Magnetic
Resonance Imaging (MRI) uses a magnetic field and radio waves (no
radiation) to create an image of many parts of the body, especially
the brain, spine, and joints.
AHI Dallas utilizes the Siemens Magnetom Open Viva, which represents the highest
advances in MRI technology, including the most recent sophisticated
diagnostic software upgrades. The open MRI provides clear, unobstructed
space on three sides, allowing a pleasant non-claustrophobic exam. The
openness also facilitates the scanning of large people with a higher
level of comfort. You will be able to see and communicate with the technologist
performing your exam. To add further comfort, you may have a family
member or friend sit in the room with you.
American Health Imaging of Dallas is excited to offer state-of-the-art MR High Field imaging services to our market. With the installation of the Signa HDe 1.5T from GE, AHID can offer the most precise image quality and clinical performance without compromising patient comfort. Using new magnet design and technology, the short bore 1.5T MRI system delivers better accommodations than any other high field design for the needs of all patients, including those who suffer from claustrophobia. The result is the shortest whole body magnet available.
A typical exam will last between 30 and 60 minutes and requires no special
preparation. You should eat normally and follow the normal dosage of
your prescribed medications unless your doctor gives instructions to
do otherwise. For more information about your MRI procedure, see the
Exam Preparation, What
to Expect, and Frequently Asked Questions

Computed Tomography (CT) , widely known as a CAT scan, is medically referred
to as simply CT. In its early days of development and use, it was called
Computerized Axial Tomography, hence the term CAT. At American Health
Imaging of Dallas, we have the Siemens Brightspeed Elite 16 slice CT machine.
CT is generally a relatively quick procedure that uses x-ray beams to
create computer-generated image of soft tissue structures, such as tumors
and internal organs, and air cavities (sinuses, lungs). It also has
advantages in skeletal and neurological imaging. Its radiation doses
to the human body are considered minimal due to the speed in which the
x-ray is delivered.
The procedure requires you to lie in a horizontal position, either on
your back or stomach, and remain comfortably still. A flat, moving table
goes through the center of a donut-shaped x-ray machine. X-ray beams
from a number of positions are aimed at the area being studied. A special
detector measures the amount of absorbed radiation. This data is transformed
by a computer into a digital image.

Preparation and Frequently Asked Questions
