CT Scanning
A CT (computed tomography) scan is a noninvasive medical test which combines the
diagnostic capability of x-ray with modern computer technology to create
multiple detailed images of inside the body that are too small for x-ray or are
located in areas that cannot be imaged by x-ray. The computer joins the images
together to produce cross-sectional views of the area being studied. CT scans
provide accurate diagnostic information without the risk associated with
diagnostic surgery. CT scanning is commonly used to diagnose problems such as
cancers, cardiovascular disease, infectious disease, trauma and musculoskeletal
disorders.
Yuma’s Radiology Department uses the latest CT scanning technology available,
including 3-dimensional imaging and sub-second scanning. Yuma District Hospital
recently acquired a Phillips 64-slice CT scanner. This top-of-the-line CT
scanner allows physicians to simultaneously capture multiple wafer-thin images
of a patient’s anatomy within seconds, shaving minutes off the exam time. The
system provides exceptionally high-resolution images that help doctors to more
accurately diagnose patients than ever before. CT provides detailed,
cross-sectional images of the brain, organs of the chest and abdomen; and bone
and tissue structures throughout the body. These images can be especially useful
in diagnosing tumors, bleeding or infections deep within large organs. To
enhance the diagnostic image, a dye or contrast medium is usually injected into
a vein or, for abdominal scans swallowed.
Other benefits for the patient include: less time needed for breath-holds;
greater flexibility (e.g., obtain thinner or thicker slices without rescanning
the patient); and better cross sectional displays and 3D images. In addition,
the scanner allows radiologists to use CT for new applications, such as CT
angiography, and cardiology.
CT Exam Preps:
Exam With IV Contrast-(Chest/Thorax, Abdomen, Pelvis)
1. Are you diabetic?
2. Do you have a history of kidney diease?
If yes to either of these questions, you will need lab work down PRIOR
to your CT exam.
3. NOTHING TO EAT 4 HOURS PRIOR TO EXAM.
Exam with Oral Contrast-
1. NOTHING TO EAT OR DRINK 4 HOURS PRIOR TO TEST.
2. Mix contrast with 24 ounces of non-carbonated beverage of choice.
3. Drink 2 HOURS PRIOR to exam-8 ounces every 30 minutes.
Yuma’s CT staff is credentialed by the American Registry of Radiologic
Technologists and is CAT scan registered.
