When should I get an MRI?

An MRI is commonly warranted when there’s a need to view detailed images of soft tissues, such as cartilage and ligaments. MRI technology does this better than CT scans. This allows your provider to pick up problems that may be invisible using other imaging technology.

What is alternative to MRI?

“An MRI is the gold standard for some studies,” Shaver says, “but if someone has an implant or other condition that would preclude them from having an MRI, the alternative is a CT scan. In the past, the CT scan resulted in lower-quality images, and the dose of radiation was higher.”

Can MRI results be seen immediately?

This means it’s unlikely you’ll get the results of your scan immediately. The radiologist will send a report to the doctor who arranged the scan, who will discuss the results with you. It usually takes a week or two for the results of an MRI scan to come through, unless they’re needed urgently.

What if my MRI showed nothing?

The bottom line is that not all pain is able to be detected on an x-ray or MRI. That does not mean that there is nothing there that needs to be treated or diagnosed. In fact, it means that it is possibly a precursor to something going really wrong and then eventually needing surgery because it eventually winds up torn.

Does Stress Show on MRI?

Striking results emerged in the first set of MRI scans taken after just three days of stress — the hippocampus of every stressed rat had shrunk. “It was a totally unexpected result. Normally structural changes are seen in the brain after a long time — say 10 to 20 days.

How can I get my doctor to give me an MRI?

If your primary care doctor thinks you should have an MRI, his or her office staff will call to schedule an appointment for you. Many insurance companies require office staff to call on your behalf to get the scan approved. You will go to a hospital or radiology center for the scan.

MRI is not painful, but the patient must remain still in an enclosed machine, which may be a problem for claustrophobic patients.

What are the side effects of an MRI?

The magnetic fields that change with time create loud knocking noises which may harm hearing if adequate ear protection is not used. They may also cause peripheral muscle or nerve stimulation that may feel like a twitching sensation. The radiofrequency energy used during the MRI scan could lead to heating of the body.

How quickly will doctor call with MRI results?

The swift transmission of diagnostic information is important to both patients and referring physicians. The results from an MRI scan are typically interpreted within 24 hours, and the scans themselves are usually given immediately to the patient on a disc after the MRI is complete.

Why metals are not allowed in MRI scan?

MRI imaging is quite safe for human tissue, but introducing metal near the machines can be deadly. … It’s that strong magnetic field that can prove dangerous if there’s any metal in the room when the machine is switched on, as the magnet will yank metal objects toward it.

What happens if you move during an MRI?

She began her presentation by stating that “one of the most important problems in magnetic resonance imaging is motion.” When patients move during an MRI, they create motion artifacts in magnetic resonance images that often appear as ghosting artifacts, obscuring clinical information.

Can you fall asleep in an MRI?

It’s important that every patient knows they are safe around and inside an MRI. If you’re like me, you may even fall asleep during the exam.

Can you have an MRI if you have braces?

Are MRIs harmful to the body?
