Flashcards in Cardiovascular Imaging Deck (10):
1

stroke volume equation

SV = EDV - ESV

2

cardiac output equation

CO = SV x heart rate

3

ejection fraction equation

EF = SV/EDV

4

What are the major features to look at in a cardiac image?

overall anatomy

cardiac chamber size

thickness of myocardium

narrowing of coronary arteries

state of cardiac valves

disease of great vessles

disease of pericardium

5

echocardiography

assess cardiac structure and function using ultrasound technology

no ionizing radiation

6

principle uses of echocardiography

assessment of left and right ventricular size and function

assessment of left ventricular wall motion

assessment of myocardial thickness and mass

assessment of left atrial size

assessment of valvular structure and function

estimation of pulmonary artery pressure

assessment of aortic and pulmonary artery diameter

7

cardiac magnetic resonance

produces anatomic and functional images using energy from a high-strength magnetic field

resulting images have higher resolution than echo or nuclear techniques

no ionizing radiation

8

principle uses of cardiac magnetic resonance

assessment of cardiac and great vessel anatomy

assessment of left and right ventricular size and function

assessment of myocardial scarring and viability

9

cardiac computed tomogrpahy

noninvasive method to provide high resolution images of heart and blood vessels

uses ionizing radiation

10

principle uses of cardiac computed tomography

assessment of cardiac and great vessel anatomy

assessment of left and right ventricular size and function

assessment of coronary artery calcification

assessment of coronary artery anatomy and severity of atherosclerotic obstructions
