Fig. 1A. 47-year-old man with solitary hepatocellular carcinoma
related to viral hepatitis type Cinduced cirrhosis. Two of three
observers missed lesion on image set 4. Transverse unenhanced T1-weighted
gradient-echo MR image (TR/TE, 140/4.1) shows no focal lesion.

Fig. 1B. 47-year-old man with solitary hepatocellular carcinoma
related to viral hepatitis type Cinduced cirrhosis. Two of three
observers missed lesion on image set 4. Transverse unenhanced T2-weighted fast
spin-echo MR image (3300/138) (B) and transverse ferumoxides-enhanced
T2-weighted fast spin-echo MR image (3300/138) (C) show no focal
lesion. Note severe motion-related artifacts (arrows).

Fig. 1D. 47-year-old man with solitary hepatocellular carcinoma
related to viral hepatitis type Cinduced cirrhosis. Two of three
observers missed lesion on image set 4. Transverse ferumoxides-enhanced
T1-weighted gradient-echo MR image (140/4.1) shows lesion with decreased
signal loss. Lesion (arrow) is 1.5 cm in diameter in segment VII.

Fig. 1E. 47-year-old man with solitary hepatocellular carcinoma
related to viral hepatitis type Cinduced cirrhosis. Two of three
observers missed lesion on image set 4. Transverse ferumoxides-enhanced
T2*-weighted gradient-echo MR image (140/10) shows best contrast
between lesion and surrounding liver (arrow). Note fibrotic changes
of decreased signal loss (arrowheads) caused by severe cirrhosis.

Fig. 1F. 47-year-old man with solitary hepatocellular carcinoma
related to viral hepatitis type Cinduced cirrhosis. Two of three
observers missed lesion on image set 4. Photomicrograph of histologic specimen
from nodule shows moderately differentiated hepatocellular carcinoma with
tubercular sinusoidal structure (H and E, x50). Insert (lower right)
shows foci of clear cell differentiation (H and E, x200).

Fig. 2A. 40-year-old man with fibrotic lesion in alcohol-induced
cirrhosis. Two of three observers recognized lesion as possibly malignant on
image set 4. Transverse unenhanced T1-weighted gradient-echo MR image (TR/TE,
140/4.1) (A), transverse unenhanced T2-weighted fast spin-echo MR image
(3300/138) (B), and transverse ferumoxides-enhanced T2-weighted fast
spin-echo MR image (3300/138) (C) show no focal lesion.

image (140/4.1) (D) and transverse ferumoxides-enhanced

cirrhosis. Two of three observers recognized lesion as possibly malignant on
image set 4. Photomicrograph of histologic specimen from lesion shows
cirrhotic liver with dense fibrous stroma, proliferation of bile ducts, and
mild chronic inflammation. (H and E, x50)
