TL;DR: These liver CEUS guidelines and recommendations are intended to create standard protocols for the use and administration of UCA in liver applications on an international basis and improve the management of patients worldwide.
Journal ArticleDOI
Single-phase dual-energy CT allows for characterization of renal masses as benign or malignant.
Anno Graser,Christoph R. Becker,Michael Staehler,Dirk A. Clevert,Michael Macari,Niko Arndt,Konstantin Nikolaou,Wieland H. Sommer,Christian G. Stief,Maximilian F. Reiser,Thorsten R. C. Johnson +10 more
TL;DR: DECT allows for fast and accurate characterization of renal masses in a single-phase acquisition and omission of a nonenhanced acquisition can reduce radiation exposure by almost 50%.
Journal ArticleDOI
High-Spatial-Resolution Multistation MR Angiography with Parallel Imaging and Blood Pool Contrast Agent: Initial Experience
Konstantin Nikolaou,Harald Kramer,C. Grosse,Dirk A. Clevert,Olaf Dietrich,Mike Hartmann,Paul Chamberlin,Stefan Assmann,Maximilian F. Reiser,Stefan O. Schoenberg +9 more
TL;DR: Vessel conspicuity on the first-pass MR angiograms obtained in both volunteers and patients was rated as excellent for 93% of vessels, and vessel conspicuity at steady-state imaging was ratedAs excellent or good for 89% of Vessel conspicuity.
Journal ArticleDOI
Image Quality of Virtual Noncontrast Images Derived from Dual-energy CT Angiography after Endovascular Aneurysm Repair
Wieland H. Sommer,Anno Graser,Christoph R. Becker,Dirk A. Clevert,Maximilian F. Reiser,Konstantin Nikolaou,Thorsten R. C. Johnson +6 more
TL;DR: Dual-energy CT makes a reliable detection of endoleaks feasible in a single acquisition and provides a potential dose reduction for patients who have to undergo lifelong follow-up examinations after endovascular aneurysm repair.
Journal ArticleDOI
Time-resolved CT angiography for the detection and classification of endoleaks.
