ECHO Course
Which of the following determines lateral resolution ?
Pulse duration
Focus
Frame Rate
Frequency
Which of the following determines Axial resolution ?
Frame rate
Focus
Frequency
Velocity
Which of the following is the best way to compensate attenuation ?
Increase overall gain
Adjust compression
Adjust dynamic range
Adjust time gain compensation
Enhancement artefact is common when
Coupling gel is not used
An air filled structure is lying between the transducer and a strong reflector
Ultrasound encounters a strong reflector, such as gallstone or bone
Ultrasound passes through a low attenuating region, such as cysts and cardiac chambers
Acoustic shadow is
Due to complete absorption of ultrasound by tissues
Found distal to strong reflectors
Found only in obese patients
The anechoic region inside a cyst
All of these are criteria of quality for a good parasternal long axis view except
The septum must be as horizontal as possible
You should not visualize the apex of the left ventricle
You should see the aortic and mitral valves
You should see tricuspid valve
Which of the following is/are important sign(s)of cardiac tamponade ?
Large pericardial effusion
RV or RA collapsing
Dilated and non-collapsing IVC
B and C
All of the above
Which transducer is best for trans- thoracic echocardiography ?
Linear
Curvilinear
Phased array
Pedoff
The speed of ultrasound in soft tissue is an average of
5500 m/s
1450 m/s
1540 m/s
1250 m/s
IVC size and response to inspiration or sniffing are used to evaluate RA pressure on echocardiography. Which view is used to image the IVC ?
Parasternal short axis
Supra sternal
Apical 4 chamber
Subcostal short axis
The best ECG lead for monitoring during an echocardiogram is usually
Lead I
Lead II
Lead III
AVR - augmented leads
The ideal patient position for performing the parasternal and apical TTE views are
Supine
Right lateral
Left lateral
Prone
