MRI Brain With Contrast is an imaging procedure which uses a magnetic field, radio pulses, and computer programs to create highly detailed views of the internal structure of the brain. (1)
What is MRI Brain With Contrast?
MRI Brain With Contrast is an important tool for detecting disorders in small structures of the brain, which are not clearly visible in x-rays and CT scans. It is useful in the diagnosis of aneurysms, multiple sclerosis, hydrocephalus, tumors, cysts, inflammation, infection, and internal bleeding in the brain. (1)
How is MRI Brain With Contrast Performed?
It is a non-invasive procedure.
- Patient has to lie down on the examination table with arms placed on the sides.
- An IV is inserted to inject sedation, pain medication and contrast.
- Coils that generate and detect radio pulses are placed around the head, to increase the quality of the images.
- The table slides inside the MRI magnetic field, where multiple images of the brain are produced.
- Gadolinium contrast solution is injected through the IV.
- Another series of images are captured as the contrast passes through the brain.
The test is performed in multiple sequences. It takes around 60 minutes.
Side-effects of MRI Brain With Contrast Test
It is a safe procedure as it does not use x-rays or ionizing radiation.
- Allergy to the contrast.
- The contrast may further damage the kidneys of patients suffering from kidney disorders.
- Some metal implants may malfunction during the procedure.
- Pain or bruising at the site of IV.
Preparation before Performing MRI Brain With Contrast
It is a painless procedure that can be performed on an out-patient basis. Prior preparation involves
- Inform allergies, metal implants and other health conditions to the doctor.
- Discuss food and medication before the test with your doctor.
Post-care after MRI Brain With Contrast
MRI Brain With Contrast does not require much post-care.
- The patient can go home immediately after the test.
- Patients with sedation during the test are kept under observation for some time after the test.
- Drink plenty of fluids to flush out the contrast.
