Radiology Ltd. is pleased to be the first in Tucson to share this new quantitative brain image analysis tool, which brings accurate and fully automated advanced MRI capabilities to you. NeuroQuant® is a powerful tool useful in the evaluation of patients from ages 18 to 95, providing critical information used in the assessment of neurological conditions such as: Alzheimer’s disease, epilepsy, multiple sclerosis and traumatic brain injury.
NeuroQuant® takes a high-resolution 3D T1-weighted sagittal, non-contrast-enhanced MRI scan, adjusts and aligns the images to a standard brain atlas, then identifies and segments multiple brain structures. It then measures their volumes and compares the volumes to a normative database adjusted for age, sex and cranial volume.
You will be asked not to eat for 2 hours prior to the procedure. Please do not wear any jewelry or metal, and please do not wear make-up or use hair products.
You will not be able to have an MRI examination if you have any of the following:
- Most pacemakers
- Certain brain aneurysm clips
- Cochlear implants
- Metallic fragments in an eye
- Implanted spinal cord stimulator
- Certain other metal-containing implants
Some exams require injection of a contrast agent into a vein in your hand or arm to improve visualization of abnormalities on the MRI images. MRI contrast is an organically bound gadolinium-based material that is extremely safe and typically has no side effects, though there is always the potential for allergic reaction. Please let us know if:
- You are pregnant or think you might be
- You are breast feeding
- You have anemia or any diseases that affect red blood cells
- You have asthma or other allergic respiratory disorders
- You have kidney (renal) disease
- You have a history of injury during military service
- You have a history of working with metal
After you arrive for your appointment, you will be escorted to a procedure room, where you will be asked to change into a patient gown. The technologist will position you on a cushioned table that will move into the tube-shaped scanner. After you have been properly positioned, the technologist will begin obtaining the MRI images.
The MRI machine creates a magnetic field around you and directs radio waves at your body to create the MRI images. You won't feel the magnetic field or radio waves, but you may hear loud tapping and thumping sounds coming from inside the machine. While the images are obtained, you will be instructed to breathe normally but to lie as still as possible. The technologist will monitor you from another room. You will be able to speak to the technologist through a microphone, and the technologist will also be able to talk to you. Most exams take from 30 to 60 minutes, after which you will be able to return to your normal activities.
For your safety and the protection of others, we do not allow anybody except patients in our exam rooms.
