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

open access: yesJournal of Magnetic Resonance Imaging, Volume 64, Issue 5, Page 1384-1395, November 2026.
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.

Brain Clearance of Contrast Agent in Intravenous DCE‐MRI Is Measurable and Cannot Be Explained by Clearance Across the BBB Alone

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2309-2320, November 2026.
ABSTRACT Purpose To determine the feasibility of measuring brain clearance of gadolinium contrast agent using standard intravenous DCE‐MRI acquisitions and evaluate the contribution of blood–brain barrier (BBB) and non‐BBB clearance routes. Methods Uptake and extended Tofts models were fit to DCE‐MRI data from people with Parkinson's disease, post ...

Using Manganese‐Enhanced DCE‐MRI to Assess Blood‐Cerebrospinal Fluid Barrier Transport

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2083-2091, November 2026.
ABSTRACT PurposeWe developed a dynamic, heavily T2‐weighted (hT2w) FLAIR protocol to resolve acute Mn2+ transport kinetics, as a proxy for Ca2+, across the choroid plexus (ChP)—cerebrospinal fluid (CSF) interface, in vivo. By quantifying intercompartmental Mn2+ dynamics, and comparing these with Gd‐DOTA, we sought to characterize blood‐CSF‐barrier ...

Comparative biodistribution of potential anti-glioblastoma conjugates [111In]DTPA-hEGF and [111In]Bz-DTPA-hEGF in normal mice

open access: yes, 2004
EGF-receptors (EGFR) are overexpressed in gliomas, as well as in tumors of breast, lung, and urinary bladder. For this reason, EGFR may be an attractive target for both visualization and therapy of malignant tumors using radioactive nuclides.

Exploring the Mechanism of Postpartum Cognitive Dysfunction in a Preeclampsia Rat Model via Multimodal Imaging

open access: yesThe FASEB Journal, Volume 40, Issue 19, 15 October 2026.
This schematic illustrates an L‐NAME‐induced preeclampsia (PE) rat model generated via L‐NAME administration to pregnant dams, wherein Morris water maze assessments confirmed progressive postpartum cognitive dysfunction that emerged at 10 days post‐partum and deteriorated further at 1 and 3 months post‐partum. Multimodal magnetic resonance imaging (MRI)

Biokinetic Modelling of DTPA Decorporation Therapy: the CONRAD Approach

open access: yes, 2009
Administration of diethylene triamine pentaacetic acid (DTPA) can enhance the urinary excretion rate of plutonium (Pu) for several days, but most of this Pu decorporation occurs on the first day after treatment.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, Volume 20, Issue 10, Page 2424-2448, October 2026.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Advances in Peptide‐Targeted Fluorescent Probes for the Diagnosis and Therapy of Brain Disorders

open access: yesChemistryEurope, Volume 4, Issue 10, October 2026.
This review summarizes peptide‐based fluorescent probes for major brain diseases, such as Alzheimer's and Parkinson's. It highlights their precise biomarker targeting and high sensitivity for imaging pathological processes in vivo. These probes also show great potential for enabling theranostic applications, thereby offering real‐time monitoring and ...

Comparison of Gadolinium-dtpa and Polylysine-gadolinium-dtpa - Enhanced Magnetic-resonance-imaging of Hepatocarcinoma in the Rat

open access: yes, 1995
RATIONALE AND OBJECTIVES. TO compare the magnetic resonance (MR) imaging characteristics of gadolinium-DTPA (Gd-DTPA), a low-molecular-weight contrast agent, and polylysine-Gd-DTPA, a macromolecular contrast agent, in two types of hepatocarcinomas (HCC ...
