MRI Basics and Frequent Questions

MRI Basics and Frequent Questions

MRI technology has substantially improved in the past few years. A new generation of MRI devices and additional technological advances such as contrast enhancement and special processing are being used together to generate amazingly clear images.

Today we will attempt to answer some of the questions and concerns about magnetic resonance imaging or MRI.

MRI or magnetic resonance imaging, is one way of viewing the body that uses NO radiation as it uses the electromagnetic properties of hydrogen molecules to collect information about organs and other tissues and converts this to an image. An MRI is able to capture the differences between cancerous tissues and normal tissues.

Having an MRI involves being positioned on a table and moved inside the MRI unit. The inside of the MRI is called the bore and is basically a long tube the size of which varies. We center the body part being evaluated within the bore.  An MRI exam takes 45 minutes to a little over an hour.

Before undergoing an MRI, your doctor will ask whether you have any electronic or metal medical devices in your body, such as a heart pacemaker or any metallic clips, pins, or screws. These precautions are necessary because the MRI magnet is so powerful that it could interfere with a pacemaker or displace some implanted clips. We will be posting more about MRI safety in future posts.
