When it comes to health issues, MRI scans are often the go-to method for assessing the problem. They can help diagnose all kinds of conditions from muscle tears to brain abnormalities. But what happens if you have sternal wires? Can you still get an MRI done? Well, the answer is not as straightforward as you might think.
Sternal wires are commonly used to bring together the bones in the sternum after certain surgeries, such as open-heart procedures. But they can sometimes cause issues when it comes to medical imaging. You might be wondering why that is, and the fact is that these wires can interfere with the magnetic field generated by the MRI machine. This can potentially lead to inaccurate or distorted images, making it challenging or even impossible for professionals to diagnose a condition accurately. So, can you still get an MRI with sternal wires? Let’s explore this question in more detail.
If you or someone you know has sternal wires and is in need of an MRI, it’s essential to understand the risks and complications involved. While an MRI can sometimes still be done, your doctor will need to consider a few factors first. For instance, the size, positioning, and type of wires used can all affect whether or not you can get an MRI. It’s best to discuss your options with a specialist to see what the best course of action is. So, while you might be able to get an MRI with sternal wires, it’s not always a straightforward process.
What are sternal wires?
When you undergo a sternotomy, which is a surgical procedure that involves splitting open your chest bone to access your heart or lungs, sternal wires are used to hold the bone in place during the healing process. These wires are thin, strong metallic threads that are wrapped around the two halves of your breastbone to keep them together as they grow back together. The sternum needs to be held in place to make sure that it heals properly after the surgery. Sternum wires are usually made of materials like stainless steel or titanium that are compatible with the body and are biologically safe.
Risks Associated with MRI with Sternal Wires
An MRI is a diagnostic medical procedure that uses a magnetic field and radio waves to create images of the internal organs and tissues of the human body. While an MRI is generally considered a safe procedure, having sternal wires implanted in the chest may pose some risks, and precautions must be taken to ensure the safety of the patient.
- Metallic Interference:
- Dislodgement of Sternal Wires:
- Allergic Reactions:
The sternal wires may cause interference with the magnetic field of the MRI machine, leading to inaccurate images or interference with the function of the machine itself. In extreme cases, this can lead to burns or other injuries.
MRI uses powerful magnets to align and scan the body’s hydrogen atoms. If the magnetic field is strong enough, it can exert a force on a metallic object, causing it to move or even dislodge. This is especially a concern with sternal wires, which are close to the area being scanned.
Some patients may develop an allergic reaction to the contrast dye used in the MRI procedure. While this is rare, it is important to inform the medical staff of any allergies you may have before undergoing an MRI.
Before undergoing an MRI procedure with sternal wires, it is vital to inform your doctor and radiologist about the presence of these wires in your chest. In some cases, alternative diagnostic tests, such as a CT scan or ultrasound, may be recommended.
If an MRI is deemed necessary, steps can be taken to minimize the risks associated with sternal wires. These may include using alternative scan methods that do not produce as strong a magnetic field or placing a shielding device over the sternal wires to protect them from interference.
| Precautions for MRI with Sternal Wires |
|---|
| Inform your doctor and radiologist of the presence of sternal wires |
| Avoid any metal objects in the MRI room |
| Consider alternative diagnostic tests if sternal wires pose too great a risk |
| Use a shielding device over the sternal wires to protect them from interference |
By taking the necessary precautions and undergoing an MRI with sternal wires under the guidance of a qualified medical professional, patients can minimize the risks associated with this diagnostic test and ensure their continued health and well-being.
Non-Magnetic alternatives to sternal wires
Individuals who have undergone sternotomy surgery often have stainless steel wires or sutures to close their chest incision. These metallic objects can pose a risk during an MRI.
- Titanium wires: Rather than using stainless steel wires, some surgeons opt for titanium wires. These wires are non-magnetic and do not pose a risk during an MRI. However, they may not be as strong as stainless steel wires and may not be suitable for all patients.
- Adhesive sutures: Another alternative to sternal wires are adhesive sutures. These are made of a non-magnetic adhesive material and are suitable for individuals who have undergone a less invasive type of sternotomy.
- Barbed sutures: Barbed sutures, also known as self-retaining sutures, have become an increasingly popular alternative to sternal wires. They are strong, non-magnetic, and offer a secure closure. Unlike traditional sutures, barbed sutures do not require knots and are self-locking, which can reduce the risk of complications and decrease surgery time.
It is important to consult with your surgeon about the best sternal closure method for your individual circumstance. They can discuss the options with you and determine the best choice that will minimize risks during an MRI and promote a successful recovery.
In summary, alternatives to sternal wires include titanium wires, adhesive sutures, and barbed sutures. Your surgeon can advise you on which option is best for you.
Conclusion
Although sternal wires are commonly used to close incisions after sternotomy surgery, they can pose a risk when undergoing an MRI. Luckily, there are non-magnetic alternatives available such as titanium wires, adhesive sutures, and barbed sutures that can minimize these risks. It is important to discuss these options with your surgeon to determine the best option for your individual circumstances.
Magnetic Interference with Sternal Wires during MRI
Magnetic Resonance Imaging (MRI) is a medical imaging procedure that uses strong magnetic fields, radio waves, and a computer to produce detailed images of the body’s internal organs and structures. However, individuals with implanted metal devices or metallic fragments within their body may not be able to undergo MRI due to the possible magnetic interference.
