| Types of Images From the patient's point of view, radiology has not changed much over
the years. However, the image being produced has improved drastically. Most people are familiar with routine
x-rays. However, Coryell
Memorial offers not only routine procedures but also fluoroscopic
procedures. The fluoroscope allows the radiologist to see the area
of interest while making the pictures. These exams include, but are not
limited to UGI, small bowel and colon studies. Fluoroscopic procedures
may take anywhere from 30 minutes to several hours.
Ultrasound is a painless imaging modality that produces an
image by sound waves traveling through the area of interest. The
sonographer will need to place a clear gel-like substance on the area
and then move the transducer over your skin. Most procedures take
between 30 minutes and an hour. CT stands for computed
tomography. X-ray is the source of radiation used but with the added
computer technology, it shows anatomy in cross-section. You may be given
something to drink prior to your exam. you may also need an IV started
for the injection of a contrast agent that enhances the anatomy
visualized. You will enter a small tunnel and you will be told when to
breath in or out. Nuclear medicine is where a radioactive
isotope is mixed with something that will direct the dose to a
particular organ. The dose may be injected by IV, taken orally or
inhaled depending on the organ that needs to be visualized. The
equipment picks up the radiation and produces an image of the area.
Mammography is an x-ray of the breast. Women forty years and older
should have a mammogram performed yearly. This is called a screening
mammogram and it takes about 20 minutes to complete. A diagnostic
mammogram is for when you or your physician has found a lump in your
breast or the radiologist saw something on your screening mammogram.
These exams take about an hour but could be longer if the radiologist
decides you might need an ultrasound. If scheduled for a diagnostic
mammogram please plan on being in the Imaging Department for up to two
hours.
Magnetic Resonance Imaging (MRI) is newly available at
CMHS. This technology provides an enhanced way to distinguish
pathologic tissue (such as a tumor) from normal tissue. The procedure is
harmless to the patient. Preparations Any of the modalities may require that
you follow special preparations the day before and/or the day of the
exam. If given a preparation sheet, please follow the instructions or
your exam may not be able to be completed at the scheduled time. Your
imaging exams are interpreted by a specialty physician that passed an exam to be certified by the American College of
Radiology. Coryell Memorial, in conjunction with Scott & White Hospital,
stores x-rays on a special computerized system. Your physician, using
a password protected program, can look at your x-rays, ultrasound, and
CT scan in addition to the radiologist's report on his/her computer.
Together, these various modalities will assist
your physician in making a diagnosis and in the planning of your
treatment. Back to Healthcare
