Here are a few of the imaging services we offer at Saint Louis University Hospital and what you need to know before coming in:
You do not have to do anything special before this test.
CTA (CT Angiography)
Please do not eat or drink anything two hours prior to your test. Wear comfortable clothes.
If your doctor said that your CT scan would be “with IV contrast,” you should not eat or drink anything for two hours prior to your test. If you know you are allergic to iodine, which is the contrast injected into your vein, you should let your doctor know.
If you are having a basic X-ray of the chest, arms or legs, you don’t need to do anything special before this test.
Interventional radiology treatment involves a tiny pin-hole incision in your wrist or groin. Your doctor will usually instruct you to not eat or drink anything for 8 to 12 hours before this procedure. Learn more about interventional radiology services.
Digital mammography uses a low-dose X-ray to examine breasts. This service provides excellent image quality, immediate access to patient information and reduces procedural discomfort.
The Three Tesla Magnetic Resonance Scanner (3T MRI), Intraoperative Magnetic Resonance Scanner (iMRI) and Open Tesla Magnetic Resonance Scanner (Open MRI) give physicians advanced imaging technology to more accurately diagnose a broad spectrum of disease and conditions.
3T MRI, 1.5T MRI and High Field Open MRI (Magnetic Resonance Imaging)
For MRIs of the kidney, liver, pancreas and spleen, please do not eat or drink anything for eight hours before your test.
PET/CT (Positron Emission Tomography/Computed Tomography) Scan
Please do not eat or drink anything except water for four hours before your test. Also, do not engage in strenuous exercise for 24 hours before your test. You may drink water at any time. Drinking extra water is helpful. You may also take your medications, except insulin, at any time. If you are a diabetic on insulin, please call us before the day of your test for special instructions. Your test will take two or three hours. Wear comfortable clothing, without any metal, if possible. Women may wear a bra. Gowns are available, if needed.
For ultrasounds of your abdominal region (stomach, bile ducts, liver, gallbladder or pancreas), please do not eat or drink anything 6 - 8 hours before the test.
For ultrasound of your urinary tract, bladder or pelvis, you must have a full bladder during the test. This might be uncomfortable. Please drink at least 32 ounces of water 45 minutes before you come and try not to visit the restroom until your test is completed.
