Clinical application of gadoterate meglumine in abbreviated dynamic contrast-enhanced magnetic resonance imaging of the breast with ultrafast imaging: a single-center retrospective study. (PubMed, Quant Imaging Med Surg) - "Ktrans had the highest diagnostic sensitivity [98.3% (95% CI: 91.1-100%), P<0.05]. Based on quantitative pharmacokinetic analysis of ultrafast DCE-MRI, the study demonstrated the viability of utilizing Dotarem as an intravenous gadolinium-based contrast agent for DCE-MRI of the breast with preserved clinical success for breast cancer detection."

Leptomeningeal vascularity in Gadopiclenol Enhanced Pediatric Brain MRI. (PubMed, AJNR Am J Neuroradiol) - "Gadopiclenol increases background extra-axial enhancement on T1-weighted post-contrast sequences in pediatric brain MRI, likely reflecting its higher relaxivity. Radiologists should be aware of this effect to avoid misinterpretation as leptomeningeal pathology. Post-contrast FLAIR remains unaffected and continues to serve as a reliable sequence for detecting true meningeal disease."

Interaction study between gadolinium-based contrast agents and lysozyme using frontal analysis continuous capillary electrophoresis. (PubMed, Anal Chim Acta) - "FACCE is a well-adapted method to investigate GBCA-protein interaction. It requires low sample volumes and allows determining the stoichiometry, binding constant, and cooperativity of the interaction. This work emphasizes the cooperative nature of the GBCA-lysozyme interactions and indicates that the Hill model is suitable for analysing the interactions within the tested concentration range of GBCAs."

Prepubertal Exposure to Gadolinium-Based Contrast Agents Impairs Sperm Quality and Elevates Oxidative Stress in Adult Rats. (PubMed, Toxicology) - "Gadoteric Acid (Dotarem®) is approved for use in children of all ages, including neonates...Furthermore, increased oxidative stress markers and lipid peroxidation were observed in sperm and testicular tissue. A single prepubertal exposure to Gd, before the establishment of testicular and epididymal barriers, may lead to long-term alterations in sperm quantitative and qualitative parameters and induce oxidative stress in sperm and male reproductive tissues in adulthood."

The value of magnetic resonance imaging in the diagnosis of extraspinal osteoarticular brucellosis. (PubMed, Medicine (Baltimore)) - "Thirty-nine patients diagnosed with brucellosis with corresponding joint pain admitted to our hospital from December 2020 to November 2021 were retrospectively analyzed as study subjects, and all of them underwent MRI, diffusion-weighted imaging, and gadoterate meglumine to observe the MRI imaging features of extraspinal osteoarthritic brucellosis and the affected joints...For abscess formation, by analyzing the joint cavity of the patient, the liquid signal shadow of T2 could be seen, and the lesion area showed noticeable uneven sheet enhancement in the enhanced scan. Extraspinal osteoarthritic brucellosis has specific characteristics in MRI, and MRI has significant clinical value in the diagnosis, differentiation, and evaluation of the therapeutic efficacy of this disease."

Heavy metal complexes can induce structural changes and mineral redistribution in fruits: MRI and X-ray evidence (ACS-Fall 2025) - "Excess biometal extraction by these contrast agents generates weakly paramagnetic species evident from T1-type of MRI signal enhancement (T1 shortening) for Dotarem or localized T2 shortening (signal decrease) in susceptibility weighted imaging if higher Gd3+ loading is present as in Gadavist. This work indicates a new mechnistic pathway via transmetallation for seemingly safe MRI contrast agents and might raise health and environmental concerns."

Testicular varicocele embolization using CO2, gadolinium and lipiodol as contrast agents in a patient with an iodinated contrast allergy. (PubMed, Radiol Case Rep) - "After coil deployment the gadolinium-based contrast agent Dotarem, was injected and venography used to confirm occlusion of the left testicular vein...Due to their different properties, a combination of alternative contrast agents can be more effective than a single agent. We provide a pictorial review of the case and an educational summary on the indications and practical uses of various alternative contrast agents in IR procedures in a patient with a water-soluble iodinated contrast allergy."

Renal perfusion assessment by magnetic resonance imaging in patients with diabetic cardiac autonomic neuropathy (ERA 2025) - "The contrast agent Dotarem (Gd-DOTA) was injected intravenously to enhance the visualisation of the kidneys, providing high-resolution images and quantifiable data on renal blood flow... This study investigated the impact of CAN on renal perfusion in individuals with type 1 and type 2 diabetes using DCE-MRI. The findings showed no significant differences in renal perfusion between 'no CAN' and 'CAN' group, challenging previous assumptions of its impact on renal perfusion due to sympathetic over activity. These outcomes highlight the need for future longitudinal studies with larger sample sizes."
