Everything You Need to Know About MRI Exams

Patients experiencing complex conditions may be referred for MRI exams. This article offers detailed information about the MRI exam procedure, its benefits, and what to consider. MRI (Magnetic Resonance Imaging) is an advanced imaging technique commonly used to assess spine and joint concerns. It is often a crucial step in identifying the root cause of a condition.

Understanding MRI Exams

At times, our chiropractors may recommend an MRI (Magnetic Resonance Imaging) to accurately evaluate your condition. This exam uses magnetic fields and radio waves to capture detailed images, offering a clearer view of the area being examined compared to traditional X-rays, CT scans, or ultrasounds. If you’re experiencing discomfort and need a precise diagnosis, reach out to our center. Chiropractic Specialty Center® provides exceptional care, including thorough diagnostic assessments.

Why Might You Need an MRI Exam?

Accurate diagnosis is a key part of effective care. However, many individuals are diagnosed hastily and treated without comprehensive diagnostic imaging. At Chiropractic Specialty Center®, we are committed to finding the root cause of your condition before starting treatment. We take pride in our thorough diagnostic process, ensuring we fully understand your condition.

If necessary, we may recommend an MRI or X-ray to document the underlying cause of your discomfort. We offer comprehensive spine and joint care, but before initiating care, an MRI might be required. Our clinical team will advise you accordingly.

MRI imaging is highly effective for visualizing soft tissues like ligaments, cartilage, spinal discs, muscles, bursae, and tendons. It is especially useful for evaluating conditions like frozen shoulder (adhesive capsulitis), herniated discs, disc bulge, knee pain, hip pain, shoulder injuries, and even conditions like migraines or Tarlov cysts.

Magnetic Resonance Imaging provides detailed, three-dimensional images of the targeted region in multiple planes (coronal, sagittal, and axial). It uses high magnetic fields combined with advanced computer software to produce precise images.

Are There Different Types of MRI Scanners?

There are two types of MRI scanners: weight-bearing and non-weight-bearing scanners. Weight-bearing MRI scanners are relatively new and allow better assessment of the spine and joints in a seated or standing position. Unfortunately, weight-bearing MRI scanners are not available in Malaysia. Therefore, we will focus on non-weight-bearing MRI scanners.

Non-weight-bearing MRI scanners come in two main types: open-sided MRI scanners and closed MRI scanners. Open MRI scanners are better suited for patients who are larger or have claustrophobia, as they have a more open design. However, the image quality of open MRI scanners may not be as clear as that of closed MRI scanners. Regardless of the type of MRI, you will be required to lie down in a supine (face-up) position. The MRI technician will assist you in getting comfortably positioned before slowly sliding the bed into the scanner.

What to Do When Preparing for an MRI

During your MRI exam, it is essential to remove all metal objects before entering the scanner. Items such as watches, jewelry, hearing aids, dentures, and any metal objects must be removed to ensure safety during the scan, as the MRI uses a powerful magnet. If you have any metallic implants, including stents, pacemakers, defibrillators, or heart valves, please inform your chiropractor or the MRI technician beforehand. If you have dental work such as braces or other metallic implants, these details should also be shared with the medical professionals conducting the MRI.

If you feel anxious about being in a confined space, speak with your chiropractor before the exam. In some cases, a mild sedative may be recommended to help you relax during the procedure. Open MRIs are available at some locations and may be a viable alternative if you experience discomfort in confined spaces.

What to Expect Before and During the MRI Exam

Before undergoing the MRI, you will likely be required to sign a consent form acknowledging your understanding of the procedure. Once inside the MRI scanner, you may hear some noises such as a fan or occasional snapping sounds as images are taken. Some centers provide music or earplugs to help minimize the noise.

During the exam, the MRI technician will monitor you through a window and you will be able to communicate via an intercom system. If contrast material is required for the scan, it will be administered through an intravenous line in your arm. This process typically takes one to two minutes. The duration of the MRI scan can range from 30 minutes to an hour, though some exams may take up to two hours depending on the complexity.

What Does It Feel Like to Take an MRI?

The MRI process itself is not painful. You will be asked to lie on a firm table and remain still for extended periods, which may be uncomfortable but not painful. In some cases, you may feel a slight chill, or you might become fatigued from staying in one position for a long time.

People with metal dental fillings might experience a slight tingling sensation in their mouth, but this is generally not a cause for concern. If you experience dizziness, nausea, a burning sensation, difficulty breathing, or headaches during the exam, inform the MRI technician immediately.

Is Radiation or Other Harmful Effects Associated with MRI Exams?

Unlike other forms of diagnostic imaging, MRI exams do not emit any radiation. MRI assessments are generally considered safe, with no known harmful effects associated with the procedure. However, the strong magnetic field generated by MRI imaging may interfere with metallic implants such as pacemakers, metal clips, or metallic prostheses. It is important to inform your healthcare provider and MRI technician if you have any metal implants in your body.

Welders and factory workers who are exposed to fine metal particles should take extra precautions before undergoing an MRI, as metal fragments in tissues or eyes could interfere with the scan. In such cases, x-rays may be performed to check for metal fragments prior to an MRI exam. Always communicate your work history and any concerns with your healthcare provider and the MRI technician to ensure safety.

MRI exams are typically very safe when proper safety measures and protocols are followed. However, the effects of the magnetic fields used in MRI exams are not fully understood, and further research is needed in this area. Despite this, MRI scans are considered much safer than x-rays or bone scans and are often regarded as the gold standard for diagnosing spine and joint conditions.

Should You Be Concerned About the Magnetic Fields?

While some individuals may have concerns about the magnetic fields used in MRI, there are no known negative health effects. However, if you have metal fragments in your eyes, you should not undergo an MRI. Additionally, some tattoo pigments may contain iron, which could cause irritation during the scan.

There is a very slight chance of an allergic reaction to the contrast dye used in some MRI exams, but such reactions are typically mild. If you are breastfeeding and concerned about the contrast dye, consult with us beforehand. In such cases, you can express milk before the test and store it for use, as the dye will be cleared from your body within a few days.
