Contrast-enhanced sonography shows hyperechoic enhancement (5 min) of
infiltrated lung (LU) in late parenchymal phase compared with splenic (S)
enhancement (5 min).
Fig. 6B71-year-old man with pneumonia. Contrast-enhanced sonography
shows short time to enhancement. In early parenchymal phase, marked tissue
enhancement is seen (20 s).
Fig. 7B72-year-old man with pneumonia. Contrast-enhanced sonography
shows short time to enhancement (2 min). In parenchymal phase, hypoechoic
tissue enhancement is seen with anechoic areas caused by necrosis (N)
(arrows).

without evidence of lung metastases by CT. B-mode sonography shows round
atelectasis (A) and pulmonary effusion (E).
Fig. 8B52-year-old woman with ovarian cancer and exudative effusion
without evidence of lung metastases by CT. Contrast-enhanced sonography shows
short time to enhancement (1 min). In parenchymal phase, isoechoic tissue
enhancement compared with splenic enhancement (S) is seen.
Fig. 9B71-year-old woman with lung cancer. Contrast-enhanced
sonography shows short time to enhancement (3 s) with treelike enhancement of
pulmonary vessels in arterial phase (arrow).
Fig. 9C71-year-old woman with lung cancer. In parenchymal phase,
homogeneous tissue enchancement (35 s) is seen with demarcation of hypoechoic
central lesion (TU).
Fig. 10B64-year-old man with malignant melanoma and lung metastases.
Contrast-enhanced sonography shows short time to enhancement (3 min). In
parenchymal phase, marked tissue enhancement is seen with demarcation of
hypoechoic paranchymal lesion (M).
Fig. 11B48-year-old man with lung cancer. Contrast-enhanced
sonography shows short time to enhancement (1 min). In parenchymal phase,
isoechoic tissue enhancement compared with spleen (S) is seen. Demarcation of
areas with anechoic enhancement suggests necrosis (N).
Fig. 12B53-year-old woman with fever and lung cancer.
Contrast-enhanced sonography shows delayed time to enhancement (1 min). In
parenchymal phase, reduced tissue enhancement is seen with demarcation of
anechoic area, suggesting lung abscess (A).

parenchymal phase, hypoechoic enhancement (4 min) of atelectasis (AT) compared
with splenic enhancement (S) is seen.
