MRA scan of head with and without contrast

Procedure Information

What is a MRA Scan of Head with and without Contrast?

A MRA scan of head with and without contrast is a type of imaging test that uses a large magnet, radio waves, and a computer to produce detailed pictures of the brain. This procedure uses contrast dye to collect data on the brain’s tissues and blood vessels.

Why Would I Get a MRA Scan of Head with and Without Contrast?

A MRA scan of head with and without contrast is typically used to detect the presence of brain tumors, aneurysms, stroke or injury, or to observe the effects of a medical condition on the brain.

What Happens During a MRA Scan of Head with and Without Contrast?

During the procedure, the patient lies on a table and a large circular device (known as a magnet) will produce a magnetic field around their head. This magnet works in conjunction with a computer to produce 3D images on a display monitor. Depending on the patient’s needs, the contrast dye can then be administered before the second scan. This dye contains certain elements, like gadolinium, that allow for more detailed imaging.

What to Expect After a MRA Scan of Head with and Without Contrast?

In most cases, the patient can return to their normal activities following the procedure. Depending on the results, the patient’s doctor may decide to order follow up tests, diet changes, or medications to treat the underlying condition.

Conclusion

A MRA scan of head with and without contrast is an imaging test that uses powerful magnets, radio waves, and a computer to produce detailed pictures of the brain. The contrast dye is used to improve the detail of the picture, and the procedure usually takes up to an hour. After the scan, the patient can return to their normal activities. If the results show the presence of certain conditions, the doctor may order follow up tests or make lifestyle changes.
