Comparison of transient severe motion in gadoxetate disodium and gadopentetate dimeglumine-enhanced MRI: effect of modified breath-holding method

Abstract

• The modified breath-holding method significantly reduced the incidence of TSM. • Gadoxetate disodium and gadopentetate dimeglumine showed comparable motion scores. • TSM incidence was comparable between gadoxetate disodium- and gadopentetate dimeglumine-enhanced MRI.

Respiratory motion artefacts in Gd-EOB-DTPA (Primovist/Eovist) and Gd-DOTA (Dotarem)-enhanced dynamic phase liver MRI after intensified and standard pre-scan patient preparation: A bi-institutional analysis

“…The TSM frequency discovered in our study matched the TSM frequency described previously in the literature [1][2][3][4][5][6][7][8] which corroborates the hypothesis that Gd-EOB-DTPA acts as a chemo-toxic trigger evoking TSM that cannot be willingly mitigated by education and training. Our results differ from the results of Gutzeit et al [18] and Song et al [19]. The authors reduced the incidence of TSM from 13% to 0% (4/30 vs. 0/30 patients) [18] and from 14% to 3.8% (14/100 vs. 3/80 patients) [19] by employing a modified breath-hold command with several breathing cycles prior to imaging.…”

“…Kim et al [15] as well as Polanec et al [16] found a 50% dilution of Gd-EOB-DTPA at an injection rate of 2mL/s [15] or 1mL/s [16] while Davenport et al [17] found a fixed dose of 10mL instead of 20mL to reduce Gd-EOB-DTPA-related TSM significantly. Another alternative strategy recently described was a modified breathing command that has been advocated to reduce Gd-EOB-DTPA-related TSM [18,19]. The rationale behind this modification was that accustoming patients to the pace and nature of breath-holding would be beneficial to reduce RM in general and consequently also TSM.…”

Optimized Breath-Hold Compressed-Sensing 3D MR Cholangiopancreatography at 3T: Image Quality Analysis and Clinical Feasibility Assessment

“…Furthermore, since BH-CS-MRCP is a 'breath-hold' examination, the image quality is largely dependent on the patient's compliance as well as the capability to breath-hold. Our MR radiographers are well trained in improving patient compliance, through the provision of good instructions in preparation for breath-holding image acquisition, as previously described [21,22].…”

Reduction of respiratory motion artifacts in gadoxetate-enhanced MR with a deep learning–based filter using convolutional neural network

“…In order to solve this problem, several strategies are conceivable. One potential solution can be patient-based: through informing patients concerning the problem of acute transient dyspnea or performing breath-hold practice before the scan, the rate of artifacts could be decreased [8]. Likewise, dilution of the contrast agent is able to reduce the incidence of artifacts [9,10].…”
