Frequently Asked Questions About CT Scans
Q: How long until my doctor will get results?
A: Typical report turnaround time is 24 hours or less.
Q: Can I get a copy of my images?
A: Yes, you can request a copy of your images on DVD from the technologists after your exam is completed. This is a courtesy patient copy, additional copies are subject to process and handling fees that medical records can provide more information on.
Q: What if I'm allergic to the contrast?
A: If you have a known history of contrast media allergy alert your doctor before scheduling so they can decide how they want to proceed (i.e. change to a without contrast exam or pre-medicate prior to exam).
Q: Will it hurt?
A: The scan will not hurt but if you have to have contrast, you will feel a needle stick and you may experience a warm flush sensation during the injection.
Q: Do I have to have an IV?
A: Some exams are performed with or without contrast. If your exam is ordered with intravenous contrast then you will be required to have an IV inserted for the exam.
Q: Do I have to drink anything?
A: Some exams do require you to drink oral contrast to better visualize anatomy and give you a better exam. This varies per exam and the technologists doing your exam will explain any special instructions your particular exam requires.
Q: Why do I need lab work?
A: To evaluate how well your kidney function is prior to contrast injection.
Q: How long will the exam take?
A: Usually 15-20 minutes is average once we have lab results. If additional imaging is need it could take longer.
Q: How is an MRI different from a CT?
A: CT and MRI images sometimes look very similar, but the equipment used to perform the scans is very different. CT uses ionizing radiation just as with a routine X-ray, while MRI uses a magnetic field. Depending upon the clinical indications, one may be preferred over the other, or both may be desired.
Q: I am scheduled for a CT Arthrogram. Is the procedure painful?
A: During the injection of contrast into the joint, you may feel some slight pressure or discomfort as the joint is distended. The sensation is temporary and will pass within 4-6 hours after the procedure. Some soreness may also be present at the injection site for up to 24 hours.
Q: How soon after my shoulder injection may I resume normal activities?
A: You may resume regular activities immediately after the procedure. The radiologist will recommend, however, that you limit strenuous or "stress-bearing" activities on the affected joint for 24 hours following the procedure.
