CH 16 CEUS Flashcards
1
Q
When is initial and peak enhancement for CEUS of the liver?
A
starts about 10s
peak 20-30s
then uniform perfusion
2
Q
benign or malignant lesion?
A
malignant
Benign liver lesions typically enhance to a similar
degree as the surrounding liver parenchyma at peak enhancement, whereas neoplastic lesions lack the portal venous blood supply and remain hypoperfused at peak enhancement (Figure 16.4).
3
Q
How do malignant liver lesions behave on CEUS?
A
they stay hypoperfused, because they don’t have portal supply (which is where the contrast comes from)
4
Q
Liver CEUS has what level of sensitivity for differentiating benign / malignant lesions ?
A
97%,
