Understanding CT



What is CT Scan?

CT or CAT scan stands for computed axial tomography.  A CT scan uses an X-ray tube that travels 360 degrees around your body while gathering information from multiple views to create cross-sectional images. It is like selecting a slice of bread out of a loaf.


What to expect during your CT Scan

A board certified CT technologist will be the individual performing your exam. The technologist will explainthe entire procedure to you and provide any specific instructions for the scan. You may need to hold your breath at times. Also an IV, in your arm, may be necessary if a contrast medium or dye is required.

Some exams require that you drink an oral contrast agent. If this is necessary, the technologist will provide you the contrast and inform you about when to drink it prior to the scan.

It is very important not to move during the exam. You will be positioned on a scan table. Then you will be moved into the scanner. The technologist will have you in full view at all times and be in constant communication via two-way microphones and monitors. During this brief time, you will hear humming of the equipment as it produces the images. The scan table will move a different images are produced.


Important Information

Inform the technologist if you may be pregnant. If there is any possibility of pregnancy, a pregnancy test may be ordered prior to the exam.

Please bring a list of your current medications. The technologist will ask you several questions before your exam. This history will include previous allergies you have had (especially to iodine), a previous reaction to X-ray “dye,” renal problems or diabetes. Inform the technologist if you are taking glucophage, metformin, glucovance, metaglip or avanament.

If your physician orders for you to have IV contrast, the technologist will insert a small IV catheter into one of your arms for administration of the contrast. If you feel any discomfort during a contrast injection, tell the technologist. A temporary flush, wave of nausea or metallic taste in the mouth are common side effects, but should be reported to the technologist.

If you observe any tenderness, swelling, or problems in the area of the injection site or arm where contrast was administered within 48 hours after injection, call the department and talk with a CT technologist or the radiology nurse.


Preparation for the Exam

Each CT exam has required preparations. The most frequently performed exams are listed below, along with preparation instructions:

Drink a half bottle of the RediCat an hour before the exam and the remaining half bottle 30 minutes before exam time. Do not eat or drink anything after you ingest the RediCat. IV contrast is routinely administered through an IV in the arm. The exam takes 15 to 30 minutes.

Pelvis

Drink half a bottle of the oral contrast RediCat an hour before the exam, and the remaining half bottle 30 minutes before exam time. Do not eat or drink anything else after you ingest the RediCat. IV contrast is routinely administered through an IV in the arm. The exam takes 15 to 30 minutes.
