Magnetic resonance imaging (MRI) of the spine uses radio waves, a magnetic field and a computer. It creates clear, detailed pictures of the spine and surrounding tissues. MRI does not use radiation and may require an injection of gadolinium contrast material.
When do you need an MRI without contrast?
Non-contrast MRI is great option for patients for whom dye is not recommended, pregnant women and kidney-compromised patients. Non-contrast also provides greater images of blood vessel activity, detecting aneurysms and blocked blood vessels.
Can I have MRI without contrast?
The majority of MRI exams are done without contrast. Due to the detail seen on an MRI, the contrast is not needed to diagnose most diseases or injuries. However, in some cases, contrast is used to help in the diagnostic process.

Does a pelvic MRI need contrast?
This coil must stay in place for about 30 minutes while the images are taken. Some exams require a special dye, called contrast media. The dye is most often given before the test through a vein (IV) in your hand or forearm. The dye helps the radiologist see certain areas more clearly.
What should I do the night before my MRI?
Before an MRI exam, eat normally and continue to take your usual medications, unless otherwise instructed. You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as: Jewelry. Hairpins.
Can aneurysms be detected without contrast in MRI?
Possibly: They are mr sequences (protocols) that can be used to detect aneurysm without contrast injection. But small aneurysms can be missed.
What are the advantages of MRI for evaluation of cerebral aneurysms?
The use of MRI for evaluation of cerebral aneurysms is continually and rapidly evolving. MRI has advantages over CTA in that it does not use ionizing radiation and offers the ability to obtain images without the need for administration of intravenous contrast agents.
What does an MRA scan of left ophthalmic artery aneurysms show?
MRA scan of aneurysms. a Axial TOF MRA demonstrates a left ophthalmic artery aneurysm ( arrow ). Although it avoids the use of contrast, the longer acquisition time introduces some motion artifact. b Contrast-enhanced axial MRA in the same patient with less motion artifact of the aneurysm ( arrow)
What does an MRI scan of the lumbar spine show?
An MRI scan provides a different kind of image from other imaging tests like X-rays, ultrasound, or CT scans. An MRI of the lumbar spine shows the bones, disks, spinal cord, and the spaces between the vertebral bones where nerves pass through. Unlike an X-ray or CT scan, an MRI doesn’t use ionizing radiation.
