It is very important for women to inform their physician and Radiologic Technologist if there is any possibility that they are pregnant.
Common Fluoroscopy Exams:
The skin around the joint to be examined will be cleansed with an antiseptic and a local anesthetic will be injected into the area around the joint. The fluoroscopic exam will show correct needle placement, and a contrast agent and/or air will then be injected into the joint space. This examination is usually completed within 30 minutes.
During a hysterosalpingogram a contrast agent is injected through a thin tube that is inserted through the vagina into the uterus. Because the uterus and fallopian tubes are connected, the contrast agent will flow into the fallopian tubes. “Live” x-ray pictures are being taken as the contrast agent is being administered.
This test should be performed 10 days from the onset of your menses. This examination is completed in approximately 30 minutes.
Lower GI tract/Barium Enema
During the barium enema exam liquid barium, a dense non-absorbable metallic solution, is introduced into the colon through a rectal tube. The barium coats the inside of the rectum, colon, and part of the lower small intestine. As the barium is being administered “live” x-ray pictures are being taken. The patient may be repositioned numerous times to enable the radiologist to capture views of their colon from several angles. Once the x-ray images are completed most of the barium is drained back into a bag and the patient is directed into the restroom to expel the remaining barium. This test usually takes approximately 45 minutes to 1 hour.
For patients who cannot have an MRI exam for any reason, a myelogram may be performed, followed by a CT scan. A myelogram is done to provide a very detailed picture of the spinal cord and spinal column, and of any abnormalities that may be present. A myelogram is performed with the patient lying face down on the x-ray table. After locating the best placement for the needle, your skin will be cleaned and numbed with a local anesthetic. The contrast agent is then injected and the x-ray table is slowly tilted. During this time, the flow of contrast is monitored by the radiologist.
After the myelogram, patients will stay in a recovery room from 1 to 4 hours, resting with your head elevated at a 30 to 45 degree angle. You will be encouraged to take fluids at this time to help eliminate contrast material from your body and prevent headaches. This examination usually takes approximately 45 minutes. Our nurses will contact you to instruct you on the preparation for this exam.
Upper GI tract
In order to visualize these organs, patients will be given barium to drink. The radiologist will monitor the flow of barium through your upper gastrointestinal tract by “live” x-ray as the patient is drinking the barium. First you will be standing up, then lying down, as the radiologist obtains pictures of your esophagus and stomach. You will be asked to hold your breath to prevent blurring of the still images. Also, periodically you will be asked to move into different positions while standing, and to roll into different positions while lying down on the table.
The preparation for this examination is to have nothing to eat or drink after midnight or 8 hours before the exam. This includes no gum chewing or smoking. This examination usually takes about 30 minutes.
Small Bowel Series
Voiding Cystourethrogram (VCUG)
Intravenous Pyelography (IVP)
IVP’s have widely been replaced by CT Urograms where CT images are collected for this purpose.
