An MRI scan uses a strong magnetic field, radio waves, and a computer to create detailed images inside the body. This technique diagnoses various medical conditions.
Safe Items During MRI
Wearing a Pad
Can you wear a pad during an MRI? Yes, it’s safe to wear a pad. The magnetic field won’t affect the pad. However, it’s important to inform healthcare providers about wearing pads, as they may provide instructions on removal before the scan.
MRI Equipment and Procedure
Types of MRI Machines
Today, there are closed and open MRI machines. Patients can be scanned sitting, standing or lying down with an Upright MRI. Other MRIs require laying down.
MRI Process
During MRI, patients lie inside a large metal unit. Scans last 15 to 90 minutes depending on the area scanned and images taken. Patients can communicate with technicians and stop the scan anytime.
Specific MRI Applications
MRI in Medical Research
Jeff Zhang examines muscle tissue perfusion in PAD patients. Like cardiac patients, PAD patients experience “arterial steal,” where areas near blockages “steal” blood flow.
Knee MRI
Knee fat pads can become impinged, causing pain and inflammation. MRI helps evaluate impingement to guide treatment.
MR Enterography
MR enterography uses MRI with contrast to produce detailed small intestine images. The MRI results are usually interpreted within 24 hours. Patients typically receive the scans on a disc after the MRI.
MRI for Blood Clots
MRI can identify blood clots with precision by showing anatomical images, measuring blood flow, or revealing mineral deposits.
MRI Preparation
It’s recommended to refrain from wearing perfumes and deodorant on your underarms and chest area before an MRI scan. You may be asked to wear a hospital gown or clothing without metal fasteners. Preparation for an MRI is simple – maintain your regular routine for eating, drinking and medication. On scan day, follow doctor’s instructions. Yes, you can brush your teeth beforehand.
MRI and Arteries
Magnetic Resonance Angiography (MRA)
Magnetic resonance angiography (MRA) uses MRI techniques to image blood vessels and identify abnormalities like stenosis, aneurysms, or occlusions. MRA often evaluates arteries in the neck, brain, legs and more without using contrast agents.
