Spectral Doppler is an ultrasound technique for image display, consisting of Pulse Wave Doppler (PW) and Continuous Wave Doppler (CW). Doppler echocardiography is a vital diagnostic tool for the clinical evaluation of cardiac patients, providing a reliable means to obtain images of the heart (using ultrasound waves) for assessing the severity of blood flow (or, velocity), blood flow obstruction, and other cardiovascular disorders.
Differences Between PW Doppler and CW Doppler
PW Doppler is primarily used to assess blood flow/velocity across valves or vessels, to evaluate cardiac function, and/or to calculate flow within a small window of space.
Two-dimensional echocardiography assists with obtaining usable data (for example, heart chamber size; evaluation of diastolic and/or systolic function; quantitation of intracardiac shunts), which can be measured to identify cardiac conditions, measure cardiac output (CO) and regurgitant volumes.
