Webb21 feb. 2024 · Complete torsion occurs when the testis twists 360° or greater, usually leading to absence of intratesticular flow on color Doppler exam; however sometimes the flow is preserved or decreased. Intermittent torsion is defined as sudden onset of unilateral testicular pain of short duration with spontaneous resolution. Webb1 dec. 2009 · Possible causes of slow venous flow in the IJV include asymmetry of flow from the ana- tomical variations described above, incompetence of the jugular valve, increased central venous pres- sure from congestive heart disease or tricuspid valve regurgitation, and increased intrathoracic pressure from pulmonary hypertension or … WebbDoppler ultrasonography is used to evaluate characteristics of blood flow: its presence or absence, direction, velocity, and character (laminar versus turbulent flow). The 4 Doppler techniques used in ultrasonography are continuous-wave, pulsed-wave, power, and color Doppler, which are divided into spectral displays and color modes. how many dollars is 1800 pounds
