Differentiation of Renal Clear Cell Carcinoma and Renal Papillary Carcinoma Using Quantitative CT Enhancement Parameters
TL;DR: A new method was used to standardize enhancement measurement in lesions on multiphasic CT not being influenced by intrinsic factors like cardiac output, which enables accurate differentiation between renal clear cell carcinoma and renal papillary carcinoma.

Treatment of malignant biliary obstruction with polyurethane-covered Wallstents.
Klaus A. Hausegger,Siegfried Thurnher,G Bodendörfer,C L Zollikofer,M. Uggowitzer,C. Kugler,Johannes Lammer +6 more
TL;DR: This prototype of a covered stent did not provide better results than did conventional uncovered stents in patients with malignant biliary obstruction, and the covering did not effectively prevent tumor ingrowth in at least two patients.
Improvement of parenchymal and vascular enhancement using saline flush and power injection for multiple-detector-row abdominal CT.
Helmut Schoellnast,Manfred Tillich,Hannes Deutschmann,Uwe Stessel,Michael J. Deutschmann,Gottfried J. Schaffler,Renate Schoellnast,M. Uggowitzer +7 more
TL;DR: The use of a double syringe power injector with saline flush following low dose contrast material bolus significantly improves parenchymal and vascular enhancement during contrast-enhanced abdominal MDCT with low iodine doses.

Focal nodular hyperplasia and hepatocellular adenoma of the liver: differentiation with multiphasic helical CT.
Andrea J. Ruppert-Kohlmayr,M. Uggowitzer,C. Kugler,Doris Zebedin,Gottfried J. Schaffler,Georg S. Ruppert +5 more
TL;DR: The attenuation and relative enhancement in the arterial phase show significant differences that make accurate differentiation between focal nodular hyperplasia and hepatocellular adenoma possible.

Abdominal multidetector row computed tomography: reduction of cost and contrast material dose using saline flush.
Helmut Schoellnast,Manfred Tillich,Hannes Deutschmann,Michael J. Deutschmann,G. A. Fritz,Uwe Stessel,Gottfried J. Schaffler,M. Uggowitzer +7 more
TL;DR: Using a saline flush after the contrast material bolus in abdominal MDCT allows an iodine dose reduction of approximately 6 g, or 17%, without impairing mean parenchymal and vascular enhancement and a cost reduction of $7.30 per patient.
