Is Eovist the same as gadolinium?
EOVIST® Injection is a gadolinium-based contrast agent indicated for intravenous use in T1 weighted magnetic resonance imaging (MRI) of the liver to detect and characterize lesions in adults with known or suspected focal liver disease.
Can you use Eovist for brain MRI?
The 2 agents not approved for CE-MR imaging of the CNS (gadofosveset trisodium, Ablavar, Lantheus Medical Imaging, North Billerica, Massachusetts; and gadoxetic acid, Bayer HealthCare Pharmaceuticals [Eovist or Primovist]) have distinct properties that render them unsuitable for this indication; Ablavar8 is an …
When do you use Eovist?
1. The approved indication for Eovist is for detecting and diagnosing liver lesions. 2. Dynamic multiphasic imaging is possible with Eovist, but is less optimal unless it is given as double the recommended dose.
What enhances with Eovist?
Eovist Injection or gadolinium EOB-DTPA is a water-soluble ethoxybenzyl derivative of gadolinium DTPA. The presence of the ethoxybenzyl group causes this compound to be selectively taken up by the hepatocytes. This uptake leads to enhancement of liver parenchyma on T1-weighted images.
What is the difference between gadavist and Eovist?
Gadavist (gadobutrol) and Eovist (gadoxetate disodium) are available as sterile solutions for injection and are administered intravenously. Structurally, Gadavist is a macrocyclic gadolinium-based contrast agent (GBCA), and Eovist is a linear GBCA.
Is Eovist safe for kidneys?
The administration of contrast agents that contain gadolinium such as Primovist/Eovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment.
Is gadavist the same as Eovist?
Structurally, Gadavist is a macrocyclic gadolinium-based contrast agent (GBCA), and Eovist is a linear GBCA.
How long does Eovist stay in body?
Gadoxetate can stay in your body for months or years after you receive this medicine. It is not known whether this could cause any health problems in people whose kidneys work properly. Tell your doctor if you have had repeated scans with a contrast agent, and provide the date of your last scan.
Is primovist a gadolinium?
Gadoxetate disodium (also known by the tradenames PrimovistTM and EovistTM) is a hepatospecific paramagnetic gadolinium-based contrast agent, used exclusively in MRI liver imaging. Its chief use is in hepatic lesion characterisation, i.e. assessing focal liver lesions identified on other imaging studies.
Are there different types of gadolinium?
Gadolinium based contrast agent in its original form is not toxic. This because the contrast agents contain “chelates” which are molecules that bind to the elemental gadolinium and allows it to be removed from your body through your kidneys. There are 2 different types of contrast agents, linear and macrocyclic agents.
Does Eovist contain gadolinium?
EOVIST® Injection is a gadolinium-based contrast agent indicated for intravenous use in T1 weighted magnetic resonance imaging (MRI) of the liver to detect and characterize lesions in adults with known or suspected focal liver disease. The recommended dose of EOVIST is 0.1 mL/kg body weight (0.025 mmol/kg body weight).
What is focal nodular hyperplasia (FNH)?
Liver MRI with Eovist is reserved primarily for diagnostically characterizing a liver lesion as focal nodular hyperplasia (FNH). FNH is the second most common benign lesion in the liver (after hemangiomas) that is thought to arise as a response to a congenital arteriovenous malformation
What is the difference between adenoma and FNH on delayed imaging?
Distinct imaging characteristics of HA versus FNH on delayed gadoxetic acid-enhanced MRI, with adenomas being hypointense and FNH being iso- or hyperintense on delayed imaging may improve specificity for characterization, and aid in the differentiation of these two lesions.
Is dynamic multiphasic imaging possible with Eovist?
Dynamic multiphasic imaging is possible with Eovist, but is less optimal unless it is given as double the recommended dose. 3. The extracellular phase, useful for depicting edema and fibrosis, is not obtained following Eovist administration.

What are the stir Tju indications for an Eovist?
1. Shorter, smaller bolus 2. 20 minute delayed image 3. Timing is even more important 4. MRCP < 5 min after injection 5. STIR post contrast Pre Arterial Venous 5-min 20-min STIR TJU Indications for Eovist 1. FNH (focal nodular hyperplasia) or liver adenoma characterization. 2. Cirrhosis: HCC surveillance
