Uses of an MRI With Contrast Some uses for MRI with contrast are: 1. Assessing MS Contrast MRIs are a great way to track the progression of multiple sclerosis. MRI scans have transformed how radiologists diagnose MS, and are now the primary method doctors use to diagnose the condition, to ...
MRI. This brightness is typically proportional to the concentration of the GBCA. Tumors acquire increased vascularity due to angiogenesis, creating an environment conducive for a higher concentration of GBCA. This results in an enhanced appearance of tumors, reflected by increased signal intensity on ...
MRI is an advanced medical imaging technique used to produce high quality images of human body and different parts. It gives detail information to analyse the diseases. Medical image processing plays important role to give information in more extent for such advance images. Original MRI images are...
We herein report a novel dual-modal MRI contrast agent, TPE-2Gd, for both magnetic and fluorescence imaging. TPE-2Gd consists of a hydrophobic tetraphenylethene (TPE) fluorophore and two hydrophilic gadolinium (Gd) diethylenetriaminepentaacetic acid moieties. As an amphiphilic molecule, TPE-2Gd agg...
METHOD AND MATERIALS 21 patients (mean age 59.5 years, range 35 to 78 years, 11 female, 10 male) with suspected abdominal metastases from various primaries (lung cancer, breast cancer, melanoma) were referred for a clinical cePET/CT. An additionally PET/MRI was performed within a PET/CT-...
Objective: The objective was to retrospectively study computed tomography (CT) and magnetic resonance imaging (MRI) findings of adenosquamous carcinoma of the pancreas (PASC). Materials and Methods: Twelve patients (six women and six men; mean age, 61.3 years; range, 47-78 years) who presented...
Shown at the bottom left is a macromolecular MnII complex (D. Felder-Flesch, M. Kueny-Stotz, and A. Garofalo), which is an example of manganese-enhanced MRI contrast agents. At the bottom right, the optimization of the CEST effect for a FeII complex at close to physiological pH (J. ...

Mn-based MRI contrast agents were first used as an oral formulation containing liposome-encapsulated MnCl2 salt (LumenHance®), indicated for gastrointestinal images. Nevertheless, it was shown that too high doses of free manganese ions could induce a neurodegenerative disorder called manganism, a...
Contrast media, also called contrast agents, are used to enhance the blood and perfusion in tissues. This includes iodine based contrast for on computed tomography (CT), gadolinium based agents for MRI and lipid bubble contrast agents used in ultrasound.
