The authors evaluated a flow-independent magnetic resonance (MR) imaging technique in extremity veins with slow flow that relies on the prolonged T2 of blood to create angiographic contrast. A commercially available heavily T2-weighted fast-spin-echo sequence was optimized for MR venography in volunteer and phantom studies. Good depiction of venous anatomy was routinely obtained with the optimized method. Fast-spin-echo MR venography allowed evaluation of slow-flow systems such as the calf and forearm veins.

The purpose of this study was to evaluate the CT findings of rupture of hepatocellular carcinoma (HCC) in the caudate lobe of the liver. The CT scans of five cases of rupture of HCC in the caudate lobe of the liver were retrospectively reviewed and correlated with clinical records. All cases showed exophytic tumors in the caudate lobe of the liver and high-attenuation hematomas in the lesser sac on CT. A lesser sac hematoma may be a sentinel clot sign of rupture of HCC in the caudate lobe.
