Gadolinium is the most commonly used MRI contrast agent used today. It is considered to be safe when administered properly and is capable of detecting tumors or blood vessel issues.
A CT Scan can image an aneurysm without a contrast injection even though it does better with a contrast agent. An MRI will require an contrast agent or an MRI/MRA.
No. Some doctors will order MRI with contrast to facilitate better imaging of some body structures. It is not absolutely necessary to have an IV for an MRI but if your doctor believes it is beneficial to have a the MRI with contrast then it best to consent and have the IV.
No, usually contrast agents are not used for MRI of the spine. The most frequent pathology when an spine MRI is requested si discal hernia (lombosciatic, disc protrusion). Then another pathology is searched and/or discovered (tumors, bone lesions), than contrast agent is required for a correct diagnosis.
If they are doing a contrast dye scan, they usually use a form of iodine as the contrast agent. This dye agent is used regardless of which part of the body is being scanned.
MRI uses high magnetic fields and radio frequency and not x-ray. The procedure is generally safe and typically repeated examinations do not cause any problems. However, some MRI scans use a Gadolinium-based contrast agent, so repeating MRI scans within a few days may expose a patient to higher-than-expected levels of the contrast agent in the blood, which can be affected by kidney function. Patients should check with their doctor before having a repeat contrast MRI scan within a few days.
An MRI with contrast means that a person who is getting the MRI will be given a dye or other medication which will show better what part the doctor is interested in.
The contrast agent will be injected into the spinal canal between the disc nearest to the area to be examined - you'll need to ask your doctor or the technician for a more precise answer . (For me , it was uncomfortable but not any more painful than getting a shot .)

MRI exams can be done: 1. Without contrast (dye) 2. With contrast (dye) 3. With and without contrast (dye) The majority of MRI exams are done without contrast. Most common reasons for contrast administration include infection, cancer, and after surgery. FDA approved contrast agents are gadolinium based and are safe to use in patients. However, they can have very harmful side effects if the patient develops an allergic reaction or has kidney disease or kidney failure. Without functional kidneys, the body cannot get rid of the gadolinium from the contrast agent, which can cause a deadly and incurable disease known as nephrogenic systemic fibrosis.
MRI, or Magnetic Resonance Imaging, is an imaging technique using a very powerful magnet and sophisticated detectors or 'scanners' to obtain very detailed images of any part of the body. There is no radiation or x-rays involved. The MRI can be non-contrast, contrast, or both. If both, the non-contrast proceedure is done first. No matter what part of the body is being imaged, the contrast is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and then the liquid contrast material is injected, and the MRI performed.
If contrast is going to be usedduring the MRI, kidney function must be adequate to filter the contrast. If they are compromised the contrast can cause a serious disease.
