To evaluate the value of the gadobenate dimeglumine-enhanced hepatobiliary-phase magnetic resonance (MR) imaging for the differentiation of scirrhous hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) with or without HCC. ⋯ Although both scirrhous HCC and CC with or without HCC show similar imaging findings on unenhanced and gadobenate dimeglumine-enhanced dynamic MR images, gadobenate dimeglumine-enhanced hepatobiliary-phase MR images may be helpful to differentiate scirrhous HCC from CC with or without HCC.

Pelvic CT angiography in blunt trauma: imaging findings and protocol considerations. [corrected].
The evolution of multi-row detector computed tomography (MDCT) technology has resulted in evolving applications of CT angiography (CTA) in the trauma setting. In patients with significant blunt pelvic injuries, the immediate diagnosis and characterization of vascular injuries are of significant import given their morbidity and mortality in this patient population. ⋯ This review will discuss the use of pelvic CTA in blunt pelvic trauma and its utility in detecting and characterizing vascular injury, including the differentiation of arterial from venous hemorrhage. Protocol considerations in pelvic CTA using 64MDCT technology will be detailed as well as the integration of pelvic CTA into torso CT trauma protocols.
