Sequential fast 3D MRI following oral ingestion of Gd-DOTA: A new means to assess intestinal transit time.
نویسندگان
چکیده
A magnetic resonance image (MRI)-based method to determine the colonic transit time is described. It is based on the oral ingestion of a single dose of 4 ml Gd-DOTA following an overnight fast and the subsequent acquisition of fast three-dimensional (3D) gradient-echo sequences under apnea conditions. The technique was successfully evaluated in three healthy volunteers. Transit of the contrast agent through the small and large intestines was easily followed. Thus, MRI-based colonic transit time determinations are feasible.

OBJECTIVE To compare P792 (gadomelitol, a rapid clearance blood pool MR contrast agent) with gadolinium-tetraazacyclododecanetetraacetic acid (Gd-DOTA), a standard extracellular agent, for their suitability to diagnose a pulmonary embolism (PE) during a first-pass perfusion MRI and 3D contrast-enhanced (CE) MR angiography (MRA). MATERIALS AND METHODS A perfusion MRI or CE-MRA was performed in...
متن کاملManufacturing and in vivo inner ear visualization of MRI traceable liposome nanoparticles encapsulating gadolinium
BACKGROUND Treatment of inner ear diseases remains a problem because of limited passage through the blood-inner ear barriers and lack of control with the delivery of treatment agents by intravenous or oral administration. As a minimally-invasive approach, intratympanic delivery of multifunctional nanoparticles (MFNPs) carrying genes or drugs to the inner ear is a future therapy for treating inn...
متن کاملMRI detection of breast cancer micrometastases with a fibronectin-targeting contrast agent
Metastasis is the primary cause of death in breast cancer patients. Early detection of high-risk breast cancer, including micrometastasis, is critical in tailoring appropriate and effective interventional therapies. Increased fibronectin expression, a hallmark of epithelial-to-mesenchymal transition, is associated with high-risk breast cancer and metastasis. We have previously developed a penta...
متن کاملNew fluorinated Gd-AspGlyMe-DOTA complexes for F-MRI
Introduction F-MRI gets an interesting method for molecular imaging. The high MR sensitivity and very low natural abundance in living organisms makes fluorine interesting in medical diagnostic. Mostly perfluorinated contrast agents like perfluorocarbons will be used. Synthesis of fluorinated Gd-contrast agents allow to record Fimages without any background signals and additional classical H-MR ...

PURPOSE To investigate the in vivo T1 -enhancement of the lung parenchyma in free-breathing healthy mice following intratracheal administration of Gd-DOTA-based nanoparticles, to assess the enhancement kinetics of the instilled contrast medium and to identify its elimination pathways. METHODS Ultrashort Echo Time (276 μs) proton MRI of the lung was performed (N = 14) at 4.7 T after the intrat...
