Live pulmonary endoscopy
Transthoracic ultrasound
AIMS: Transthoracic ultrasound is a helpful tool for investigating clinical problems such as
suspected pleural fluid, white hemithorax, atelectasis, empyema, and diaphragm function problems.
This session will demonstrate some of the most common investigations that are performed such as:
pleural effusion, white hemithorax, empyema, peripheral located lung tumor, mesothelioma.
TARGET AUDIENCE: General pulmonologists and residents.

Oxford
Pleural
Unit What is ultrasound
• A longitudinal wave - particles move in
the same direction as the wave.
• A succession of rarefactions and
compressions transmitted due to elastic
forces between adjacent particles
9
Oxford
Pleural
Unit What is Ultrasound
• Audible sound has frequency 20 Hz to 20 kHz
• Most diagnostic ultrasound has frequencies in
range 2-20 MHz
10
Oxford
Pleural
Unit Important equation!
• Frequency of oscillations inversely
proportional to wavelength
• f = c/ (c ≈ 1540 m s-1 in soft tissue)
• Diagnostic ultrasound of 2-20MHz,
wavelength• = approximately 1 - 0.1 mm in tissue
11
Oxford
Pleural
Unit Generation of Ultrasound
• US generated by piezoelectric crystal
• Commonest material is lead zirconate titanate
(PZT).
• Electric field applied:
• crystal rings at a resonant frequency
• determined by its thickness
• Same or similar crystal used as receiver:
• produces electrical signal when struck by the returning
ultrasound wave

Unit Speed of ultrasound in tissue
• Speed of US in tissue depends on:
• Stiffness
• Density
• Stiffer material (more solid) transmits
ultrasound faster

Unit Interaction of US with tissue
Ultrasound which enters tissue may :
• Transmit
• Attenuate
• Reflect
16
Oxford
Pleural
Unit Attenuation
• If particles in a tissue are small enough:• Move as a single entity
• Transmit sound in an orderly manner
• Coherent vibration
• Sound
• If large molecules are present:• Chaotic vibration
• Heat
• Loss of coherence loss of ultrasound energy
• Alter with gain control on machine
17

UnitGain too high
18
Oxford
Pleural
Unit Gain reduced
19
Oxford
Pleural
UnitAbsorption of
ultrasound / gain
• Absorption of ultrasound:
• Lower tissues return less ultrasound
• Some absorbed as heat
• Some reflected/refracted out of field of probe.
• To ensure a uniform picture
• (so deeper areas not darker)
• Use Time Gain Compensation (TGC).
• TGC:
• Applies progressively increasing amplitude to later
echoes in proportion to their depth
• i.e differential amplification
20
Oxford
Pleural
Unit TGC
• TGC can be varied by users
• Used to compensate for artefactual increased
brightness
• Beware previous user adjusting TGC controls
21
Oxford
Pleural
Unit TGC incorrect
22
Oxford
Pleural
Unit TGC corrected
23
Oxford
Pleural
Unit
• Absorption proportional to ultrasound
frequency
• Higher frequency probes:
• Smaller depth penetration
• Better resolution
• Many US machines allow user to alter
frequency up to maximum/minimum allowed

Reflection
Importance of Reflection:• Allows generation of the ultrasound signal
• Leads to loss of ultrasound signal
• Determines the appearance of tissue
• Can cause artefacts
27
Oxford
Pleural
Unit Reflection
Reflection occurs when:
• Ultrasound crosses an interface between two tissues with
different impedance
• Amount depends on difference in impedance
• Ultrasound which is not reflected:
• Continues
• Is used to image deeper structures

2. Cannot see through aerated lung
3. Cannot see through bone
32
Oxford
Pleural
Unit Artefacts
Mirror artefact• Occurs at smooth curved surfaces eg
diaphragm
• Reflection occurs
• Projects image of organ under diaphragm eg liver, above diaphragm
• Reflections of liver into chest can give false impression consolidated lung
33
34
Oxford
Pleural
Unit Acoustic shadowing
• Artefact:• Causing shadowing behind certain structures
• Prevents user seeing beyond them
• Caused by absorption or reflection
• Occurs at fibrous tissue eg scars and fat (eg fatty liver)
35
Oxford
Pleural
Unit Fatty liver
36
Oxford
Pleural
Unit Gas shadows
• Proportion of incident US reflected
• Unable to continue through the tissue for imaging
• At gas-tissue interfaces:• Almost all US is reflected
• Lung:• Clean shadow
• Bowel gas shadows:• ‘Dirty shadows’
• Partly filled by reverberant echoes due to multiple gas-tissue reflectors

• High Hz (7-12MHz) better for detail (e.g. small parts)
• Shape of transducer:• Linear
• Curvilinear
• Small footprint
• Machines much the same for standard use

Oxford
Pleural
Unit SummaryKey points:
• US relies on sound creation, reflection and detection
• In tissues, US can transmit / attenuate / reflect
• Decrease attenuation by increasing power (gain)
• Higher frequency, better penetration
• Interface of tissues determines how much is reflected
• Artefacts:• Mirror• Shadowing
58
Oxford
Pleural
Unit Ultrasound tips
• Use highest frequency for necessary depth penetration
• Use tissue harmonics for larger patients
• Try moving patient into different positions eg to move ribs apart/move bowel gas out of way
• Use ‘optimise’ button
• Reduce size of sector for improved resolution
• More jelly and press harder

Key Issues in training:
• Friendly radiologist
• Regular scanning time
• Familiar with machine

Key issues in practice:
• Know your own limits
• Access to experience if required
126
WHEN TO ASK FOR HELP…
• Radiologist more skilled in all aspects of US
• Radiologist has access and understanding of

• MUST know own limits
127
SUMMARY POINTS
• Evidence suggests thoracic US improves safety and
accuracy of pleural procedures
• Know its limitations and, more importantly, your limitations
• Use of US in untrained/ inexperienced hands provides false confidence and may be harmful – access to machines with level 1 certificate or under supervision only
• Radiologists are highly trained in ultrasound – work closely and maintain a mentor after achieving basic training
