What is OMNISCAN used for?
OMNISCAN is a gadolinium-based contrast agent for diagnostic magnetic resonance imaging (MRI) indicated for intravenous use to: Visualize lesions with abnormal vascularity in the brain, spine, and associated tissues.
What is OMNISCAN contrast dye?
OMNISCAN is a gadolinium-based contrast agent indicated for intravenous use in MRI to visualize lesions with abnormal vascularity (or those thought to cause abnormalities in the blood-brain barrier) in the brain (intracranial lesions), spine, and associated tissues [see Clinical Studies].
What drugs interact with MRI contrast?
In patients with cardiovascular disease, kidney disease, and/or diabetes, renin-angiotensin system blockers, non-steroidal anti-inflammatory drugs, diuretics, and metformin can increase the risk of CI-AKI when undergoing contrast imaging.
What is systemic fibrosis?
Nephrogenic systemic fibrosis (NSF) is a rare disease that can affect different parts of the body. It most commonly first appears as swelling or itching of the skin. It can lead to thickening or hardening of the skin and deposits in other parts of the body.
How do I give optison?
OPTISON is administered via an intravenous injection to allow the microspheres to enter the heart chamber and fill the left heart chamber. OPTISON is injected during the ultrasound examination in order to allow the doctor to assess the function of your heart. The recommended dose is 0.5 ml – 3.0 ml per patient.
What should you not do before an MRI with contrast?
Preparation for your MRI Appointment: Do not have anything to drink 1-hour before your appointment time. If you have experienced previous nausea or vomiting with Gadolinium in the past, contact your referring physician concerning an anti-emetic prescription. Take your medications as usual unless otherwise instructed.
How do I get rid of gadolinium after MRI?
Chelation is a process where doctors administer chelating agents to patients. These agents bind gadolinium and remove it from the body through the kidneys. Health providers may administer chelating agents through an IV, with a pill, as a suppository under the tongue or through a rectal suppository.
Is gadolinium used in T1 or T2?
Contrast agents containing gadolinium shorten the T1 (or longitudinal) and T2 (or transverse) relaxation time of neighbouring water protons (Fig. 1). These effects increase the signal intensity of T1-weighted images, and reduce the signal intensity of T2-weighted images (5,6).

What is NSF fibrosis?
Nephrogenic systemic fibrosis (NSF) is a rare disorder that occurs in some individuals with reduced kidney function, who have been exposed to an intravenous contrast material that contains gadolinium. A contrast material is a dye that is sometimes used during magnetic resonance imaging (MRI).
