MRI & CT Scans in San Antonio, TX
MRI (magnetic resonance imaging) and CT (computed tomography) scans are noninvasive medical imaging techniques used to diagnose or monitor injuries and illnesses, including cancer and heart disease. Both of these imaging diagnostics may be combined with the use of a contrast dye to more accurately image abnormal tissues or organ functions. If you need to schedule either an MRI or CT scan near San Antonio, Concord Imaging can meet all your imaging diagnostic needs.
The Differences Between MRI and CT Scans
Although MRI and CT scans both create images of the body’s interior for diagnosis and monitoring purposes, these two diagnostics are quite different. Whether you receive an MRI or CT scan will ultimately depend on your condition and your physician’s best judgment.
- CT scans use a thin X-ray beam to image tissue, bone, and organs. These diagnostics use radiation to create images. Because bone appears opaque in an X-ray image, CT scans are excellent for diagnosis and monitoring of diseases and injuries of the skeletal system, including inner ear issues. Contrast dyes used during CT scans are iodine-based.
- MRI imaging uses magnetic fields and radio waves to briefly affect the hydrogen atoms in the cells of your body, creating images. No radiation is used during this procedure. This type of imaging provides great detail of soft tissues and organs, but is not as effective at imaging the bones. MRI contrast solutions are not iodine-based.
Ways to Relax During Your MRI or CT Scan
When you undergo either an MRI or CT scan, you will be asked to lie back on a movable bed that retracts into a large cylinder for imaging. You will be asked to lie very still during your procedure. If you are feeling nervous about your MRI or CT scan, there are various techniques you can use to help you feel more relaxed and comfortable. If you have questions about your imaging diagnostic, you can learn more by calling Concord Imaging at (210) 572-2222.
- Ask your physician or imaging technician ahead of time about sedative medications to help you relax. Many people choose sedatives for enhanced comfort during magnetic resonance or X-ray imaging.
- Load relaxing music onto a portable player. In most cases, you can bring music and headphones with you during an MRI or CT scan to help you relax.
- Practice deep breathing or mild meditation techniques to help your body and mind stay relaxed during your procedure.
- Keeping your eyes closed during the exam can also help you feel more relaxed. Try to visualize yourself in a familiar or calming place, such as your bedroom or a sunny beach.
