How does Sesame have such competitive prices for MRIs?
What is an MRI used to diagnose?
MRI scans can be used to gather data on many areas of the body. The MRI allows your doctor to see organs, bones, and tissues in your body without surgery. This can help doctors diagnose a disease or injury. Some conditions an MRI scan may help find are:
Signs of a stroke
Spinal disk problems
Bone and joint injuries
Internal organ health
Soft tissue inflammation
What happens during an MRI?
An MRI scanner is operated by a radiologic technologist and is used for the imaging of a certain part of the body. You can speak to your technologist during the procedure via a microphone in the machine. If you have a history of claustrophobia, you may be given a sedative drug to relieve anxiety during the procedure.
Once you are in the MRI machine, a strong magnetic field is created around you or the part of the body being scanned. The procedure is completely painless. The protons in your body, or in the specific area of your body, will line up in a single direction. Short bursts of radio waves will be directed at your body, or a specific area of your body, that will cause these protons to emit radio signals. These signals are then combined like pixels on a computer screen to create detailed imaging of tissue, bone, and organs inside your body.
In some cases, a contrasting agent may be injected through your veins to enhance visual details in your scan. Gadolinium is the most frequently used contrast agent for MRI scans. Side effects of gadolinium are mild but may produce a chilling effect at the injection site or a “pins and needles” feeling. Sesame offers MRI procedures with and without contrast.
The scan can last anywhere from 15 to 90 minutes, depending on need, and how many images must be collected. The internal part of the magnet produces noise that can be blocked out with earplugs or music played during the procedure. Connect with doctors on Sesame to determine the MRI procedure that works best for you.
What are contrast agents?
Contrast agents are dyes used to help the clarity of scanned images. They are usually swallowed, or injected into a vein.
The most common contrast agents used by radiologists are:
- Barium-sulfate materials
These dyes are safe but have been known to cause mild allergic reactions in some cases. Severe reactions are rare.
Tell your doctor in advance about the following:
- Any food, dye, preservative, or drug allergies
- Medications you are taking, including herbal supplement
- Recent illness
- Any medical history of heart disease, asthma, diabetes, or hayfever
- History of kidney and liver problems or disease
How should I prepare for an MRI?
Prior to an MRI scan, a patient may be able to eat and drink normally, while taking their usual medication, unless advised otherwise. In certain cases, you may be asked not to drink water for up to four hours before the scan; in other cases, you may be asked to hydrate before receiving the contrast agent. These conditions depend on the area of the body being scanned, and the reason for scanning.
During your MRI, you may be asked to disrobe and change into a hospital gown prior to your scan. Additionally, you may be asked to remove any metal objects that might interfere with the MRI scan such as:
Wigs (as some wigs contain traces of metal)
