chpt 6 study guide

if the line is above baseline on doppler flow this indicates?

• arterial flow

• venous flow

• portal venous flow

• towards the transducer

• away from the transducer

____ flow generally shows no pulsatile & has lower flow than _____ structures

• arterial & venous

• venous & arterial

• ivc & portal vein

• aorta & pancreas

where can you visualize the CBD in sagittal view ?

• towards the heart

• towards the pelvic cavity

• towards the liver elongated anterior to the portal vein

• towards the liver elongated anterior to the hepatic vein

• - the portal triad includes the, hepatic artery, portal vein & the bile duct

• - true or false

• true

• false

what type of waveform is this image representing and what vessel is displayed

• arterial & aorta

• venous & portal

• venous & IVC

• arterial & venous

what direction should blood flow be moving within the main portal vein ?

• it should be red and towards the liver because it is draining the GI tract into the liver

• it should be blue because it is draining the ivc into the liver

• it should be red because it is draining the ivc into the liver

• it should be blue because its draining the GI tract into the liver

Answer explanation

the portal vein is red in color doppler because it is draining the GI tract, gallbladder, spleen and pancreas into liver

• flow toward the transducer is positive or above the baseline

• - well defined borders w/ internal echoes

• - contains internal septatioins that may be thin (likely benign) or thick (likely malignant)

• loculated mass

• irregular borders

• isoechoic

• infiltrating

what type of waveform is this image representing ?

• venous

• arterial

• initial

• furthest

when can you visualize the CBD in transverse view ?

• at the pancreas head

• anterior to the pancreas body

• anterolateral to the pancreas head

• none of these

• - irregular borders are not well defined, poorly defined, or absent

• - true or false

• true

• false
