Open MRI in Houston: What to Know

If you have ever felt anxious about getting an MRI, you are not alone. Studies suggest that 5% to 15% of patients experience significant claustrophobia during MRI scans, and many more report discomfort in the tight bore of a standard closed system. Open MRI scanners address this by providing a wider, less enclosed scanning environment. In Houston, Mira offers open MRI in Houston, with scans starting from $369.

What Is an Open MRI?

An open MRI scanner differs from a traditional closed-bore MRI in its physical design. A standard closed-bore MRI is a long, narrow tube that surrounds the patient on all sides. The bore is typically 60 cm (about 24 inches) in diameter. For many patients, this tight space triggers anxiety, claustrophobia, or panic.

An open MRI has a wider opening and is not fully enclosed. Some designs are open on two or three sides. Others use a wide-bore configuration that keeps the cylindrical shape but increases the diameter to 70 cm or more. Both approaches give the patient more room and a less confined feeling during the scan.

The trade-off historically was image quality. Older open MRI systems used lower-field magnets (0.2T to 0.7T) that produced lower-resolution images. Modern open and open-bore systems, including the ones at Mira Scanning Center in Houston, use stronger magnets that produce diagnostic-quality images comparable to closed-bore systems for most clinical applications.

Open MRI vs Closed MRI: Key Differences

For the majority of diagnostic MRI scans (knees, shoulders, brain, spine, abdomen), modern open MRI systems produce images that are more than adequate for diagnosis. Your radiologist will let you know if a particular scan requires a higher-field closed-bore system.

Where to Get an Open MRI in Houston

Through Mira, you can get an open MRI at two Houston-area locations. The primary open MRI option is at Mira Scanning Center, Walters Road.

Mira Scanning Center, Walters Road - Spring (Primary Open MRI Location)

Address: 14405 Walters Rd, Suite A, Houston, TX 77014. This is the best open MRI location in the Mira network. It offers both an open MRI scanner and a high-field MRI scanner, giving patients and physicians the flexibility to choose the right system for each scan.

The 350 lb weight capacity at this location accommodates patients who cannot use the 275 lb limit of a standard closed-bore system. The open design also makes the scan significantly more comfortable for patients with broad shoulders or larger frames who find standard-width bores uncomfortable.

What about the other Houston locations?

Richmond Ave and Dickinson both use closed scanners, so neither is an option if claustrophobia is the reason you are looking for open MRI. Dickinson runs a 3T, which gives the sharpest images of the three, and MRI there is available on Thursdays only. If you need an open scanner, Walters Road is the location to book.

Who Should Consider an Open MRI?

Open MRI is not just for patients with claustrophobia. Several groups of patients benefit from the wider, more open design.

• Patients with claustrophobia or anxiety: The open design reduces the feeling of confinement. Many patients who could not complete a closed-bore scan are able to finish an open MRI without sedation.
• Larger patients: Standard closed-bore MRI scanners have weight limits of 250 to 300 lbs and bore widths of about 60 cm. Patients who exceed these limits need an open or wide-bore option. The Spring location accommodates up to 350 lbs.
• Patients with broad shoulders or large frames: Even patients under the weight limit may find a standard bore too tight. Open MRI provides more physical room.
• Children: Some children find the open design less frightening than a full-enclosure system.
• Patients who need a companion nearby: Some open MRI designs allow a family member or caregiver to stand closer to the patient during the scan.
• Patients who tried a closed MRI and could not complete it: If you have had a previous MRI that was cut short due to anxiety, an open MRI is a practical alternative.

Open MRI Cost in Houston

At some facilities, open MRI scans carry a premium over closed-bore scans because the scan may take longer or because the facility wants to recover the cost of specialized equipment. Through Mira, open MRI starts from $369, the same cash pay rate as a standard diagnostic MRI.

Many patients assume that open MRI costs more because it is a specialized service. At Mira, that is not the case. The cash pay pricing is transparent and consistent: from $369 for a diagnostic scan at any location, including the open MRI at Spring.

What to Expect During an Open MRI Scan

The scan itself is similar to a closed-bore MRI in terms of what you need to do as a patient. Here is what to expect at Mira Scanning Center, Walters Road.

• You will fill out a safety screening questionnaire to check for metal implants, pacemakers, or other contraindications.
• You will change into a gown and remove all metal items (jewelry, watches, belt buckles, etc.).
• The technologist will position you on the MRI table and place a coil over the body part being scanned.
• You will lie still during the scan, which takes 30 to 60 minutes depending on the body part.
• You will hear loud knocking and buzzing sounds. Earplugs or headphones are provided.
• The technologist can communicate with you throughout the scan via an intercom system.

The key difference from a closed-bore scan is the feeling of space around you. In an open MRI, you are not enclosed in a narrow tube. The sides are open, and there is more air circulation. For patients who experience claustrophobia, this difference is significant.

Tips for Managing Claustrophobia During an MRI

Even with an open MRI, some patients still feel anxious. Here are strategies that help.

• Choose an open MRI scanner. This is the single most effective step for claustrophobic patients.
• Ask about the scan duration before you start. Knowing how long it will take helps you mentally prepare.
• Use deep breathing exercises. Slow, steady breathing reduces anxiety and helps you stay still.
• Keep your eyes closed if the open space still feels uncomfortable. Some patients find it easier to relax with their eyes shut.
• Ask the technologist for a panic button or squeeze ball. You can stop the scan at any time if needed.
• Talk to your doctor about mild sedation if previous MRI attempts have been unsuccessful. Oral sedation (like a low-dose benzodiazepine) can be prescribed ahead of time.
• Listen to music or a podcast if the facility allows headphones. Sound helps distract from the scanning noise.

Image Quality: Is Open MRI as Good as Closed MRI?

This is the most common question patients ask. The answer depends on the specific scanner and the specific scan being performed.

Modern open and open-bore MRI systems at the 1.0T to 1.5T level produce diagnostic-quality images that are sufficient for the vast majority of clinical indications. Knees, shoulders, brains, spines, and abdomens are routinely scanned on open systems with excellent results.

The cases where a 3T closed-bore system has a meaningful advantage are relatively narrow: certain neurovascular studies, some cardiac imaging protocols, and very small anatomical structures where the highest possible resolution matters. For standard diagnostic imaging, the difference between a 1.5T open-bore and a 1.5T closed-bore is minimal.

At Mira Scanning Center, Walters Road, the combination of open MRI and high-field MRI scanners means that the technologist and radiologist can select the right scanner for each patient and each clinical indication. You get the comfort of the open system when it is appropriate and the resolution of the high-field system when the scan demands it.

Scans Available on the Open MRI at Spring

The open MRI scanner at Mira Scanning Center, Walters Road supports a wide range of diagnostic scans. Common scans performed on the open system include the following.

• Knee MRI (ACL, meniscus, cartilage injuries)
• Shoulder MRI (rotator cuff tears, labrum tears, impingement)
• Brain MRI (headaches, dizziness, neurological symptoms)
• Lumbar spine MRI (lower back pain, sciatica, disc herniation)
• Cervical spine MRI (neck pain, nerve compression)
• Hip MRI (joint pain, labral tears, arthritis evaluation)
• Ankle and foot MRI (sprains, stress fractures, tendon injuries)
• Abdomen and pelvis MRI

Breast MRI is not available at the Spring location. If you need breast MRI, the Dickinson location in the Clear Lake area offers it exclusively on Thursdays. For scans that require the highest possible resolution (certain neurovascular studies, for example), the high-field scanner at the same Spring facility may be used instead of the open system.
