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."

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."

This approach can be used to optimize routine clinical MRI protocols and balance scan time with contrast enhancement. This may translate to more precise lesion detection, potentially leading to earlier and more accurate diagnosis or treatment monitoring in clinical practice."

FROP-1 peptide-conjugated ultrasmall superparamagnetic nanoparticles as a targeted T1-weighted MR contrast agent for breast cancer: in vitro study. (PubMed, BMC Biomed Eng) - "It was found that the contrast intensity of the Fe3O4@FROP-1 nanoprobe increases as Fe concentration increases. Cellular uptake of the Fe3O4 and Fe3O4@FROP-1 NPs was quantified using ICP-MS. The synthesized NPs had better imaging performance than Dotarem (gadoterate meglumine). The findings showed that Fe3O4@FROP-1 NPs have potential utility as a specific and targeted T1-weighted contrast agent in breast cancer MR imaging."

Exploring Gadolinium Deposition in Maternal and Offspring Mice: Impacts of Gestational and Lactational Exposure. (PubMed, Toxicol Lett) - "To investigate the gadolinium deposition induced by repeated administration of gadolinium-based contrast agents (GBCAs) in multi-organ/tissue of mother and pup mice during pregnancy and lactation, two hundred and seventy ICR mice were divided into three groups (non-pregnant, pregnant, and lactating; n=90/group) and received gadodiamide, gadoterate meglumine, or saline intravenously (2.5mmol Gd/kg once every two days for a total of 10 doses) throughout the entire gestation or lactation period...Our results showed that (i)exposure to GBCAs during pregnancy resulted in gadolinium deposition in fetal organs more significantly with gadodiamide, with the greatest deposition observed in the kidneys and the least in the brain, interestingly, the fetal body was found with no detectable gadolinium deposits one month after birth, that (ii) exposure to GBCAs during lactation did not result in detectable gadolinium deposition in the organs/tissues of the unweaned pups, and that..."

Concentration-dependent bidirectional modification of evoked synaptic transmission by gadolinium and adverse effects of gadolinium-based contrast agent. (PubMed, J Neurosci) - "Gadoterate meglumine (Magnescope, 100 μM), a macrocyclic GBCA, did not affect synaptic transmission. However, gadopentetate dimeglumine (Magnevist, 100 μM), a liner GBCA, enhanced synaptic transmission, suggesting that gadopentetate dimeglumine does not fully chelate gadolinium, which can have a negative effect on brain function."
