Duplex ultrasonography combines:
High-Yield Explanation
Ans. B. B-mode imaging and pulse-wave doppler examinationAn objective assessment of the severity of disease is obtained by noninvasive techniques. These include digital pulse volume recordings, doppler flow velocity waveform analysis, duplex ultrasonography (which combines b-mode imaging and pulse-wave doppler examination), segmental pressure measurements, transcutaneous oximetry, stress testing (usually using a treadmill), and tests of reactive hyperemia.
