What Is An MRI and Why It’s Done
Magnetic resonance imaging (MRI) is a technique that uses a magnetic field and radio waves to create detailed images of the organs and tissues within your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRI machine, the magnetic field temporarily realigns hydrogen atoms in your body. Radio waves cause these […]
MRI With and Without Contrast Explained
MRI with contrast is required when very detailed images for evaluating the problem are needed. A special tracer agent is injected into the vein of the patient during the MRI procedure. The decision whether to make an MRI with contrast depends on the type of the problem and also depends on the history of the given […]

What To Know About Head And Brain MRI Scans
Doctors use MRI scans to diagnose and monitor head injuries and to check for abnormalities in the head or brain. Magnetic resonance imaging (MRI) scans provide 3-D images of specific body parts. The scan produces highly detailed images from every angle. Depending on the purpose of the scan, a doctor may recommend contrast, which is […]
MRI To Study Heart Muscle Activity
An international team led by scientists from Lawson Health Research Institute and Cedars-Sinai Medical Center are the first to show that Magnetic Resonance Imaging (MRI) can be used to measure how the heart uses oxygen for both healthy patients and those with heart disease. Reduced blood flow to the heart muscle is the leading cause […]
What To Expect During Your MRI
What can I expect during my MRI scan? The duration of the procedure will vary but the average is 45 minutes to one hour per body part. You will be required to lie still during the actual MR scanning. Depending on the body part that is being examined, you may be instructed to hold your […]
Head MRI
What is a head MRI? Magnetic resonance imaging (MRI) of the head is a painless, noninvasive test that produces detailed images of your brain and brain stem. An MRI machine creates the images using a magnetic field and radio waves. This test is also known as a brain MRI or a cranial MRI. You will […]
Knee MRI
Causes for a knee MRI Your doctor may order an MRI scan if they suspect any abnormalities within your knee joint. The test helps your doctor visualize the anatomy of your knee to determine the possible cause of your pain, inflammation, or weakness, without having to do surgery. According to the Radiological Society of North America, […]
Lumbar MRI
What is a lumbar MRI? A lumbar MRI specifically examines the lumbar section of your spine — the region where back problems commonly originate. The lumbosacral spine is made up of the five lumbar vertebral bones (L1 thru L5), the sacrum (the bony “shield” at the bottom of your spine), and the coccyx (tailbone). The […]
Shoulder MRI
Why a shoulder MRI scan is performed The shoulder is a large and complicated joint that we use on a daily basis. It’s made up of three major bones. This makes it the most mobile joint in the body.
