Board certified Radiologists specialize in interpreting diagnostic radiography exams for a prompt and accurate diagnosis. General radiography is available any time the clinic is open with an order from your physician. Mammography, Ultrasound, MRI, CT, and Bone Density are by appointment only. Our three satellite facilities in DeWitt, Fulton, and Morrison offer general radiography as well and all exams are available for any physician outside Medical Associates with an order.

Medical Associates has

  • 2 digital general radiography suites that provides almost instant access for physicians to view on their computers.
  • One digital mammography suite with Computer Aided Detection (CAD) that provides a "second look" at your mammogram.
  • 2 Ultrasound suites, with live 4-D Imaging
  • Dexa Bone Densitometry testing
  • 64-clice CT unit that allows us to offer calcium scoring and CTA's of the heart.
  • A 1.5 Tesla MRI unit.
  • All of our images are stored on a PACS system and you can obtain a CD of your images through our Health Information Department Monday through Friday from 8-5 by calling 563-243-2511 ext 7910 or 7915.

General Radiography

Medical Associates is equipped with 2 digital radiography rooms to provide you limited wait times. The images are available instantly for your physician to view on their computer. General radiography is available 7 days a week during the clinic's open hours.


Medical Associates is an accredited mammography facility that provides digital images for radiologist interpretation. Your mammograms are not only read by a board certified radiologist, but the images are also analyzed by computer aided detection (CAD). This assists the radiologist by giving your exam a computerized "second look" to draw attention to potential areas of concern. All exams are performed by registered technologists.

Medical Associates is committed to patient comfort and uncompromising image quality determined to provide patients with timely results. It is recommended by the American Cancer Society that women over 40 years of age have yearly mammograms. Early detection of breast cancer is your best protection. Medicare pays for a mammogram once every 12 months.

Medical Associates provides patients with appointment times Monday through Friday with occasional Saturdays and some evening appointment times are also available. Medical Associates can schedule a mammogram for anyone, as long as they have an order from their physician, even if it is not a Medical Associates provider.

For patients who feel they cannot afford a mammogram, we participate in the Iowa BCC program, Illinois Well Woman program, and Susan G. Komen for the Cure Vouchers.

Bone Densitometry

What is it?

A bone density is an exam done to help your doctor measure the health, or strength, of your bones. It is a non-invasive study that can accurately measure the density of your bones. This test compares your results with others in the same age group.

Why should I get this?

Osteoporosis is a disease in which the bones have become thin and weak. Bone density testing is the most accurate way to assess bone health. Early diagnosis can make a difference in your life. Therapy of osteoporosis has been shown to reduce the rate of fractures, especially in post-menopausal women.

How long does the test take?

This non-invasive test that can be done at Medical Associates is called a Dexa Bone Densitometry and takes approximately 15-20 minutes total.

When can I get the results?

Your physician will usually read the test in two to three days or sooner.

How do I get an appointment?

If you are a Medical Associates patient, your doctor's office can set one up for you. If your doctor is not a Medical Associates physician, he/she can have you bring the order, fax it to us, or call and set it up.

CT Scan

A CT (Computed Tomography) scan, sometimes called a CAT scan, is a radiology study that is used to visualize certain areas of the body slice by slice. During the exam you will lay on a padded table that will move in and out of the scanner. The scanner is shaped like a "doughnut" that is open on both ends. Claustrophobia is not a problem. The entire exam will last 30-45 minutes, depending on the exam. A board certified radiologist will interpret your exam and a report will be sent to your provider, who will then discuss the results with you.

CT Angiography

CT Angiography (CTA) is used to visualize the blood flow in vessels of the body without having to go to the Cardiac Cath Lab. This is a non-invasive way to examine the arterial system.

Preparing for your CT Exam

There is very little preparation for a CT Exam. You will be instructed at the time the appointment is made on any prep you may need. If you have any questions prior to your test, please call us at (563) 519-1838. Certain tests may require an injection of contrast material (dye). If you know you are allergic, please advise our staff before your appointment. After your exam, you may resume a normal diet, but may be instructed to drink extra fluids to help eliminate the contrast material from your system. If you are diabetic, follow the instructions you receive from the technologist.

Coronary CTA

A Coronary CTA is a heart-imaging test for evaluating whether fatty deposits or calcium deposits have built up in the coronary arteries, which supply blood to the heart. If left untreated, these areas of build-up, called plaque, can cause heart disease, which can lead to fatigue, shortness of breath, chest pain, or heart attack.

Cardiac Calcium Scoring

A Cardiac Calcium Score is a CT exam that checks for buildup of plaque on the walls of the coronary arteries, which supply blood to the heart. This test is used to check for heart disease in an early stage to determine the severity, which is sign of coronary artery disease.

Frequently Asked Questions

Is it OK to have metal in your body for a CT scan (plates, rods, pacemakers, etc)?
Yes. CT uses radiation, not a magnet to image the body.

If I need to fast, may I drink water?
Yes. If you need to take medication, you may have water. Also, if you need to take it with food, you may have a few crackers.

May I take medication?
Yes, unless otherwise specified by the staff.

Can I wear my own clothes?
Yes, if they have minimal metal on them so they don't interfere with the scan. Otherwise, we will provide you with a hospital gown.

How long will I be in the scanner?
Usually less than 30 minutes. Some of the appointment time is for paperwork and set-up.

Is it safe to have a CT scan due to the radiation?
The scanners used today use low radiation exposure and short scan times while still maintaining excellent image quality. Our protocols have been set up to use as little radiation as possible yet producing high quality images.
