ECG110 Wk #1 Detailed Anatomy Flashcard

Front

What is the PSAX MV level in echocardiography?

Back

The PSAX MV level (Parasternal Short Axis Mitral Valve level) is a specific view obtained during an echocardiogram that allows visualization of the mitral valve and surrounding structures.

Front

What does TGC stand for in ultrasound imaging?

Back

TGC stands for Time Gain Compensation, which are controls used to adjust the brightness of the ultrasound image at different depths.

Front

What does RVIT stand for in echocardiography?

Back

RVIT stands for Right Ventricular Inflow Tract, which is a view used to assess the inflow of blood into the right ventricle.

Front

What type of graph is used to display M-Mode images?

Back

M-Mode images are displayed using a time-depth graph, which shows how the depth of structures changes over time.

Front

What is attenuation in the context of ultrasound?

Back

Attenuation refers to the reduction in the intensity of a sound wave as it travels through a medium, such as body tissues.

Front

What is the purpose of using TGC controls in ultrasound imaging?

Back

TGC controls are used to manually adjust the image display to compensate for variations in tissue density and improve image quality.

Front

What is the significance of the RVIT view in echocardiography?

Back

The RVIT view is significant for evaluating right ventricular function and assessing conditions such as tricuspid regurgitation.

Front

How does a time-depth graph differ from other types of graphs in ultrasound?

Back

A time-depth graph specifically plots the depth of structures against time, allowing for the visualization of motion and changes in depth.

Front

What are the common causes of attenuation in ultrasound?

Back

Common causes of attenuation include absorption, scattering, and reflection of sound waves by tissues.

Front

What is the role of the mitral valve in the heart?

Back

The mitral valve regulates blood flow between the left atrium and left ventricle, preventing backflow during ventricular contraction.
