Imaging Services

Comprehensive Imaging Services

An accurate diagnosis needs accurate imaging. At Des Peres Hospital, our imaging services deliver clear, accurate images that aid with the diagnosis of a wide range of medical conditions and injuries.

Diagnostic X-Rays

X-ray imaging encompasses a wide range of techniques and applications. In general, X-ray imaging can be broken down into two major categories -- Radiographic and Fluoroscopic.

  • Fluoroscopy uses real-time X-ray imaging to allow doctors to see the movement of a body part. Fluoroscopy is generally used for upper and lower GIs, dysphagograms, barium swallows, ERCPs, myelograms, arthrograms and biopsies.
  • The majority of Radiographic X-rays chest and abdominal X-rays to detect abnormalities, fractures and/or trauma.

Digital Mammography

Digital mammography allows for easier detection of breast cancer in comparison to conventional mammography by providing radiologists with more information and higher quality information.

Benefits of the technology include:

  • Clearer images — Electronic images can be manipulated to improve resolution and contrast. They make it easier to view dense tissue and small tumors, and often eliminate the need for follow-up imaging.
  • Earlier detection — Studies suggest that 10 to 20 percent of breast cancers detected by self-examination were not visible on film X-rays. Digitally imaging the breast may improve a doctor’s ability to detect small tumors.
  • Improved care — According to a National Cancer Institute study, digital mammography was significantly better in screening women under age 50, women of any age with very dense or extremely dense breast tissue and pre- or perimenopausal women of any age.

We offer two types of mammograms — a screening mammogram for those with no symptoms and a diagnostic mammogram for those experiencing problems such as lumps, thickening, swelling and nipple discharge.

Bone Density Testing

We offer a fan beam bone density unit to detect osteoporosis, a disease that gradually weakens bones. This simple test takes about 15 minutes for the actual scan.


Ultrasound imaging is an important diagnostic tool used in monitoring pregnancy and identifying abnormalities in the breast, liver, gallbladder, pancreas, kidneys, uterus, ovaries, testes and thyroid. High-frequency sound waves are electronically generated to produce an image.

CT Scanning

Des Peres Hospital is equipped with a 64 slice computed tomography (CT) scanner CT is a medical diagnostic tool that allows the visualization of internal structures within the human body. It aids doctors in diagnosing disease by viewing internal abnormalities and assessing the extent of injury related to trauma. Des Peres Hospital offers all routine CT procedures: CT angiography, fluoroscopy, biopsies and 2-D, 3-D and 4-D reconstruction.

Here is what you can expect during your CT scan.

We also offer MAKOplasty CT pre-planning before a MAKOplasty knee resurfacing or hip replacement . If your surgeon determines you’re a good candidate for a MAKOplasty procedure, one or two weeks before your surgery date, we’ll take a CT image of your knee or hip. This is used to create a 3-D model of your joint and allows the surgeon to use the RIO® software to plan your surgery based on your unique anatomy.

Magnetic Resonance Imaging (MRI) Scanning

Des Peres Hospital is equipped with a 1.5T MRI unit. MRI uses magnetic energy and radio waves to image cross-sections of the body. The benefit of MRI is that, unlike CT, it does not use radiation to obtain images. MRI can be used to diagnose multiple abnormalities such as tumors, arterial venous malformation, injured tendons and ligaments, brain lesions, disk herniations and arterial stenosis.

Here are some tips for your MRI scan.

Nuclear Medicine Testing

Nuclear medicine employs the use of radioactive isotopes for diagnostic purposes. It’s primarily used to look at functional processes in the body, such as bone scans, thyroid scans, lung scans, renal scans, gallbladder function and liver scans.


We serve St. Louis area outpatients and can accommodate many special needs. For an appointment, call our scheduling office at (314) 966-9297.

What to Expect Patient Prep Tips

What to Expect – CT Scan

A "CT" or "CAT" scan is the term used to describe a radiologic test known as "computerized

tomography" (or computed axial tomography). The CT scanner uses advanced x-ray technology to take pictures of cross-sections of your body, called "slices." CT can see inside the brain and other parts of the body.

Prior to your visit:

• Our staff will contact you prior to your scheduled appointment date to confirm your upcoming visit.

On the day of your visit:

• Please bring a photo ID, your insurance information and the prescription from your physician to your appointment.

• Wear comfortable clothing.

• You may eat, drink and take medications as usual unless you are advised differently. Some tests will require fasting; our staff will advise you if this is necessary.

Following your visit:

• Our radiologists will interpret your images and send a report directly to your doctor. Your doctor will communicate the results of your exam to you.

What to Expect – MRI

MRI is a non-invasive procedure that uses powerful magnets and radio waves to construct pictures of the body. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the natural background magnetism from the earth. A very small percentage of hydrogen atoms within a human body will align with this field.

When focused radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, they will return a signal. The subtle differences in that signal from various body tissues enables MRI to differentiate organs, and potentially contrast benign and malignant tissue.

Here's what you can expect on the day of your visit.

• The exam takes from 45 minutes to an hour, during which time you will need to lie still on a comfortable padded table.

• We will try to make you as comfortable as possible during your exam. If you experience discomfort at any time, you will be able to communicate with the technologist through an intercom system.

• During the exam, you will hear humming, clicking and thumping sounds coming from the equipment. There is no need for alarm, as these sounds are part of the normal functioning of this type of equipment.

• For optimal imaging quality, it is important for you to remain as still as possible during your exam. Your technologist will provide pillows and pads to help you become comfortably positioned.

•  Wear comfortable clothing that is free from any metal, such as buttons and zippers. If this is not possible, we will provide you with a gown during your exam. Female patients may also wear a sports bra.

• Leave jewelry, hair pins and any metallic objects at home.

• Please notify the technologist of any prior surgeries or injuries where metal may be inside the body.

• Please bring any relevant outside X-rays or other exams for correlation.
