Gadodiamide
Gadodiamide is a paramagnetic contrast agent used in magnetic resonance imaging (MRI). It contains gadolinium, a rare earth metal, which shortens the relaxation time of nearby protons, enhancing the signal intensity and providing improved visualization of tissues and structures during MRI.
Gadodiamide 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
- Facilitate the visualization of lesions with abnormal vascularity within the thoracic, abdominal, pelvic cavities, and the retroperitoneal space
CNS :Adults and Pediatrics; 2-16 years of age: 0.2 mL/kg (0.1 mmol/kg)
Body: Adults and Pediatrics; 2-16 years of age:
- Kidney: 0.1 mL/kg (0.05 mmol/kg)
- Intrathoracic, intra-abdominal, and pelvic cavities: 0.2 mL/kg (0.1 mmol/kg)
Most Common Adverse Reactions:
- Headache
- Nausea
- Dizziness
- Injection site reactions (e.g., pain, warmth, and burning sensation)
Serious or life-threatening reactions include: cardiac failure, arrhythmia and myocardial infarction.
- Inadvertent intrathecal use of Gadodiamide has caused convulsions, coma, sensory and motor neurologic deficits.
-
Nephrogenic Systemic Fibrosis (NSF):
- Gadodiamide may increase the risk of NSF in patients with impaired renal function. Assess renal function before administration.
-
Hypersensitivity Reactions:
- Anaphylactic and anaphylactoid reactions, sometimes fatal, have been reported. Administer a test dose in patients with a history of allergy.
-
Renal Impairment:
- Gadodiamide is contraindicated in patients with acute kidney injury or chronic severe renal impairment.
-
Pregnancy and Lactation:
- Use Gadodiamide during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Contraindication
Gadodiamide is contraindicated in patients with hypersensitivity to gadolinium-based contrast agents.
Gadodiamide is contraindicated in patients with:s.
- Acute kidney injury
- chronic severe renal impairment (glomerular filtration rate <30 mL/min/1.73m²).
