Read on to discover the key differences between CT scans and MRIs, and find out which option suits your medical needs. Stay informed and make the best imaging choices with Smart Scan.
What is a CT Scan?
A CT (computed tomography) scan, also known as a CAT (computerized axial tomography) scan, uses X-rays to create detailed, cross-sectional images of the body. During the procedure, the patient lies on a motorized table that moves through a circular opening of the CT scanner. The scanner rotates around the patient, sending a series of X-ray beams from different angles. These beams are detected and processed by a computer to construct a series of images, which can be viewed individually or assembled into a three-dimensional representation of the internal structures.
CT scans are highly effective in emergency situations, primarily for identifying bone fractures, tumors, and internal bleeding. They can also help detect blood clots, joint problems, and the development of cancer. Due to their speed and accuracy, CT scans provide quick diagnostic information that helps guide treatment decisions.
What is an MRI Scan?
An MRI (magnetic resonance imaging) scan is a non-invasive imaging technique that uses powerful magnets and radio waves to generate detailed images of the body's organs and tissues while the patient remains still inside a large, cylindrical machine. Unlike CT scans, MRIs do not use ionizing radiation, making them a safer option for certain patients, such as those requiring multiple imaging tests or pregnant women.
MRIs are particularly useful for detecting neurological conditions, soft tissue injuries, and identifying abnormalities in the brain, spinal cord, and joints. With our GE 1.5 Tesla wide bore scanner at Smart Scan, the procedure can take as little as 15 to 20 minutes.
What Is The Difference Between an MRI & CT Scan?
Aside from the fundamental differences in their technology, they have some key distinctions in terms of what they are best suited for.
- Imaging Capabilities: Both MRI and CT images can show bones, organs, and soft tissues, but ultimately, MRI results are more detailed, allowing for better visualization of these structures.
- Use of Contrast Dyes: Both imaging techniques can use contrast agents to enhance the visibility of specific structures in the body. However, the dye used for CT scans is iodinated, meaning it contains iodine, while the dye used for MRIs is gadolinium-based. For patients with allergies or kidney issues, MRIs may be a better option.
- Radiation Exposure: CT scans use radiation to produce images, which can be a risk factor for patients with existing health conditions or those who require multiple imaging procedures. MRIs do not use radiation, making them a safer choice for individuals needing frequent imaging or for pregnant women.
- Procedure Time: CT scans are typically quicker, and often completed in just a few minutes. MRI scans take longer, usually ranging from 15 to 30 minutes, depending on the area being examined. At Smart Scan, we can reduce the time you spend in the machine, making for a more comfortable experience with our GE 1.5 Tesla wide bore scanner.
- Comfort and Noise: The cylindrical MRI machine can be noisy, which might cause discomfort for some patients. In contrast, the CT scanning process is generally quieter.
- Cost: Generally, CT scans are less expensive than MRIs, however in locations like Eau Claire, Wausau, and Madison, an MRI may be much less expensive at Smart Scan because of the monopolies held by the big hospital systems, allowing price gauging. The cost of an MRI or CT scan in these areas can reach up to $6,400. At Smart Scan, an MRI costs $650 for the standard scan without contrast and $850 for a comprehensive scan with and without contrast. This price covers both the MRI procedure and the radiologist's report.
How to Choose Between a CT Scan & an MRI
Ultimately, the choice between a CT scan and an MRI depends on your situation and medical needs, and you should be able to discuss this with your doctor. If your healthcare provider needs to quickly identify conditions like brain bleeding or bowel obstruction, a CT scan is more appropriate due to its speed.
On the other hand, if your physician needs highly detailed images of your body's internal structures to help diagnose or treat an issue, an MRI is the better option. The radiologists at Smart Scan are available for consultation for deciding the best exam to get.
You might also consider the following factors when deciding between a CT scan and an MRI:
- Pre-existing Conditions: If you have any pre-existing conditions or are pregnant, it's crucial to discuss your options with your healthcare provider before scheduling an imaging test. They can advise on the safest and most effective option for your situation.
- Implanted Medical Devices: The magnetic fields used during an MRI scan may affect some metallic implants, such as pacemakers. In these cases, a CT scan may be used instead.
- Previous Imaging Tests: Depending on your medical history, previous imaging tests may influence which option will provide the most accurate results.
- Cost and Insurance Coverage: If you have insurance coverage, it's best to check with your provider beforehand to understand what is covered and any potential out-of-pocket costs for both CT scans and MRIs.
