Diagnostic Imaging & Clinical Research located in Houston, TX

Of all the different types of diagnostic imaging, magnetic resonance imaging (MRI) is the best choice for creating detailed pictures of soft tissues. And since MRIs don’t rely on X-rays, you don’t need to worry about radiation. Ebrahim Delpassand, MD, and the team at Excel Diagnostics & Nuclear Oncology Center are experts in whole-body and targeted MRI imaging, producing pictures that can diagnose a wide range of problems. If you have questions or need to schedule an MRI, call the office in Houston, Texas, or book an appointment online today.


How does MRI work?

Magnetic resonance imaging or MRI combines computer-generated radiofrequency waves with a strong magnetic field to create exceptionally clear and detailed images of your internal organs and tissues. The technology an MRI uses detects changes or movement in molecules and turns that information into pictures. 

The MRI machine takes cross-sectional images from many directions, top to bottom, side to side, and front to back. Then the computer assembles different slices to make three-dimensional images. That allows the team to customize your MRI and focus on a specific area or to include your whole body if needed. 

When might I need an MRI?

An MRI shows details you can’t get from X-rays and other types of diagnostic imaging. The team at Excel Diagnostics & Nuclear Oncology Center uses MRIs to produce images of every part of your body. 

Your referring doctor, whether your primary care physician or a specialist, may recommend an MRI to diagnose many different health conditions, including:

  • Cancers
  • Strokes
  • Brain tumors
  • Heart disease
  • Vascular disease
  • Multiple sclerosis
  • Spinal cord disorders
  • Masses in soft tissues
  • Musculoskeletal disorders and injuries

Since an MRI can show clear pictures of soft tissues near and around bone, it’s the most sensitive type of imaging for diagnosing spine and joint problems.

How do I prepare for an MRI?

You don’t need to do anything to prepare for a standard MRI. You only need to wear comfortable clothes that don’t contain metal, like sweatpants. The team can also give you a gown, and you can use a private dressing room to change. You should take your usual prescribed medications.

During some MRIs, the team injects a contrast dye so they can get a better view of certain structures. The team talks with you ahead of time if your scan involves contrast and lets you know how to prepare. For example, you may not be able to eat or drink in the hours before your scan.

What should I expect during an MRI?

You lie down on a comfortable, padded table, and the table slides into a tunnel in the center of the MRI machine. It’s essential to stay entirely still during each imaging sequence. At times, your technician may ask you to hold your breath for a short time. If you move, the images may look distorted.

You should be prepared to hear loud thumping noises or knocking sounds during the MRI. It is normal while the magnet works. If the noise is uncomfortable, the team can give you headphones to wear.

Though the MRI technician doesn’t stay in the room, you can talk to them at any time during your exam if you have a concern or question. A typical MRI takes about 20-30 minutes. However, your time may vary, depending on the specific image you need.
