Cyclen Tetra‐Amide Ligands as a Privileged Class of Ligands for Studying Second‐Sphere Coordination Environments

Chemistry – A European Journal, EarlyView.
Cyclen tetra‐amide derivatives provide a privileged ligand platform for controlling second‐coordination sphere structure. Hydrogen‐bond networks in the second‐coordination sphere are leveraged to stabilize a EuII‐containing cyclen tetra‐amide derivative in physiologically relevant conditions by limiting the access of O2, establishing a design‐principle

Preclinical evaluation of Gd-DTPA and gadomelitol as contrast agents in DCE-MRI of cervical carcinoma interstitial fluid pressure

BMC Cancer, 2012
Background High interstitial fluid pressure (IFP) in the primary tumor is associated with poor disease-free survival in locally advanced cervical carcinoma. A noninvasive assay is needed to identify cervical cancer patients with highly elevated tumor IFP

Gd-EOB-DTPA MRI scans showing changes in the irradiated HCC and the background liver after PBT.

, 2016
On the follow-up Gd-EOB-DTPA MRI scan, FLR did not appear 1 month later in this case. The contours of the FLR were made manually on MR images at 3 or 6 months after PBT.

Nivolumab-DTPA-Based PD-1 Imaging Reveals Structural and Pathological Changes in Colorectal Carcinoma

Frontiers in Bioengineering and Biotechnology, 2022
Programmed cell death protein 1 (PD-1) expression is considered a prognostic marker of tumor response to the immuno-blocking therapy. In this study, nivolumab was conjugated with diethylenetriamine pentaacetate (DTPA) via condensation reaction between ...

Effect of Visualized Respiratory Training on Patient Cooperation and Image Quality in Gadoxetic Acid Disodium‐Enhanced Liver MRI: A Randomized Controlled Trial

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Respiratory motion artifacts impair diagnostic accuracy in gadoxetic acid disodium (Gd‐EOB‐DTPA)‐enhanced liver MRI. Conventional verbal pre‐scan breathing training often yields inconsistent patient cooperation and image quality, creating an urgent clinical need for optimized training methods.

Impact of pre‐examination video education in Gd‐EOB‐DTPA‐enhanced liver MRI: A comparative study

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 34-41, March 2025.
This study evaluates the effects of pre‐examination video education on patient anxiety, satisfaction and image quality in Gd‐EOB‐DTPA‐enhanced liver MRI. We found that video education significantly reduced anxiety, increased patient satisfaction and improved image quality compared to standard pre‐MRI guidance, highlighting the potential of video ...
