Randomized Controlled Trial Comparative StudyProspective randomized trial of iohexol 350 versus meglumine sodium diatrizoate as an oral contrast agent for abdominopelvic computed tomography.
To compare the efficacy and patient tolerance of iohexol and meglumine sodium diatrizoate as oral contrast agents for computed tomography (CT). ⋯ Iohexol 350 is a satisfactory oral contrast agent for abdominopelvic CT. It opacifies the gastrointestinal tract as well as meglumine sodium diatrizoate does, and patients prefer the taste of iohexol to that of diatrizoate.

Gadolinium ethoxybenzyl diethylenetriamine pentaacetic Acid-enhanced magnetic resonance imaging findings of borderline lesions at high risk for progression to hypervascular classic hepatocellular carcinoma.
The objectives of the study were to assess the imaging features of hypovascular borderline lesions containing hypervascular foci on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) and to evaluate the ability of Gd-EOB-DTPA-enhanced MRI to diagnose high-risk borderline lesions possibly consistent with early hepatocellular carcinoma (HCC). ⋯ Although many high-risk borderline HCC lesions are hypointense on hepatobiliary-phase Gd-EOB-DTPA-enhanced MRI, some high-risk borderline lesions are isointense and transform at the same rate into hypervascular HCC.
