Has your doctor asked you to visit a radiology center to get a CT angiogram?
If so, then you may have questions about this procedure and what to expect.
Continue reading to learn about this type of angiography before your
CT scan in San Antonio.
What It Is
CT angiography makes use of the latest CT technology and involves taking
images of the body. Combining thin section reconstruction with fast scanning,
CT angiography can provide exceptional detail of organs and blood vessels.
Some of the conditions that doctors use CT angiography to diagnose include
coronary artery disease, renal artery stenosis, and thoracic aorta aneurysm.
What to Expect
During the procedure, you will be given an I.V. line, and contrast dye
will be injected. This step will take about 10 to 30 seconds and may cause
you to experience a funny taste in your mouth or a warm sensation. As
the CT scan is performed, you will need to hold your breath for a short time.
How to Prepare
To get ready for your CT angiogram, you should not eat within 3 hours of
your appointment at the imaging center. However, you should drink plenty
of fluids, ideally water, while avoiding caffeinated beverages. Also,
wear clothing that is comfortable and will allow easy access for the I.V.
line. Before the scan, inform the nurse or radiologist of any allergies
that you know of and do not hesitate to ask questions or express any concerns
that you may have about the CT angiogram.
After Your Scan
Following your CT angiogram, you can resume your normal activities, eat
normally, and should continue to drink plenty of fluids over the next
24 hours. If you experience any issues or have questions, then contact
your physician or radiologist.
Interpreting the Results
A CT angiogram may include as many as thousands of axial slices, which
are thin, individual CT scans. In combination with 3D imaging tools and
other methods of analysis, these images are reviewed. After the information
is analyzed, your referring physician should receive a report of any significant
findings about a day after your scan.
