Accumulation of Bile in the Gallbladder: Evaluation by means of Serial Dynamic Contrast-Enhanced Magnetic Resonance Cholangiography with Gadolinium Ethoxybenzyl Diethylenetriaminepentaacetic Acid

open access: yesGastroenterology Research and Practice, 2014
The aim of this study was to evaluate the process of biliary excretion of gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) into the biliary tract and to assess the accumulation patterns in the gallbladder using MR cholangiography ...

Dumbbell‐Structured Plasmonic‐Enhanced Optical Nanoprobes Boosting Photo‐Magnetic‐Acoustic Multimodal Imaging‐Guided Photodynamic‐Photothermal Synergistic Treatment and Immunogenic Death in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, Volume 13, Issue 39, 13 July 2026.
This study reports a novel rationally‐designed optical nanoprobe based on dumbbell‐shaped mesoporous silica‐coated gold nanorods, loaded with rare‐earth oxides, photosensitizers, and tumor‐targeted peptides, enabling plasmonic‐enhanced multimodal imaging and PTT‐PDT synergy.

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

open access: yesBMC 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

Impact of Recanalization on Liver Hypertrophy after Portal Vein Embolization and the Role of Re‐Embolization

open access: yesAnnals of Gastroenterological Surgery, Volume 10, Issue 4, Page 1309-1319, July 2026.
This retrospective study of 249 patients undergoing hepatectomy after right portal vein embolization (PVE) demonstrated that major recanalization–defined as recanalization more than one segment within the embolized liver–was associated with impaired regeneration of the future liver remnant (FLR).

Parameter Optimization for Quantitative Signal-Concentration Mapping Using Spoiled Gradient Echo MRI

open access: yesRadiology Research and Practice, 2012
Rationale and Objectives. Accurate signal to tracer concentration maps are critical to quantitative MRI. The purpose of this study was to evaluate and optimize spoiled gradient echo (SPGR) MR sequences for the use of gadolinium (Gd-DTPA) as a kinetic ...

Gadolinium-DTPA enhanced MRI in neonatal osteomyelitis of the cervical spine

open access: yesThe British Journal of Radiology, 1992
Although the radiographic features of neonatal osteomyelitis are well described, spinal localizations are very rare and occur in about 2–4%. Clinical presentation with paresis and paralysis occurs in less than 1% (Resnick & Niwayama, 1988). In the neonate negative bone scintigraphy in the presence of bony destruction is not inconsistent with ...

Utility of Gd-EOB-DTPA-Enhanced MRI in Diagnosing Small Hepatocellular Carcinoma

open access: yesCase Reports in Gastroenterology, 2009
We describe an 8-mm hepatocellular carcinoma (HCC) with hepatitis C virus-related cirrhosis in a 74-year-old woman. Ultrasound (US) revealed an 8-mm hyperechoic nodule in segment 6 of the liver.

The blood–brain barrier is intact after levodopa-induced dyskinesias in parkinsonian primates—Evidence from in vivo neuroimaging studies

open access: yesNeurobiology of Disease, 2009
It has been suggested, based on rodent studies, that levodopa (l-dopa) induced dyskinesia is associated with a disrupted blood–brain barrier (BBB). We have investigated BBB integrity with in vivo neuroimaging techniques in six 1-methyl-4-phenyl-1,2,3,6 ...
