D Ave, Madison, WI 53792-3252; Division of Radiology, University of Yamanashi, Yamanashi, Japan (U.M., K.S.); and Department of Radiology, University Hospital Hamburg-Eppendorf, Hamburg, Germany (P.B.)AbstractPurpose–To investigate the cause of imaging artifacts observed throughout gadoxetic acid nhanced arterial phase imaging from the liver. Supplies and Methods–This HIPAA-compliant study was approved by the institutional overview board. Data have been collected prospectively at two websites (web page A, United states of america; internet site B, Japan) from sufferers undergoing contrast material nhanced MR imaging with gadoxetic acid (website A, n = 154, dose = 0.05 mmol/kg; web-site B, n = 130, 0.025 mmol/kg) or gadobenate dimeglumine (only internet site A, n = 1666) from January 2014 to September 2014 at internet site A and from November 2014 to January 2015 at web page B. Detailed comparisons between the two agents were produced within the patients with dynamic liver acquisitions (n = 372) and age-, sex-, and baseline oxygen saturation (Spo2)matched pairs (n = 130) at web-site A. Acquired data incorporated self-reported dyspnea after contrast agent injection, Spo2, and breath-hold fidelity monitored with respiratory bellows. Results–Self-reported dyspnea was additional frequent with gadoxetic acid than with gadobenate dimeglumine (site A, 6.5 [10 of 154] vs 0.1 [two of 1666], P .001; web page B, 1.five [two of 130]). Inside the matched-pair comparison, gadoxetic acid, as compared with gadobenate dimeglumine, had greater breath-hold failure prices (web page A, 34.six [45 of 130] vs 11.7 [15 of 130], P .0001; internet site B, 16.2 [21 of 130]) and much more serious artifacts throughout arterial phase imaging (website A, 7.7 [10 of 130] vs 0 [none of 130], P .001; site B, two.three [three of 130]). Severe imaging artifacts in sufferers who received gadoxetic acid had been considerably associated with maleAddress correspondence to U.M. ([email protected]).

Conclusion–Severe motion-related artifacts in the arterial phase of gadoxetic acid nhanced liver MR imaging are connected with breath-hold failure but not with subjective feelings of dyspnea or even a substantial reduce in blood Spo2. Subjective feelings of dyspnea are not necessarily associated with imaging artifacts. The phenomenon, albeit at a reduced rate, was confirmed at a second.
