CSC CSC Diagnostic Imaging & Procedures

Question 1

In echocardiography, the parasternal long axis view best assesses:

Accepted Answer

Mitral valve, aortic valve, left ventricle, and aortic root

Answer

Right ventricular outflow tract only

Answer

Tricuspid valve and inferior vena cava

Answer

Pulmonary veins and left atrial appendage

Question 2

Doppler echocardiography measures:

Accepted Answer

Blood flow velocity and direction

Answer

Myocardial thickness and mass

Answer

Valve leaflet thickness

Answer

Pericardial effusion volume

Question 3

A stress echocardiogram is used primarily to detect:

Accepted Answer

Inducible myocardial ischemia

Answer

Pericardial disease

Answer

Valvular stenosis at rest

Answer

Atrial septal defects

Question 4

Transesophageal echocardiography (TEE) is preferred over transthoracic echocardiography (TTE) for evaluating:

Accepted Answer

Left atrial thrombus and aortic dissection

Answer

Pericardial effusion

Answer

Right ventricular size

Answer

Pulmonary hypertension

Question 5

Color flow Doppler in echocardiography encodes blood flow direction as:

Accepted Answer

Red = toward transducer, Blue = away from transducer

Answer

Red = away from transducer, Blue = toward transducer

Answer

Green = normal flow, Red = turbulent flow

Answer

Yellow = stenotic flow, Blue = regurgitant flow

Question 6

The E/e' ratio in tissue Doppler imaging is used to estimate:

Accepted Answer

Left ventricular filling pressures (diastolic function)

Answer

Systolic function

Answer

Right ventricular systolic pressure

Answer

Aortic valve area
