Doppler US of helical flow in the portal vein. | RadioGraphics

01.09.1995 · In helical portal venous blood flow, the usual laminar flow in the portal vein is replaced by a spiral. This changes the color Doppler ultrasound (US) appearance to one of alternating or parallel red and blue bands. Duplex US may appear to show hepatopetal, hepatofugal, or simultaneous bidirectional flow depending on placement of the cursor within …

13.05.2015 · When Doppler US is performed in conjunction with gray-scale US, it can yield valuable additional information, facilitate diagnosis, and direct further imaging and treatment. In addition to its use as a first-line imaging modality for noninvasive vascular imaging, Doppler US can also be used to define findings seen at gray-scale US or other imaging modalities and can …

Doppler US of the Liver Made Simple - RSNA Publications Online

Doppler ultrasonography (US) is usually the first-line modality for evaluat- ing flow in native liver vessels and transjugular intrahepatic portosystemic shunts (TIPS). Waveforms, which represent flow in each of the major ves-sels and in TIPS, have been well described. The appearance of these wave-forms should be recognized, and the mechanisms behind their generation should be …

Recent Variceal Bleeding: Doppler US Hepatic Vein Waveform ...

01.08.2006 · Hepatic vein Doppler waveforms were classified as triphasic, biphasic, or monophasic. Severe portal hypertension was defined as an HVPG of more than 15 mm Hg. In a subgroup of 21 patients, changes in hepatic vein waveform and HVPG were evaluated after intravenous administration of 2 mg of terlipressin. Statistical analyses were performed with ...
