (retrosternal and retrocardiac spaces)

Trace the aorta

D – Diaphragm

Check for fluid tracking up, costophrenic blunting and the associated hemidiaphragm

East – Effusions

Bank check to see the fissures here likewise – both major fissures and the horizontal may exist plant in the lateral view

F – Fields

Cheque the translucency of the thoracic vertebrae in the lateral view, when there is a sudden change in transparency, then this is likely to be caused by infiltrate

Also effort to find the infiltrate that y'all call back you saw on the pa-motion-picture show to verify beingness and anatomical location

Pay special attention to the lower lung lobes

I would similar to close with a clarification of two important radiological findings, whose understanding is very useful for a right interpretation of breast x-ray findings.

The first is the silhouette sign, which tin can localise abnormalities on a pa-pic without need for a lateral view. The loss of clarity of a structure, such as the hemidiaphragm or heart border, suggests that there is next soft tissue shadowing, such every bit consolidated lung, even when the abnormality itself is non clearly visualised. The reason is, that borders, outlines and edges seen on plain radiographs depend on the presence of 2 adjacent areas of different density, Roughly speaking, merely four different densities are detectable on plain films; air, fatty, soft tissue and calcium (five if you include contrast such every bit barium). If 2 soft tissue densities lie adjacent, so they volition not exist visible separately (eg the left and right ventricles). If, however, they are separated by air, the boundaries of both will be seen.

The 2d important x-ray finding is the lung collapse. A collapse ordinarily occurs due to proximal occlusion of a bronchus, causing subsequently a loss of aeration. The remaining air is gradually captivated, and the lung loses volume. Proximal stenosing bronchogenic carcinoma, mucous plugging, fluid retention in major airways, inhaled foreign body or malposition of an endotracheal tube are the most common reasons for a lung collapse. Tracheal displacement or mediastinal shift towards the side of the plummet is often seen. Farther findings are elevation of the hemidiaphragm, reduced vessel count on the side of the collapse or herniation of the opposite lung across the midline.
