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

- 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.
