Screen Orientation, Direction of Flow, and Anatomy

UT 302 - Abdomen 1

label each number and determine the imaging plane

1. superior

2. anterior

3. inferior

4. posterior

longitudinal image

label each number and determine the imaging plane

1. right or medial

2. anterior

3. left or lateral

4. posterior

transverse image

T/F: we can only tell flow direction in long/sag vessel orientation, not transverse

true

describe the blood flow occurring in this image

• the anterior vessel is red, and red is on the bottom of the color bar, which means that blood is flowing away from the transducer

• the posterior vessels are blue, and blue is on the top of the color bar, which means that blood is flowing toward the transducer

describe the blood flow occurring in this image

• when imaging the carotid artery, we are above the heart, so

  • blood flowing from inferior to superior is going away from the transducer/heart

  • blood flowing from superior to inferior is going toward the transducer/heart

• when imaging the SFA/SFV, we are above the heart, so

  • blood flowing from inferior to superior is going toward the transducer/heart

  • blood flowing from superior to inferior is going away from the transducer/heart

where is the color detector/transducer in a blunted sector abdominal image?

it is at the highest point in the vessel

describe the blood flow occurring in this image

• the heart is superior to the transducer

• the color detector/transducer is at the highest point in the vessel (top left of vessel in image)

• red is on the bottom of the color bar, which means that blood is flowing away from the transducer

• blood is flowing from superior to inferior

• this is normal blood flow for the femoral artery

describe the blood flow occurring in this image

• the heart is inferior to the transducer

• the color detector/transducer is at the top left edge of the color box

• red is on the top of the color bar, which means that blood is flowing toward the transducer

• blood is flowing from inferior to superior

• this is normal blood flow for the carotid artery

which is the CFV and which is the IJV and why?

• A is the IJV because blue is on top of the color bar, which means that color is flowing toward the transducer (indicator is at the right top edge of the color box)

  • blood is flowing from superior (head) to inferior (heart)

• B is the CFV because blue is on the bottom of the color bar, which means that color is flowing away from the the transducer (indicator is at the right top edge of the color box)

  • blood is flowing from inferior (legs) to superior (heart)

describe the blood flow in this image and what is unique about vascular evaluation of the brachiocephalic artery and vein? is this the brachiocephalic artery or vein?

• it is the only vascular study that is done in trans

• the color indicator is at the top right of the color box, and the heart is at the bottom left

• blue is on the bottom of the color bar, which means blood is flowing away from the transducer

• this is the brachiocephalic vein

is this the femoral artery or vein?

• this is the femoral vein

• blue is on the top of the color bar, which means that it is going toward the transducer

• blood is flowing from inferior to superior

which vessel is the femoral artery and which is the femoral vein?

• A is the femoral artery

  • red = bottom = away

• B is the femoral vein

  • blue = top = toward

is this normal flow?

• yes, this is normal antegrade flow

• red = top = toward

• blood is flowing from inferior (heart) to superior (brain)

is this normal flow?

• yes, this is normal antegrade flow

• blue = top = toward

• blood is flowing from superior (head) to inferior (heart)

using direction of flow, explain which vessel is the CCA

• blue = top = toward = blood is flowing from superior to inferior

• red = bottom = away = blood is flowing from inferior to superior

  • the red (posterior) vessel is the CCA

what directions do the labels represent?

• D: superior

• A: anterior

• B: inferior

• C: posterior

what directions do the labels represent?

• D: right

• A: anterior

• B: left

• C: posterior

the flow in this femoral artery goes from

superior to inferior

the direction of flow for this IJV in this image is

superior to inferior

the direction of flow for this carotid artery in this image is

inferior to superior

the direction of flow for this internal carotid artery in this image is

inferior to superior

the direction of this common carotid artery blood flow is

inferior to superior

the direction of flow in this aorta is

superior to inferior

the direction of flow in these vessels is

inferior to superior

what vessels are these by looking at the color flow?

veins

the direction of flow in this femoral vein is? and is it antegrade or retrograde flow?

• superior to inferior

• flow for the femoral vein is supposed to go from inferior (legs) to superior (heart)

what is the direction of flow in vessel A?

cannot determine direction of flow
