State-of-the-Art Capabilities

To accurately diagnose and treat patients, health care providers may have to see what's happening inside their bodies. Medical imaging technology allows them to view a patient's internal condition, determine effective treatments and provide the best possible care.

In our Diagnostic Imaging Department, radiologic technologists and radiologists use innovative technologies to help our medical team evaluate, diagnose and treat patients. To learn more about our medical imaging capabilities, departments, or personnel, call us at (319) 768-4800 today.

Our Medical Imaging Services

A provider may recommend medical imaging if they feel it is necessary to better understand a patient's condition. The simplest medical images are X-rays, which are especially useful when a patient has an injury.

3D Mammography

3D images of the breast are created by using several low-dose digital X-rays taken at different angles. A computer converts the images into a stack of thin layers, allowing radiologists to review breast tissue one layer at a time.

In conventional 2-D mammography, overlapping tissue is a leading reason why small breast cancers may be missed and normal tissue may appear abnormal.

In a clinical study reported in the June 25, 2014 issue of The Journal of the American Medical Association, use of the Selenia Dimension system (used by Great River Medical Center) resulted in a:

  • 41 percent increase in the detection of invasive breast cancers
  • 40 percent reduction in false positive results
  • 29 percent increase in the detection of all breast cancers
  • 15 percent decrease in women recalled for additional imaging

We also offer:

  • Magnetic Resonance Imaging (MRI) - MRIs produce a full-body scan of the patient by generating a magnetic field that is sensitive to resonance produced by the human body. The resulting images allow radiologists to see what is happening inside a body in great detail.
  • Nuclear Medicine - Nuclear medicine uses low, safe amounts of radiation to highlight areas of a patient's body where a special dye has been introduced. There are various nuclear medicine procedures and your provider and radiologist can determine which one is needed in your case.
  • Positron Emission Tomography (PET) Scans - PET scans also uses low amounts of radiation to create internal images of a patient. In this case, a tracker (an injection or gas) is introduced into the patient, allowing the PET scanner to great images where the tracker releases gamma rays. PET scans are used to evaluate bodily functions, such as chemical reactions and metabolism.
  • Computerized Tomography (CT) Scans - CT scans use both computers and traditional x-rays to create vivid images of a patient's internal organs. CT scans are widely used to help treat a number of conditions, including cancer, stroke, traumatic injuries and cardiovascular issues.
  • Cardiac Calcium Scoring Test - During cardiac calcium scoring testing, patients lie down on their backs, and they are scanned in a computed tomography (CT) unit. Special images are taken of the heart while the patient holds his or her breath for about 20 seconds. Special cardiac-scoring software measures the amount of calcium in coronary arteries. Radiologists interpret the information and send the results to the patient’s health care provider within a week after the test. Learn more
