This phase 1b open label, dose-escalating investigation study is to evaluate the dose dependent initial efficacy of the use of MT218 injection for biomarker targeted MR molecular imaging (MRMI) of prostate cancer in patients scheduled for radical prostatectomy.
Rationale: Dotarem provides superior enhancement characteristics compared to other GBCA in fMRU Specific Aims: Compare enhancement characteristics of Dotarem to other GBCAs in the kidneys used in fMRU Primary Objectives: Review functional analysis curves and data of fMRU studies and determine enhancement characteristics in the kidneys of the three GBCAs (Dotarem, Gadovist, Magnevist)
This study aims at a direct comparison between Multihance and a validated comparator like Omniscan in a cross-over individual design in patients with brain tumors to confirm the superior overall diagnostic performance of MuliHance for this indication
Researchers are looking for a better way to help people with any known or suspected problems (except brain or spinal cord-related problems) scheduled for a "contrast-enhanced" Magnetic Resonance Imaging (MRI). MRI is used by doctors to create detailed images of the inside of the body to identify health problems. Sometimes doctors need to inject contrast agent into a patient's vein to perform a so called "contrast-enhanced" MRI (CE-MRI). Such CE-MRI examinations may support doctors to identify certain health problems or improve the evaluation. The contrast agents commonly used in MRI are gadolinium-based contrast agents (GBCAs). GBCAs contain a "rare earth" element called gadolinium (Gd). Gadoquatrane is a new contrast agent under development with a lower amount of Gd needed per CE-MRI. The main purpose of this study is to learn whether CE-MRI scans with gadoquatrane work better than MRI scans without the use of a contrast agent (GBCA). The researchers will compare the ability to detect known or suspected problems (except brain or spinal cord-related problems) with gadoquatrane-MRI scans to plain-MRI scans without the use of a contrast agent. The participants will undergo 2 MRI scans, one with gadoquatrane and one with currently used GBCA. Both contrast agents will be injected into the vein. Each participant will be in the study for between 6 and 42 days with up to 7 doctor visits. At the start or during the study, the doctors and their study team will: * take blood and urine samples * do physical examinations * check blood pressure and heart rate * review the MRI scans obtained in the study and decide on the diagnosis * ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatments.

This is an observational study, in which data associated with the wastage with the use of Gadavist single-dose vials, as compared to the wastage associated with the use of the Gadavist imaging bulk packages (IBP) used for contrast-enhanced magnetic resonance imaging (MRI) using Gadavist will be compared. MRI is a medical technique, which creates detailed images of the organs, soft tissues and structures inside the body. Combination of MRI with a "dye" that is injected into the vein (called contrast media, like Gadavist) creates what is called a contrast-enhanced MRI that enables clearer pictures of the body and helps doctors to see problems better than an MRI without contrast media. The drug Gadavist (also called gadobutrol) is a gadolinium-based contrast media for diagnostic use in MRI, which is given as an injection into the vein to improve the quality of the MRI pictures. Gadavist is already approved for several indications including imaging of brain and spinal cord, breast imaging, imaging of blood vessels, and diagnoses of heart disease. It helps doctors for example to detect: * areas with disrupted blood brain barrier (BBB), which is crucial to protect the brain from toxic components and pathogens (germs, viruses, disease-causing agents) * abnormal blood vessels in certain blood vessels * presence and size of breast cancer * heart disease The dosing of Gadavist is weight-based and currently available in single-use vials, which are associated with wastage. To reduce wastage and wastage associated costs, multi-dose vials, also called imaging bulk packages (IBP) were developed, which are already approved in the USA since January 2021. The aim of this study is to understand how much of the contrast agent Gadavist is used and how much is wasted in two different containers (single-dose vials and Imaging Bulk Packages (IBP)) in a real-world setting. To do this, researchers will review information collected regarding the amount of Gadavist used for patients undergoing contrast-enhanced MRI for any indication regarding: * vial type (single-dose or IBP) * size of single-dose or IBP * volume of administered dose (mL) * date of administration * time of administration * injection modality (manual vs power) * type of power injector, if applicable There will be no study-mandated visits or treatments. The decision to undergo a contrast-enhanced MRI with Gadavist will be made by the study participants with their doctors before data collection, and independently of this study. Data will be collected over a period of approximately 6-weeks, until the data collection of 1200 participants for each comparison group (vial type) is completed. No patient information beyond Gadavist dose will be collected in this study.
Researchers in this study want to learn how a new contrast agent for magnetic resonance imaging (MRI) called BAY1747846 moves into, through and out of the body (pharmacokinetics) after injection in participants with normal and impaired renal function. Impaired renal function is a condition where the kidneys do not work as well as they should. BAY1747846 belongs to the class gadolinium-based contrast agents (GBCAs). The way the body removes GBCAs including BAY1747846 from the blood is through the kidneys. So, when the kidneys are not working normally, it takes longer to remove BAY1747846 out of the body. The participants in this study will either have normal renal function, or will have mild or moderate impaired renal function. The participants will receive BAY1747846 one time through a needle into a vein. During the study, the participants will visit the study site about 6 times. The participants will stay at the study site for up to 9 days. Each participant will be in the study for up to 7 months. During the study, the doctors will: * check the participants' overall health * take blood and urine samples * ask the participants about what medications they are taking and what adverse events they are having An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
Researchers in this study want to find the appropriate dose of drug BAY1747846 for adults undergoing MRI for known or highly suspected brain and/or spinal cord conditions so that the image quality is similar to that of drug gadobutrol for adults undergoing MRI. MRI stands for Magnetic resonance imaging which produces body pictures created by using magnetic energy rather than x-ray energy. Both BAY1747846 and gadobutrol are medicinal products known as gadolinium-based contrast agents (GBCA) which are used in MRI examinations to provide contrast enhancement and improve imaging performance. Gadobutrol (brand name: Gadavist, Gadovist) has been approved worldwide for the diagnosis of various disorders in adult and pediatric patients. BAY1747846 is a new GBCA under development with the goal to provide similar imaging performances in MRI. Participants in this study will receive both BAY1747846 and gadobutrol with a period of 3 - 14 days in between. A MRI examination will be performed after each injection. Participant will stay in this study for 2 - 4 weeks depending on the scheduling of the visits.
This is an open-label, multi-center study involving babies 0-2 months of age who have liver problems (pathology) and need to have their liver and possibly, the bile ducts imaged using magnetic resonance imaging and injection of a contrast agent (dye). This agent is called Eovist. It has been marketed since 2004 and used in many countries all over the world. The baby will have blood tests before and after the imaging is done to make sure that there are no unexpected findings before and after the imaging. Also 3 blood samples up to 8 hours after the injection will be obtained in order to measure how much of the dye is in the blood. The baby will have an intravenous line which can be used for the blood samples and will not need to be stick for the blood samples. Several radiologists will evaluate the images. The family doctor will be contacted to find out what was the diagnosis and treatment after the results of the MRI were known. Six months after the study, the parent(s)/legal guardian(s) will be contacted to make sure the that baby did not have any problems, especially with the skin, joints and eyes.
This is a pilot study of patients with clinical symptoms of Ménière's disease using injection of diluted magnetic resonance imaging (MRI) contrast agent into the ear to evaluate inner ear structures. The goal is to reproduce imaging findings described by non-United States (US) institutions, improve on image quality with decreased scan time and evaluate the dynamics of the contrast movement into the inner ear structures.
This will be an international, multi-center, post-marketing surveillance study in patients with moderate renal insufficiency who are administered gadodiamide, Omniscan, during a MRI. Omniscan will be administered intravenously at the medical discretion of the prescribing physician.
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
The purpose of this study is to compare contrast agents, Dotarem or MultiHance. The study will test to see how much of these two contrast agents are deposited in the bones or tissues of pediatric patients. The patients receiving contrast will then be compared against pediatric patients who have not received any contrast prior to cardiac surgeries.
This study is a postmarketing requirement jointly carried out by four NDA holders (Bayer AG, Bracco, GE Healthcare and Guerbet) and the CRO IQVIA. The study aims to create detailed images of the organs and tissue of the human body during x-ray, CT-scan or MRI investigations, doctors are using contrast media (a kind of dye) which can be given to patients by injection into a blood vessel or by mouth. In this study researchers want to find out whether so called gadolinium-based contrast agents (GBCAs) have an effect on body movement and mental skills when given to participants multiple times within 5 years. The study plans to enroll about 2076 participants suffering from a condition for which they are likely to have at least annually a MRI or another imaging examinations. Only adults up to 65 years will be considered to join this study. During the study duration of 5 years participants will receive annually a MRI or other imaging tests (such as CT-scan, x-ray) and will visit the study doctor at least 7 times for physical examinations, laboratory investigations and tests on body movement and mental skills.
This study is for individuals with decreased kidney function whose doctor has ordered Magnetic Resonance Imaging (MRI). Because kidney function is decreased, these patients usually do not receive the intravenous contrast material that can improve the accuracy of the MRI findings. The purpose of this study is to evaluate the safety and benefit of using a contrast material called Gadoterate in patients with decreased kidney function.
The goal of this clinical research study is to learn if ferumoxytol, when given at the time of a magnetic resonance imaging (MRI), can help researchers learn more about the spread of certain kinds of cancers. Ferumoxytol is designed to deliver iron to treat iron-deficiency anemia (low red blood cell counts) in patients with chronic kidney disease. In this study, it will be used as an MRI contrast. Contrasts are used by doctors in order to see MRI images more clearly.
* The investigators are conducting a magnetic resonance imaging (MRI) study comparing two MRI contrast agents in people with clinically isolated syndrome and relapsing remitting multiple sclerosis (MS). MS is a disease that affects the white matter and gray matter in the brain. MRI is used as a gold standard to visualize the degenerative changes in the brain and spine. The neurologist will usually order an MRI to confirm the diagnosis of MS using conventional imaging methods. These images reveal two main pieces of information regarding (a) the location of the lesions and (b) the status of the lesions. While the location of the lesions directly correlates with the clinical symptoms, the information about the status of the lesions informs the neurologist whether the lesion is new (active) or old (chronic). * This ability to differentiate new and old lesions requires the use of a contrast agent. Currently, used agents reveal some lesions but it is unclear if they reveal the full extent of the disease. In new lesions, there may be a leakiness in the blood vessels and if the contrast agent leaks out then the investigators can see this. In healthy controls, the blood brain barrier is usually intact and this leak does not happen. One open question is: "can the extravasation of the contrast agent to the brain precede the major tissue damage that we see in the structural MRI?" * Recently, a new FDA approved contrast agent (Gadavist) has been released and has enhanced characteristics in terms of affecting the MR signal resulting in a better contrast in the image and therefore, better diagnosis of the status of the disease. Given its high relaxivity, a small amount of Gadavist may show a better signal enhancement affected tissue for multiple sclerosis patients. The investigators hypothesize that Gadavist will reveal more tissue damage (lesions) than Magnevist and, therefore, may present a better tool for early diagnosis of brain damage. * The investigators' goal in this research project is to see if the newer contrast agent is able to detect changes and differentiate healthy from affected tissue in the white matter and gray matter earlier than current contrast agents so that detection can be possible before major damage occurs to the tissue. Each person will be scanned initially with one agent and then between 8 and 30 days later with the other agent. The MR data processing results will be compared to check the efficacy of each contrast agent.
The purpose of this study is to determine pharmacokinetics, safety and efficacy of Magnevist in children 2 months to \< 2 years of age
The goal of this clinical research study is to learn if magnetic resonance imaging with magnetic resonance spectroscopy ("MRI/MRS" scanning) can measure any extra growth in the tumor that does not show up on regular MRI images. This study procedure will be performed on patients with recurrent glioblastoma who are either being treated with chemotherapy that blocks blood vessel growth, or will soon begin this type of chemotherapy.
