You should not take any type of calcium supplement, including multi-vitamins containing calcium, 48 hours prior to having the exam. You should also avoid having any exam that requires oral contrast for seven days before your Dexa scan.
Computerized Tomography (CT)
Preparation for cat scans depends on the type of scan that will be performed. You will be instructed at the time you make your appointment what you need to do, if anything, prior to coming for your exam. If you are or think you are pregnant, you should not undergo a CT scan due to the potential radiation exposure to the fetus.
Certain CT exams are performed with oral and/or IV contrast/dye.
Oral contrast, frequently a barium-based suspension, is usually taken before an exam of the abdomen and pelvis so that your intestines can be better seen and distinguished from other possible abnormalities that may occur in the abdomen.
IV contrast dye, contains iodine and is administered by vein. It is used to make specific organs, blood vessels, or certain tissues (such as tumors) more visible to the radiologist. It also often helps to better characterize and diagnose abnormalities. It is possible to have an allergic reaction to contrast, just like you can to any medication. At our facility we used a special type of contrast that helps to minimize the chances of any allergic reactions.
Before having your exam one of our trained technologists will assist you in filling out a screening form. This will allow the technologist, along with the radiologist, to assess the likelihood that you may have an allergic reaction to the contrast.
Claustrophobia is typically not a problem for a patient having a CT scan. The opening is large and not confining to the patient in any way.
You should not wear deodorant, talcum powder, or lotion under your arms on the day of the exam. These can appear on the x-ray film as calcium spots.
It is important that you obtain prior mammograms, if performed at another facility, and make them available to our radiologist at the time of the exam.
Magnetic Resonance Imaging (MRI)
Preparation for a MRI depends on the type of scan that will be performed. You will be instructed at the time you make your appointment what you need to do, if anything, prior to coming for your exam.
Depending on the exam ordered by you physician, you may be required to have contrast/dye administered by vein. It is extremely rare to have any type of allergic reaction to the contrast material.
If you are claustrophobic you may require mild sedation with oral valium or other medication prescribed by your physician to be taken prior to the exam. Please have someone drive you to the facility if you take any type of oral sedation.
You should wear comfortable, loose-fitting clothing for your US exam. Other preparation depends on the type of examination you will have.
You may be instructed to not eat or drink for as long as 6 hours prior to your appointment.
You may also be required to drink up 32 oz of water starting an hour before and finishing 45 minutes prior to the exam and avoid urinating, so that your bladder is full when the scan begins. This helps with visualization of the uterus, ovaries and bladder.
No appointment necessary for receiving an x-ray. Service is offered on a walk-in basis.
