What is the difference between MRI and MRI with contrast?
The primary difference is that for contrast MRIs, a dye (gadolinium-based) is given to the patient intravenously prior to the scan.
Non-contrast MRI is great option for patients for whom dye is not recommended, pregnant women and kidney-compromised patients..
How long does an MRI with contrast take?
The test normally takes 30 to 60 minutes. You may receive a contrast solution, usually gadolinium, through an IV to allow the MRI machine to see certain parts of your brain more easily, particularly your blood vessels. The MRI scanner will make loud banging noises during the procedure.
Which MRI scans require contrast?
MRI contrast is required when a very detailed image is necessary to evaluate the problem area of the body. Gadolinium contrast is used in about one in three MRI scans, to improve the diagnostic accuracy of the scan.
Is it safe to have MRI with contrast?
Gadolinium contrast agents have been used in hundreds of thousands of patients over the past couple decades and the clinical evidence shows it is safe in most patients, Wintermark said. Until the past few years, it was not widely known that the gadolinium accumulated and was retained in tissues, especially the brain.
How much water should I drink after an MRI with contrast?
If you had intravenous contrast, you should drink at least eight glasses of water throughout the day to help flush the contrast out of your body. Your doctor will receive the results within 48 hours.

Is contrast dye necessary for MRI?
Typically injected into a vein in the hand or arm during the scan, contrast is used to enhance the appearance of certain structures within the body. Dyes are not always essential – when looking at bones, ligaments and tendons, contrast dyes are rarely needed.
Why do I feel weird after an MRI?
According to researchers at John’s Hopkins University, the magnet in MRI machines can stimulate the inner ear’s balance center, causing some patients to feel vertigo while they are inside the machine and in the minute or two after they’ve left it.

What can a brain MRI with contrast detect?
MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headache. Figure 1. MRI of the brain.
What should I do before an MRI with contrast?
On the day of your MRI scan, you should be able to eat, drink and take any medication as usual, unless you’re advised otherwise.

What does it mean to have an MRI with contrast?
A contrast MRI occurs only when ordered and approved by a patient’s physician. This means that a gadolinium-based “dye” will be injected into the patient’s arm intravenously. This contrast medium will enhance the image quality, allowing the radiologist to be more accurate and confident in their diagnosis.
How long does contrast stay in your system?
With normal kidney function, most of the gadolinium is removed from your body in the urine within 24 hours. If you have acute renal failure or severe chronic kidney disease and receive a gadolinium-based contrast agent, there may be a very small risk of developing a rare condition.
What are the side effects of MRI contrast dye?
The most common side effects of headache, nausea and dizziness occur in a small minority of patients only, but if they do occur they will be noticed within minutes of the injection.
