Spectral Doppler ultrasound displays normal and abnormal signature waveforms unique to each vessel, which are critical for sonographers and radiologists to recognize in clinical examinations.
This review provides an overview of the physics and clinical application of spectral Doppler ultrasound for evaluating normal and abnormal blood flow in various major vessels.
Enhances sonographer recognition of spectral Doppler waveforms; leaves open prospective validation of diagnostic impact in cardiology.
Doppler ultrasound is routinely used in the clinical setting to evaluate blood flow in many major vessels of the body. Spectral Doppler is used to display the normal and abnormal signature waveforms that are unique to each vessel. It is important for the sonographer and the radiologist to recognize both what is normal and what is abnormal in a spectral Doppler display. In this review, we briefly explain the physics behind Doppler ultrasound and some of the most common mathematical equations applied in a routine clinical examination. We also describe and demonstrate normal versus abnormal spectral Doppler signature waveforms of vessels in the neck, abdomen, pelvis, and fetus.
