Ultrasonography is the use of sound waves to generate medical diagnostic images. The portability, cost-effectiveness, and non-invasive nature of ultrasound have contributed to its widespread use over recent decades.[1] Vascular ultrasound is a generalized term that includes venous duplex and Doppler sonographic assessment of myriad arterial and venous pathology, most commonly including ...
27 mar 2023 · A normal spectral arterial waveform is triphasic, consisting of a sharp systolic upstroke, early diastolic flow reversal, and late diastolic return to antegrade flow. The waveform should be sharply outlined.
In contrast, normal and abnormal are interpretative terms and depend on the specific vessel, vascular bed, pathology, and other factors. Each of the aforementioned waveform descriptors may be normal or abnormal, depending on the clinical setting (e.g. a monophasic waveform is normal in a renal artery and abnormal in a brachial artery).
2 sty 2020 · This includes a study of normal waveform patterns and characteristic changes that occur with pathologic states. Important tips are given for recognizing Doppler spectral features that are essential for the diagnosis of arterial stenosis and occlusion.
6 lut 2023 · Duplex ultrasound of the peripheral venous system is an easily accessible and reliable method of diagnosis, evaluating the extent and severity of the disease and monitoring progression and planning treatment.
